public class TreeGrid extends ListGrid implements HasDataArrivedHandlers, HasDataChangedHandlers, HasFolderClickHandlers, HasFolderClosedHandlers, HasFolderContextClickHandlers, HasFolderOpenedHandlers, HasLeafClickHandlers, HasLeafContextClickHandlers, HasNodeClickHandlers, HasNodeContextClickHandlers, HasFolderDropHandlers
The Smart GWT system supports hierarchical data (also referred to as tree data due to its "branching" organization) with:

- the `Tree` class, which manipulates hierarchical data sets
- the TreeGrid widget class, which extends the ListGrid class to visually present tree data in an expandable/collapsible format.

For information on DataBinding Trees, see `TreeDataBinding`.

A TreeGrid works just like a `ListGrid`, except one column (specified by `TreeGridField.treeField`) shows a hierarchical `Tree`. A TreeGrid is not limited to displaying just the `Tree` column - you can define additional columns (via `fields`) which will render just like the columns of a `ListGrid`, and support all of the functionality of ListGrid columns, such as `formatters`.

Except where explicitly overridden, `ListGrid` methods, callbacks, and properties apply to TreeGrids as well. The `ListGrid` defines some methods as taking/returning `ListGridField` and `ListGridRecord`. When using those methods in a TreeGrid, those types will be `TreeGridField` and `TreeNode`, respectively.

  - ### setAlwaysShowOpener

    public TreeGrid setAlwaysShowOpener(Boolean alwaysShowOpener)
    If `showOpener` is true, should we display the opener icon for folders even if they have no children?

    Note that for trees which `load data on demand`, we may not know if a folder has any descendants if it has never been opened. As such we will show the opener icon next to the folder. Once the user opens the icon and a fetch occurs, if the folder is empty, and this property is false, the opener icon will be hidden.

    For more information on load on demand trees, and how we determine whether a node is a a folder or a leaf, please refer to the `TreeDataBinding` documentation.

    Parameters:
      `alwaysShowOpener` - New alwaysShowOpener value. Default value is false
    Returns:
      `TreeGrid` instance, for chaining setter calls

  - ### getAlwaysShowOpener

    public Boolean getAlwaysShowOpener()
    If `showOpener` is true, should we display the opener icon for folders even if they have no children?

    Note that for trees which `load data on demand`, we may not know if a folder has any descendants if it has never been opened. As such we will show the opener icon next to the folder. Once the user opens the icon and a fetch occurs, if the folder is empty, and this property is false, the opener icon will be hidden.

    For more information on load on demand trees, and how we determine whether a node is a a folder or a leaf, please refer to the `TreeDataBinding` documentation.

    public TreeGrid setAutoAssignTreeField(boolean autoAssignTreeField) throws IllegalStateException
    If this grid was passed an explicit set of fields, but no field was specified as the "tree-field" (showing indentations for tree hierarchy and tree icons), should we assign one of the other fields to be the tree-field?

    When true, if we're showing a field for the `Tree.titleProperty` of the tree, this will be displayed as a Tree Field by default. If not, the first entry in the specified fields array will be used.

  - ### setCanDragRecordsOut

    public TreeGrid setCanDragRecordsOut(Boolean canDragRecordsOut)
    Indicates whether records can be dragged from this listGrid and dropped elsewhere.

    NOTE: If `canDragRecordsOut` is initially enabled or might be dynamically enabled after the grid is created, it may be desirable to disable `touch scrolling` so that touch-dragging a record starts a drag operation rather than a scroll, but see the discussion of `drag handles`. If `Canvas.disableTouchScrollingForDrag` is set to `true`, then touch scrolling will be disabled automatically. However, for `accessibility` reasons, it is recommended to leave touch scrolling enabled and provide an alternative set of controls that can be used to perform drag and drop of records out of the grid.

    Overrides:
      `setCanDragRecordsOut` in class `ListGrid`
    Parameters:
      `canDragRecordsOut` - New canDragRecordsOut value. Default value is false

  - ### getCanDragRecordsOut

    public Boolean getCanDragRecordsOut()
    Indicates whether records can be dragged from this listGrid and dropped elsewhere.

    NOTE: If `canDragRecordsOut` is initially enabled or might be dynamically enabled after the grid is created, it may be desirable to disable `touch scrolling` so that touch-dragging a record starts a drag operation rather than a scroll, but see the discussion of `drag handles`. If `Canvas.disableTouchScrollingForDrag` is set to `true`, then touch scrolling will be disabled automatically. However, for `accessibility` reasons, it is recommended to leave touch scrolling enabled and provide an alternative set of controls that can be used to perform drag and drop of records out of the grid.

    Overrides:
      `getCanDragRecordsOut` in class `ListGrid`
    Returns:
      Current canDragRecordsOut value. Default value is false

  - ### setCanDropOnLeaves

    public TreeGrid setCanDropOnLeaves(Boolean canDropOnLeaves)
    Whether drops are allowed on leaf nodes.

    Dropping is ordinarily not allowed on leaf nodes unless `canReorderRecords` is set.

    The default action for a drop on a leaf node is to place the node in that leaf's parent folder. This can be customized by overriding `folderDrop()`.

    Note that enabling `canDropOnLeaves` is usually only appropriate where you intend to add a custom `folderDrop()` implementation that does not add a child node under the leaf. If you want to add a child nodes to a leaf, instead of enabling canDropOnLeaves, use empty folders instead - see `Tree.isFolder()` for how to control whether a node is considered a folder.

    Note : This is an advanced setting

    Parameters:
      `canDropOnLeaves` - New canDropOnLeaves value. Default value is false
    Returns:
      `TreeGrid` instance, for chaining setter calls
    See Also:
      - `TreeGrid drag and drop`

  - ### getCanDropOnLeaves

    public Boolean getCanDropOnLeaves()

  - ### setCanDropSiblingAfterLastNode

    public TreeGrid setCanDropSiblingAfterLastNode(boolean canDropSiblingAfterLastNode)
    When performing a drag and drop to add or move data within the tree, should users be able to make the dropped node a sibling of the last node in the tree by dropping just below it?

    When set to true, if a user performs a drop action in the space immediately below the last node, (less than half the grid's specified cellHeight away), the dropped data will be added to the parent of that last node, making them siblings. If the parent `will not accept drops`, the dropped data will be added to the first ancestor that will accept a drop.

    If the user performs the drop lower down in the empty area below the last row, of if this property is set to `false`, the dropped data will be added as a last child to the root node instead.

    Note : This is an advanced setting

    Parameters:
      `canDropSiblingAfterLastNode` - New canDropSiblingAfterLastNode value. Default value is true
    Returns:
      `TreeGrid` instance, for chaining setter calls

    Returns:
      Current canDropSiblingAfterLastNode value. Default value is true

  - ### setCanReorderRecords

    public TreeGrid setCanReorderRecords(Boolean canReorderRecords)
    Indicates whether records can be reordered by dragging within this `ListGrid`.

    NOTE: If `canReorderRecords` is initially enabled or might be `dynamically enabled` after the grid is created, it may be desirable to disable `touch scrolling` so that touch-dragging a record starts a reorder operation rather than a scroll, but see the discussion of `drag handles`.

  - ### setConnectorImage

    public TreeGrid setConnectorImage(String connectorImage) throws IllegalStateException
    The base filename or `stateful image block` for the connector icons shown when `showConnectors` is true. Connector icons are rendered into the title field of each row and show the dotted hierarchy lines between siblings of the same parent node. For each node, a connector icon may be shown:
    - As an opener icon for folder nodes, next to the folder icon
    - In place of an opener icon for leaf nodes, next to the leaf icon
    - As a standalone vertical continuation line in the indent to the left of the node, to show a connection between some ancestor node's siblings (only relevant if `showFullConnectors` is true).
    Note that `showFullConnectors` governs whether connector lines will be displayed for all indent levels, or just for the innermost level of the tree.

    When set to an `SCImgURL`: the stateful filenames for these icons are assembled from this base filename and the state of the node. Assuming the connectorImage is set to `{baseName}.{extension}`, the full set of images to be displayed will be:

    `{baseName}_ancestor[_rtl].{extension}` if `showFullConnectors` is true, this is the URL for the vertical continuation image to be displayed at the appropriate indent levels for ancestor nodes with subsequent children.

    For nodes with no children:

    - `{baseName}_single[_rtl].{extension}`: Shown when there is no connector line attached to the parent or previous sibling, and no connector line to the next sibling. For `showFullConnectors:true` trees, there will always be a connector leading to the parent or previous sibling if its present in the tree so this icon can only be displayed for the first row.
    - `{baseName}_start[_rtl].{extension}`: Shown when the there is no connector line attached to the parent or previous sibling, but there is a connector to the next sibling. As with `_single` this will only ever be used for the first row if `showFullConnectors` is true
    - `{baseName}_end[_rtl].{extension}`: Shown if we are not showing a connector line attached to the next sibling of this node (but are showing a connection to the previous sibling or parent).
    - `{baseName}_middle[_rtl].{extension}`: Shown where the we have a connector line leading to both the previous sibling (or parent) and the next sibling.
    For folders with children. Note that if `showFullConnectors` is false, open folders will never show a connector to subsequent siblings:
    - `{baseName}_opened_single[_rtl].{extension}` opened folder node with children when no connector line is shown attaching to either the folder's previous sibling or parent, or to any subsequent siblings.
    - `{baseName}_opened_start[_rtl].{extension}`: opened folder with children when the there is no connector line attached to the parent or previous sibling, but there is a connector to the next sibling.
    - `{baseName}_opened_end[_rtl].{extension}`: opened folder with children if we are not showing a connector line attached to the next sibling of this node (but are showing a connection to the previous sibling or parent).
    - `{baseName}_opened_middle[_rtl].{extension}`: opened folder with children where the we have a connector line leading to both the previous sibling (or parent) and the next sibling.
    - `{baseName}_closed_single[_rtl].{extension}` closed folder node with children when no connector line is shown attaching to either the folder's previous sibling or parent, or to any subsequent siblings.
    - `{baseName}_closed_start[_rtl].{extension}`: closed folder with children when the there is no connector line attached to the parent or previous sibling, but there is a connector to the next sibling.
    - `{baseName}_closed_end[_rtl].{extension}`: closed folder with children if we are not showing a connector line attached to the next sibling of this node (but are showing a connection to the previous sibling or parent).
    - `{baseName}_closed_middle[_rtl].{extension}`: closed folder with children where the we have a connector line leading to both the previous sibling (or parent) and the next sibling.
    (Note '[_rtl]' means that "_rtl" will be attached if isRTL() is true for this widget).

    If `showSelectedOpener` is true the URL for selected nodes will append the string `"_selected"` to the image URLs described above. So for a connectorImage set to `{baseName}.{extension}`, the URLs for selected records would be `{baseName}_ancestor[_rtl]_selected.{extension}`, `{baseName}_single[_rtl]_selected.{extension}`, etc.

    When set to an SCStatefulImgConfig</>: it should contain entries for the default _base state, as well as the custom states listed above. These entries may be set to any combination of supported src strings, including file-paths and sprite-strings.

    Parameters:
      `connectorImage` - New connectorImage value. Default value is "[SKIN]connector.gif"
    Returns:
      `TreeGrid` instance, for chaining setter calls
    Throws:
      `IllegalStateException` - this property cannot be changed after the component has been created

    - `{baseName}_opened_start[_rtl].{extension}`: opened folder with children when the there is no connector line attached to the parent or previous sibling, but there is a connector to the next sibling.
    - `{baseName}_opened_end[_rtl].{extension}`: opened folder with children if we are not showing a connector line attached to the next sibling of this node (but are showing a connection to the previous sibling or parent).
    - `{baseName}_opened_middle[_rtl].{extension}`: opened folder with children where the we have a connector line leading to both the previous sibling (or parent) and the next sibling.
    - `{baseName}_closed_single[_rtl].{extension}` closed folder node with children when no connector line is shown attaching to either the folder's previous sibling or parent, or to any subsequent siblings.
    - `{baseName}_closed_start[_rtl].{extension}`: closed folder with children when the there is no connector line attached to the parent or previous sibling, but there is a connector to the next sibling.
    - `{baseName}_closed_end[_rtl].{extension}`: closed folder with children if we are not showing a connector line attached to the next sibling of this node (but are showing a connection to the previous sibling or parent).
    - `{baseName}_closed_middle[_rtl].{extension}`: closed folder with children where the we have a connector line leading to both the previous sibling (or parent) and the next sibling.
    (Note '[_rtl]' means that "_rtl" will be attached if isRTL() is true for this widget).

    If `showSelectedOpener` is true the URL for selected nodes will append the string `"_selected"` to the image URLs described above. So for a connectorImage set to `{baseName}.{extension}`, the URLs for selected records would be `{baseName}_ancestor[_rtl]_selected.{extension}`, `{baseName}_single[_rtl]_selected.{extension}`, etc.

    When set to an SCStatefulImgConfig</>: it should contain entries for the default _base state, as well as the custom states listed above. These entries may be set to any combination of supported src strings, including file-paths and sprite-strings.

    Parameters:
      `connectorImage` - New connectorImage value. Default value is "[SKIN]connector.gif"
    Returns:
      `TreeGrid` instance, for chaining setter calls
    Throws:
      `IllegalStateException` - this property cannot be changed after the component has been created
    See Also:
      - `SCImgURL`

  - ### getConnectorImageAsSCStatefulImgConfig

    public SCStatefulImgConfig getConnectorImageAsSCStatefulImgConfig()
    The base filename or `stateful image block` for the connector icons shown when `showConnectors` is true. Connector icons are rendered into the title field of each row and show the dotted hierarchy lines between siblings of the same parent node. For each node, a connector icon may be shown:
    - As an opener icon for folder nodes, next to the folder icon
    - In place of an opener icon for leaf nodes, next to the leaf icon
    - As a standalone vertical continuation line in the indent to the left of the node, to show a connection between some ancestor node's siblings (only relevant if `showFullConnectors` is true).
    Note that `showFullConnectors` governs whether connector lines will be displayed for all indent levels, or just for the innermost level of the tree.

    When set to an `SCImgURL`: the stateful filenames for these icons are assembled from this base filename and the state of the node. Assuming the connectorImage is set to `{baseName}.{extension}`, the full set of images to be displayed will be:

    `{baseName}_ancestor[_rtl].{extension}` if `showFullConnectors` is true, this is the URL for the vertical continuation image to be displayed at the appropriate indent levels for ancestor nodes with subsequent children.

    For nodes with no children:

    - `{baseName}_single[_rtl].{extension}`: Shown when there is no connector line attached to the parent or previous sibling, and no connector line to the next sibling. For `showFullConnectors:true` trees, there will always be a connector leading to the parent or previous sibling if its present in the tree so this icon can only be displayed for the first row.
    - `{baseName}_start[_rtl].{extension}`: Shown when the there is no connector line attached to the parent or previous sibling, but there is a connector to the next sibling. As with `_single` this will only ever be used for the first row if `showFullConnectors` is true
    - `{baseName}_end[_rtl].{extension}`: Shown if we are not showing a connector line attached to the next sibling of this node (but are showing a connection to the previous sibling or parent).
    - `{baseName}_middle[_rtl].{extension}`: Shown where the we have a connector line leading to both the previous sibling (or parent) and the next sibling.
    For folders with children. Note that if `showFullConnectors` is false, open folders will never show a connector to subsequent siblings:
    - `{baseName}_opened_single[_rtl].{extension}` opened folder node with children when no connector line is shown attaching to either the folder's previous sibling or parent, or to any subsequent siblings.
    - `{baseName}_opened_start[_rtl].{extension}`: opened folder with children when the there is no connector line attached to the parent or previous sibling, but there is a connector to the next sibling.
    - `{baseName}_opened_end[_rtl].{extension}`: opened folder with children if we are not showing a connector line attached to the next sibling of this node (but are showing a connection to the previous sibling or parent).
    - `{baseName}_opened_middle[_rtl].{extension}`: opened folder with children where the we have a connector line leading to both the previous sibling (or parent) and the next sibling.
    - `{baseName}_closed_single[_rtl].{extension}` closed folder node with children when no connector line is shown attaching to either the folder's previous sibling or parent, or to any subsequent siblings.
    - `{baseName}_closed_start[_rtl].{extension}`: closed folder with children when the there is no connector line attached to the parent or previous sibling, but there is a connector to the next sibling.
    - `{baseName}_closed_end[_rtl].{extension}`: closed folder with children if we are not showing a connector line attached to the next sibling of this node (but are showing a connection to the previous sibling or parent).
    - `{baseName}_closed_middle[_rtl].{extension}`: closed folder with children where the we have a connector line leading to both the previous sibling (or parent) and the next sibling.
    (Note '[_rtl]' means that "_rtl" will be attached if isRTL() is true for this widget).

    If `showSelectedOpener` is true the URL for selected nodes will append the string `"_selected"` to the image URLs described above. So for a connectorImage set to `{baseName}.{extension}`, the URLs for selected records would be `{baseName}_ancestor[_rtl]_selected.{extension}`, `{baseName}_single[_rtl]_selected.{extension}`, etc.

    When set to an SCStatefulImgConfig</>: it should contain entries for the default _base state, as well as the custom states listed above. These entries may be set to any combination of supported src strings, including file-paths and sprite-strings.

  - ### setCreateDefaultTreeField

    public TreeGrid setCreateDefaultTreeField(Boolean createDefaultTreeField) throws IllegalStateException
    If no fields are specified, create a single field with `TreeGridField.treeField` set to `true` to show the tree.

    This automatically generated field will display values derived by calling `getNodeTitle()`, and have the column title set to the specified `treeFieldTitle`.

    Has no effect if fields are explicitly specified.

    This is a convenience setting to allow a TreeGrid to be created without specifying a field list.

    For databound treeGrids, if there is no explicit fields array specified, developers who wish to pick up all fields from the DataSource definition rather than displaying this single automatically generated tree field may either set this property to false, or set `useAllDataSourceFields` to `true`.

    Parameters:
      `createDefaultTreeField` - New createDefaultTreeField value. Default value is true
    Returns:
      `TreeGrid` instance, for chaining setter calls

  - ### setDataFetchMode

    public TreeGrid setDataFetchMode(FetchMode dataFetchMode) throws IllegalStateException
    Mode of fetching records from server.

    fetchMode:"local" implies that local filtering will always be performed. See `keepParentsOnFilter` for additional filtering details.

    fetchMode:"basic" or "paged" implies that if search criteria change, the entire tree will be discarded and re-fetched from the server. When retrieving the replacement tree data, the default behavior will be to preserve the `openState` for any nodes that the server returns which were previously opened by the user. Note that this implies that if `loadDataOnDemand` is enabled and the server returns only root-level nodes, open state will be preserved only for root-level nodes, and children of open root-level nodes will be immediately fetched from the server if they are not included in the server's initial response.

    fetchMode:"paged" enables paging for nodes that have very large numbers of children. Whenever the children of a folder are loaded, the `resultTree` will set `DSRequest.startRow` and `endRow` when requesting children from the DataSource, and will manage loading of further children on demand, similar to how a `ResultSet` manages paging for lists. For a deeper discussion see the Paging large sets of children section of the `TreeDataBinding` overview.

    Specified by:
      `setDataFetchMode` in interface `DataBoundComponent`
    Overrides:
      `setDataFetchMode` in class `ListGrid`
    Parameters:
      `dataFetchMode` - New dataFetchMode value. Default value is "basic"

  - ### setKeepParentsOnFilter

    public TreeGrid setKeepParentsOnFilter(Boolean keepParentsOnFilter) throws IllegalStateException
    If set, tree-based filtering is performed such that parent nodes are kept as long as they have children that match the filter criteria, even if the parents themselves do not match the filter criteria. If not set, filtering will exclude parent nodes not matching the criteria, and all nodes below them in the tree.

    ResultTrees will default to `fetchMode:"local"` whenever `keepParentsOnFilter` is true, unless fetchMode was explicitly set to "paged" (see below). This allows the filtering logic to fetch a complete tree of nodes from the DataSource (or if loadDataOnDemand:true, a complete set of nodes under a given parent) and then filter the resulting data locally on the client.

    This means that the server does not need to implement special tree filtering logic to support looking up nodes that match the specified criteria as well as ancestor nodes that may not.

    If some criteria must be sent to the server in order to produce a valid tree of data, but `keepParentsOnFilter` is also required, the `ResultTree.serverFilterFields` attribute may be used to specify a list of field names that will be sent to the server whenever they are present in the criteria. Note that for the subset of criteria applied to these fields, `keepParentsInFilter` behavior will not occur without custom logic in the DataSource fetch operation.

    If `FetchMode` is explicitly set to `"paged"`, it is not possible to implement `keepParentsOnFilter`, either by local filtering or with the automatic client-driven handling mentioned below. Support for `keepParentsOnFilter` for a paged ResultTree therefore also requires custom logic in the DataSource fetch operation. To support this a developer must ensure that their fetch operation returns the appropriate set of nodes - all nodes that match the specified criteria plus their ancestor nodes even if they do not match the specified criteria.

    ### keepParentsOnFilter with load-on-demand trees

    The combination of `keepParentsOnFilter` and `loadDataOnDemand` presents additional difficulties that require special handling. The problem is that in order to determine even the top-level folders, you have to examine every node in the entire tree. For example, say there is one top-level folder that has thousands of folders and nodes underneath it, and there is just one leaf node, 6 levels deep, that matches the filter criteria. You have to find out about that node, because it implies the top-level folder must be retained.

    So the server basically has to examine every node in the dataset to determine even what shows up at the top level of the tree. If it does not do this, parent nodes that don't match the filter criteria will be excluded from the tree, with the upshot that the child nodes that do match the criteria will be inaccessible because nodes in load-on-demand trees are only loaded when their parent node is opened

    By default, Smart GWT solves this with a client-driven implementation of this special handling. This algorithm involves finding the nodes that match the filter criteria - which we term matching leaves - and then recursively travelling back up the tree, determining the ancestors of the matching leaves - the so-called dangling parents. When we have traversed all the way back to the root node from every matching leaf, we have recorded every dangling parent and have what we term the skeleton of the tree. The skeleton is then added to fetch criteria whenever a load-on-demand fetch request is made, ensuring that we fetch both dangling parents and matching leaves.

    There are three ways this recursive traversal can be implemented:

    - For dataSources that `support dynamic tree joins`, we use the `additionalOutputs` feature to declare self-joins that fetch multiple levels of parent in one query (the number of levels is configurable, see `ResultTree.matchingLeafJoinDepth`). Of Smart GWT's built-in DataSource types, only SQLDataSource is currently capable of this approach
    - For server-side dataSources that do not support self-joins, we combine individual single-level fetches into a `queue`, using `fieldValueExpressions` with `responseData "allRecords"` so that each fetch in the queue uses the output of the previous fetch as its criteria (so the first fetch returns the parents of the matching nodes, the second fetch returns the parents of those nodes, and so on). Again, the number of fetches per queue can be configured with the `matchingLeafJoinDepth` property. This approach works for any server-side DataSource implementation, including your own custom implementations
    - For `client-side` dataSources, which support neither self-joins not queueing, the algorithm simply makes as many single-level requests as necessary to build the entire skeleton. Note, this is exactly what would happen with previously-mentioned queueing approach, if you set `matchingLeafJoinDepth` to 1
    If you want to disable the automatic handling of `keepParentsOnFilter` on load-on-demand trees, see `ResultTree.serverKeepParentsOnFilter`
    Parameters:
      `keepParentsOnFilter` - New keepParentsOnFilter value. Default value is null
    Returns:
      `TreeGrid` instance, for chaining setter calls
    Throws:
      `IllegalStateException` - this property cannot be changed after the component has been created

  - ### setOpenerImage

    public TreeGrid setOpenerImage(String openerImage) throws IllegalStateException
    The base filename or `stateful image block` for the opener icon for folder nodes when "showConnectors" is false for this TreeGrid. The opener icon is displayed beside the folder icon in the Tree column for folder nodes. Clicking on this icon will toggle the open state of the folder.

    When set to an `SCImgURL`: the stateful filenames for these icons are assembled from this base filename and the state of the node, as follows: If the openerImage is set to `{baseName}.{extension}`, `{baseName}_opened.{extension}` will be displayed next to opened folders, and `{baseName}_closed.{extension}` will be displayed next to closed folders, or if this page is in RTL mode, `{baseName}_opened_rtl.{extension}` and `{baseName}_closed_rtl.{extension}` will be used.

    If `showSelectedOpener` is true the URL for selected nodes will append the string `"_selected"` to the image URLs described above. So for an openerImage set to `{baseName}.{extension}`, the URLs for selected records would be `{baseName}_opened_selected.{extension}`, `{baseName}_closed_selected.{extension}`, etc.

    When set to an SCStatefulImgConfig</>: it should contain entries for the default _base state, as well as the custom states: opened, closed, opened_selected and closed_selected (RTL styles are also available, see above). These entries may be set to any combination of supported src strings, including file-paths and sprite-strings.

    The following code shows using `SVG Symbols` from a sprite-file:

           openerImage: {
               // _base state is required, although will not be displayed in this case
               _base: "sprite:svg:fileName.svg#arrowRight;size:12,12;",
               // closed and closed_selected states - make the selected icon blue
               closed: "sprite:svg:fileName.svg#arrowRight;size:12,12;",
               closed_selected: "sprite:svg:fileName.svg#arrowRight;size:12,12;color:blue;",
               // opened and opened_selected states - make the selected icon blue
               opened: "sprite:svg:fileName.svg#arrowDown;size:12,12;",
               opened_selected: "sprite:svg:fileName.svg#arrowDown;size:12,12;color:blue;"
           }

    Parameters:
      `openerImage` - New openerImage value. Default value is "[SKIN]opener.gif"
    Returns:
      `TreeGrid` instance, for chaining setter calls
    Throws:

  - ### getOpenerImageAsSCStatefulImgConfig

    public SCStatefulImgConfig getOpenerImageAsSCStatefulImgConfig()
    The base filename or `stateful image block` for the opener icon for folder nodes when "showConnectors" is false for this TreeGrid. The opener icon is displayed beside the folder icon in the Tree column for folder nodes. Clicking on this icon will toggle the open state of the folder.

    When set to an `SCImgURL`: the stateful filenames for these icons are assembled from this base filename and the state of the node, as follows: If the openerImage is set to `{baseName}.{extension}`, `{baseName}_opened.{extension}` will be displayed next to opened folders, and `{baseName}_closed.{extension}` will be displayed next to closed folders, or if this page is in RTL mode, `{baseName}_opened_rtl.{extension}` and `{baseName}_closed_rtl.{extension}` will be used.

    If `showSelectedOpener` is true the URL for selected nodes will append the string `"_selected"` to the image URLs described above. So for an openerImage set to `{baseName}.{extension}`, the URLs for selected records would be `{baseName}_opened_selected.{extension}`, `{baseName}_closed_selected.{extension}`, etc.

    When set to an SCStatefulImgConfig</>: it should contain entries for the default _base state, as well as the custom states: opened, closed, opened_selected and closed_selected (RTL styles are also available, see above). These entries may be set to any combination of supported src strings, including file-paths and sprite-strings.

    The following code shows using `SVG Symbols` from a sprite-file:

           openerImage: {
               // _base state is required, although will not be displayed in this case
               _base: "sprite:svg:fileName.svg#arrowRight;size:12,12;",
               // closed and closed_selected states - make the selected icon blue
               closed: "sprite:svg:fileName.svg#arrowRight;size:12,12;",
               closed_selected: "sprite:svg:fileName.svg#arrowRight;size:12,12;color:blue;",
               // opened and opened_selected states - make the selected icon blue
               opened: "sprite:svg:fileName.svg#arrowDown;size:12,12;",
               opened_selected: "sprite:svg:fileName.svg#arrowDown;size:12,12;color:blue;"

  - ### setShowOpener

    public TreeGrid setShowOpener(Boolean showOpener)
    Should the opener icon be displayed next to folder nodes? This is an icon which visually indicates whether the folder is opened or closed (typically via a [+] or [-] image, or a turn-down arrow) and may be clicked to expand or collapse the folder.

    For folders with no children, this icon is not shown unless `alwaysShowOpener` is `true`. Note that for trees which `load data on demand`, we may not know if a folder has any descendants if it has never been opened. As such we will show the opener icon next to the folder. Once the user opens the icon and a fetch occurs, if the folder is empty, and `alwaysShowOpener` is false, the opener icon will be hidden.

    For more information on load on demand trees, and how we determine whether a node is a a folder or a leaf, please refer to the `TreeDataBinding` documentation.

    The opener icon URL is derived from the specified `openerImage` or `connectorImage` depending on `showConnectors`. If `showSelectedOpener` is specified a separate opener icon will be displayed for selected nodes.

    Parameters:
      `showOpener` - New showOpener value. Default value is true
    Returns:
      `TreeGrid` instance, for chaining setter calls

  - ### getShowOpener

    If true, show a different icon for `open` folders than closed folders. This is achieved by appending the `openIconSuffix` onto the `folderIcon` URL [for example `"[SKIN]/folder.gif"` might be replaced by `"[SKIN]/folder_open.gif"`.
    Note If this property is set to `false` the same icon is shown for open folders as for closed folders, unless a custom folder icon was specified. This will be determined by `folderIcon` plus the `closedIconSuffix`.
    Returns:
      Current showOpenIcons value. Default value is true
    See Also:
      - Node Titles Example

  - ### setShowPartialSelection

      `setShowPartialSelection` in class `ListGrid`
    Parameters:
      `showPartialSelection` - New showPartialSelection value. Default value is false
    Returns:
      `TreeGrid` instance, for chaining setter calls
    See Also:
      - `Selection`

  - ### getShowPartialSelection

    public Boolean getShowPartialSelection()

      Current showPartialSelection value. Default value is false
    See Also:
      - `Selection`

  - ### setShowRoot

    public TreeGrid setShowRoot(Boolean showRoot) throws IllegalStateException
    Specifies whether the root node should be displayed in the treeGrid.

    This property is only available for "children" modelType trees, hence is not allowed for trees that load data from the server dynamically via `fetchData()`.

    To get the equivalent of a visible "root" node in a tree that loads data dynamically, add a singular, top-level parent to the data. However, note that this top-level parent will technically be the only child of root, and the implicit root object will be returned by `this.data.getRoot()`.

    Parameters:
      `showRoot` - New showRoot value. Default value is false
    Returns:
      `TreeGrid` instance, for chaining setter calls
    Throws:
      `IllegalStateException` - this property cannot be changed after the component has been created

  - ### getShowRoot

    public Boolean getShowRoot()
    Specifies whether the root node should be displayed in the treeGrid.

    This property is only available for "children" modelType trees, hence is not allowed for trees that load data from the server dynamically via `fetchData()`.

    Returns:
      Current showRoot value. Default value is false

  - ### setShowSelectedIcons

    public TreeGrid setShowSelectedIcons(Boolean showSelectedIcons)
    If true, show a different icon for selected nodes than unselected nodes. This is achieved by appending the `selectedIconSuffix` onto the `folderIcon` URL or `nodeIcon` for selected records.

    If appropriate, this suffix will be combined with the `openIconSuffix` or `closedIconSuffix` (see `showOpenIcons`. So a treeGrid with its `folderIcon` property set to `"[SKIN]/folder.gif"`, with both `showSelectedIcons` and `showOpenIcons` set to true would show an icon with the URL `"[SKIN]/folder_open_selected.gif"` for a folder that was both selected and opened.

    Parameters:
      `showSelectedIcons` - New showSelectedIcons value. Default value is false
    Returns:
      `TreeGrid` instance, for chaining setter calls

  - ### getShowSelectedIcons

    If true, show a different icon for selected nodes than unselected nodes. This is achieved by appending the `selectedIconSuffix` onto the `folderIcon` URL or `nodeIcon` for selected records.

    If appropriate, this suffix will be combined with the `openIconSuffix` or `closedIconSuffix` (see `showOpenIcons`. So a treeGrid with its `folderIcon` property set to `"[SKIN]/folder.gif"`, with both `showSelectedIcons` and `showOpenIcons` set to true would show an icon with the URL `"[SKIN]/folder_open_selected.gif"` for a folder that was both selected and opened.

    Returns:
      Current showSelectedIcons value. Default value is false

  - ### setShowSelectedOpener

    public TreeGrid setShowSelectedOpener(Boolean showSelectedOpener)
    If `showOpener` is true, should a different opener icon be displayed for selected nodes? This provides a way for developers to show a "selected" version of the opener icon set which looks optimal with the `selected appearance` applied the selected record.

    The selected icon URL is created by appending the suffix `"_selected"` to the `openerImage` or `connectorImage`.

    Parameters:
      `showSelectedOpener` - New showSelectedOpener value. Default value is false
    Returns:
      `TreeGrid` instance, for chaining setter calls

  - ### getShowSelectedOpener

    public Boolean getShowSelectedOpener()
    If `showOpener` is true, should a different opener icon be displayed for selected nodes? This provides a way for developers to show a "selected" version of the opener icon set which looks optimal with the `selected appearance` applied the selected record.

    The selected icon URL is created by appending the suffix `"_selected"` to the `openerImage` or `connectorImage`.

    Returns:
      Current showSelectedOpener value. Default value is false

  - ### setSortFoldersBeforeLeaves

    public TreeGrid setSortFoldersBeforeLeaves(Boolean sortFoldersBeforeLeaves) throws IllegalStateException
    If specified, this attribute will override `Tree.sortFoldersBeforeLeaves` on the data for this treeGrid.

    Specifies whether when `Tree.separateFolders` is true, folders should be displayed before or after their sibling leaves in a sorted tree. If set to true, with sortDirection set to Array.ASCENDING, folders are displayed before their sibling leaves and with sort direction set to Array.DESCENDING they are displayed after. To invert this behavior, set this property to false.

    Parameters:
      `sortFoldersBeforeLeaves` - New sortFoldersBeforeLeaves value. Default value is null
    Returns:
      `TreeGrid` instance, for chaining setter calls
    Throws:
      `IllegalStateException` - this property cannot be changed after the component has been created
    See Also:

  - ### getSortFoldersBeforeLeaves

    public Boolean getSortFoldersBeforeLeaves()
    If specified, this attribute will override `Tree.sortFoldersBeforeLeaves` on the data for this treeGrid.

    Specifies whether when `Tree.separateFolders` is true, folders should be displayed before or after their sibling leaves in a sorted tree. If set to true, with sortDirection set to Array.ASCENDING, folders are displayed before their sibling leaves and with sort direction set to Array.DESCENDING they are displayed after.

  - ### setUseAllDataSourceFields

    public TreeGrid setUseAllDataSourceFields(Boolean useAllDataSourceFields)
    If true, the set of fields given by the "default binding" (see `DataBoundComponent.fields`) is used, with any fields specified in `component.fields` acting as overrides that can suppress or modify the display of individual fields, without having to list the entire set of fields that should be shown.

    If `component.fields` contains fields that are not found in the DataSource, they will be shown after the most recently referred to DataSource field. If the new fields appear first, they will be shown first.

    This example shows a mixture of component fields and DataSource fields, and how they interact for validation.

    This setting may be cleared if a `FieldPicker` is used to edit the component's field order.

    Specified by:
      `setUseAllDataSourceFields` in interface `DataBoundComponent`

      - `FolderClosedEvent`

  - ### addDataArrivedHandler

    public HandlerRegistration addDataArrivedHandler(DataArrivedHandler handler)
    Add a dataArrived handler.

    Notification method fired whenever this TreeGrid receives new data nodes from the dataSource. Only applies to databound TreeGrids where `TreeGrid.data` is a `ResultTree` - either explicitly created and applied via `TreeGrid.setData()` or automatically generated via a `fetchData()` call.

    Note that `dataArrived()`, unlike `TreeGrid.dataChanged()`, only fires in limited circumstances - when data for a `ResultTree` arrives from the server due to a fetch or cache invalidation, or as a result of filtering. If you want to catch all data changes, you should instead react to `TreeGrid.dataChanged()`.

    Specified by:
      `addDataArrivedHandler` in interface `HasDataArrivedHandlers`
    Parameters:
      `handler` - the dataArrived handler
    Returns:
      `HandlerRegistration` used to remove this handler

  - ### addDataChangedHandler

    public HandlerRegistration addDataChangedHandler(DataChangedHandler handler)
    Add a dataChanged handler.

    Notification method fired when the TreeGrid's data changes, for any reason.

    Examples of why data changed might be:

    - a call to `addData()`, `updateData()`, or `removeData()`
    - `DataSource` updates from the server for `ResultTree` data (triggered by record editing, etc.)
    - fetches arriving back from the server for `ResultTree` data
    - programmatic changes to `Tree` data if made through APIs such as `Tree.add()`, `Tree.remove()`, etc.
    - cache invalidation
    - filtering
    Calling `TreeGrid.setData()` doesn't call this notification directly, but it may fire if one of the above listed events is triggered (e.g. a server fetch for `ResultTree` data).

    Note that the `operationType` parameter is optional and will be passed and contain the operation (e.g. "update") if this notification was triggered by a fetch, an `addData()`, `updateData()`, or `removeData()`, or a `DataSource` update for `ResultTree` data (the first three reasons listed above) but otherwise will be null.

    Specified by:
      `addDataChangedHandler` in interface `HasDataChangedHandlers`
    Parameters:
      `handler` - the dataChanged handler
    Returns:
      `HandlerRegistration` used to remove this handler

  - ### exportClientData

    public void exportClientData()
    Exports this component's data with client-side formatters applied, so is suitable for direct display to users. See `ListGrid.exportClientData()` for details of the general requirements and restrictions when exporting client data.

    The following notes apply when exporting client data from TreeGrids:

    - Export only works correctly if you specify `fields`; if you allow it to generate a `default field`, nothing will be exported
    - Only visible nodes are exported; if you close a node, its children are not exported even if they are loaded and known to the client
    - Tree nodes are exported as a flat list, in the same order they are displayed in the TreeGrid

    If your TreeGrid has custom formatters, formatted values will be exported by default, with HTML normalized to text where possible. Since some levels of HTML normalizing aren't possible, this may result in missing or incorrect export values. In this case, you have two possible approaches:

    - Set `exportRawValues` on the field. This will export the raw underlying value of the field; your formatter will not be called
    - Have your formatter call `isExportingClientData()` and perform whatever alternative formatting you require if that method returns true
    Overrides:
      `exportClientData` in class `ListGrid`
    See Also:
      - `ListGrid.exportClientData()`

  - ### exportClientData

    public void exportClientData(DSRequest requestProperties)

    Overrides:
      `exportClientData` in class `ListGrid`

  - ### exportClientData

    public void exportClientData(DSRequest requestProperties, RPCCallback callback)
    Exports this component's data with client-side formatters applied, so is suitable for direct display to users. See `ListGrid.exportClientData()` for details of the general requirements and restrictions when exporting client data.

    The following notes apply when exporting client data from TreeGrids:

    - Export only works correctly if you specify `fields`; if you allow it to generate a `default field`, nothing will be exported
    - Only visible nodes are exported; if you close a node, its children are not exported even if they are loaded and known to the client
    - Tree nodes are exported as a flat list, in the same order they are displayed in the TreeGrid

    If your TreeGrid has custom formatters, formatted values will be exported by default, with HTML normalized to text where possible. Since some levels of HTML normalizing aren't possible, this may result in missing or incorrect export values. In this case, you have two possible approaches:

    - Set `exportRawValues` on the field. This will export the raw underlying value of the field; your formatter will not be called
    - Have your formatter call `isExportingClientData()` and perform whatever alternative formatting you require if that method returns true
    Overrides:
      `exportClientData` in class `ListGrid`
    Parameters:
      `requestProperties` - Request properties for the export. Note that specifying `exportData` on the request properties allows the developer to pass in an explicit data set to export.
      `callback` - Optional callback. If you specify `exportToClient`: false in the request properties, this callback will fire after export completes. Otherwise the callback will fire right before the download request is made to the server.

Note that if you set up a callback for `nodeContextClick()` and e.g. `TreeGrid.leafContextClick()`, then both will fire (in that order) if a leaf is contextclicked - unless `nodeContextClick()` returns false, in which case no further contextClick callbacks will be called.

    Specified by:
      `addNodeContextClickHandler` in interface `HasNodeContextClickHandlers`
    Parameters:
      `handler` - the nodeContextClick handler
    Returns:
      `HandlerRegistration` used to remove this handler

  - ### addFolderDropHandler

    public HandlerRegistration addFolderDropHandler(FolderDropHandler handler)
    Add a folderDrop handler.

    Process a drop of one or more nodes on a TreeGrid folder.
    Note: See `TreeGridDrop` for an overview of TreeGrid drag and drop behavior. Add logic in your drop handler to perform custom drop behaviors; to suppress the built-in behavior described below, use `event.cancel()`

    The default behavior is to simply delegate to the `TreeGrid.transferNodes()` method; thus, the correct way to perform a programmatic folder drop, with all the built-in behaviors described below, is to call `transferNodes()`

    If this is a self-drop, nodes are simply reordered. An "update" operation will be submitted to update the `parentId` field of the moved node(s).

    For a drop from another widget, `TreeGrid.transferDragData()` is called which, depending on the `dragDataAction` specified on the source widget, may either remove the source nodes from the original list (`dragDataAction:"move"`) or just provide a copy to this tree (`dragDataAction:"copy"`).

    In either case the new row(s) appear in the `folder` at the `index` specified by the arguments of the same name.

    If this grid is databound, the new nodes will be added to the dataset by calling `DataSource.addData()`. Further, if the new nodes were dragged from another databound component, and `addDropValues` is true, `getDropValues` will be called for every item being dropped.

    As a special case, if the `sourceWidget` is also databound and a `foreignKey` relationship is declared from the `sourceWidget`'s DataSource to this TreeGrid's DataSource, the interaction will be treated as a "drag recategorization" use case such as files being placed in folders, employees being assigned to teams, etc. "update" DSRequests will be submitted that change the foreignKey field in the dropped records to point to the tree folder that was the target of the drop. In this case no change will be made to the Tree data as such, only to the dropped records.

    For multi-record drops, Queuing is automatically used to combine all DSRequests into a single HTTP Request (see QuickStart Guide, Server Framework chapter). This allows the server to persist all changes caused by the drop in a single transaction (and this is automatically done when using the built-in server DataSources with Power Edition and above).

    If these default persistence behaviors are undesirable, use `event.cancel()`, then implement your own behavior, typically by using grid.updateData() or addData() to add new records.

    NOTE: the records you receive in this event are the actual Records from the source component. Use `DataSource.copyRecords()` to create a copy before modifying the records or using them with updateData() or addData().

    Specified by:
      `addFolderDropHandler` in interface `HasFolderDropHandlers`
    Parameters:
      `handler` - the folderDrop handler
    Returns:
      `HandlerRegistration` used to remove this handler

  - ### setDefaultProperties

    public static void setDefaultProperties(TreeGrid treeGridProperties)
    Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

    Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

    Parameters:
      `treeGridProperties` - properties that should be used as new defaults when instances of this class are created
    See Also:
      - `SGWTProperties`

  - ### onInit

    protected void onInit()
    Overrides:
      `onInit` in class `ListGrid`

  - ### startEditingNew

    public void startEditingNew()
    This inherited `ListGrid API` is not supported by the TreeGrid since adding a new tree node arbitrarily at the end of the tree is usually not useful. Instead, to add a new tree node and begin editing it, use either of these two strategies:
    1. add a new node to the client-side Tree model via `Tree.add`, then use `startEditing` to begin editing this node. Note that if using a DataSource, when the node is saved, an "update" operation will be used since adding a node directly to the client-side `ResultTree` effectively means a new node has been added server side.
    2. use `DataSource.addData` to immediately save a new node. Automatic cache sync by the `ResultTree` will cause the node to be integrated into the tree. When the callback to addData() fires, locate the new node by matching primary key and call `startEditing` to begin editing it.
    Overrides:
      `startEditingNew` in class `ListGrid`
    See Also:
      - `ListGrid.startEditing()`
      - `Grid Editing`

  - ### getNodeTitle

    protected String getNodeTitle(Record node, int recordNum, ListGridField field)
    &#010 Returns the title to show for a node in the tree column. If the field specifies the&#010 `name` attribute, then the current `node[field.name]` is returned.&#010 Otherwise, the result of calling `Tree.getTitle(com.smartgwt.client.widgets.tree.TreeNode)` on the node is called.&#010
    &#010 You can override this method to return a custom title for node titles in the tree column.&#010&#010 Note : This is an override point
    Parameters:
      `node` - The node for which the title is being requested.
      `recordNum` - The index of the node.
      `field` - The field for which the title is being requested.
    Returns:
      the title to display.

  - ### getIcon

    protected String getIcon(Record node, boolean defaultState)
    Get the appropriate icon for a node.&#010

    &#010 By default icons are derived from `folderIcon` and `nodeIcon`.&#010 Custom icons for individual nodes can be overridden by setting the `customIconProperty`&#010 on a node.&#010

    &#010 If you want to suppress icons altogether, provide an override of this method that simply&#010 returns null.&#010

    &#010 Note that the full icon URL will be derived by applying `Canvas.getImgURL(java.lang.String)` to the&#010 value returned from this method.&#010&#010

    Note: This is an override point

    Parameters:
      `node` - tree node in question
      `defaultState` - defaultState
    Returns:
      URL for icon to show for this node

  - ### setCustomNodeIcon

    public void setCustomNodeIcon(Record node, String icon)
    Set the icon for a particular TreeNode to a specified URL
    Parameters:
      `node` - the tree node
      `icon` - path to the resource

  - ### getExtraIcon

    public String getExtraIcon(TreeNode node)
    Get an additional icon to show between the open icon and folder/node icon for a particular node.

    NOTE: If `selectionAppearance` is `"checkbox"`, this method will NOT be called. Extra icons cannot be shown for that appearance.

    Note: This is an override point

    Parameters:
      `node` - tree node in question
    Returns:
      URL for the extra icon (null if none required). See `TreeNode`

  - ### getDropFolder

    public TreeNode getDropFolder()
    When the user is dragging a droppable element over this grid, this method returns the folder&#010 which would contain the item if dropped. This is the current drop node if the user is hovering&#010 over a folder, or the node's parent if the user is hovering over a leaf.&#010
    Returns:
      target drop folder

  - ### setData

    public void setData(Tree data)
    A `Tree` object containing of nested `TreeNode`s to display as rows in this TreeGrid. The `data` property will typically not be explicitly specified for databound TreeGrids, where the data is returned from the server via databound component methods such as `fetchData()`
    If this method is called after the component has been drawn/initialized: Set the `Tree` object this TreeGrid will view and manipulate.
    Parameters:
      `data` - Tree to show. Default value is null

  - ### getData

    public Tree getData()
    A `Tree` object containing of nested `TreeNode`s to display as rows in this TreeGrid. The `data` property will typically not be explicitly specified for databound TreeGrids, where the data is returned from the server via databound component methods such as `fetchData()`
    Returns:
      Tree

  - ### getTree

    public Tree getTree()
    Synonym for `getData()`
    Returns:
      the underlying tree

  - ### setDataProperties

    public void setDataProperties(Tree resultTreeProperties)
    For databound TreeGrids, this attribute can be used to customize the `com.smartgwt.client.tree.ResultTree` object created for this grid when data is fetched.

    Note : This is an advanced setting

    Class overrides for `ResultTree` cannot be applied to the grid using this API. Instead, consider setting the `resultTreeClass` property in the file defining your `DataSource`. Your class must be `registered for reflection`.
    Parameters:
      `resultTreeProperties` - the data properties
    See Also:
      - `Databinding overview and related methods`

  - ### getRecords

    public ListGridRecord[] getRecords()
    Return the tree nodes as a flat array of ListGridRecords. Internally this method retrieves all the nodes via `Tree.getOpenList(TreeNode)`. You should favor working with the underlying `Tree` data structure when working with a TreeGrid.
    Overrides:
      `getRecords` in class `ListGrid`
    Returns:
      the tree nodes as ListGridRecord's

  - ### setInitialData

    public void setInitialData(TreeNode[] initialData) throws IllegalStateException
    You can specify the initial set of data for a databound TreeGrid using this property. The value of this attribute should be a list of `parentId`-linked `TreeNode`s in a format equivalent to that documented on `Tree.data` or, for TreeGrids with `dataFetchMode` set to `"paged"`, on `ResultTree.data`.

    If you create a standalone `Tree` or `ResultTree` as the TreeGrid's `data` then you may equivalently specify this initial set of tree nodes in that tree's `data` property.

    Note : This is an advanced setting

    Parameters:
      `initialData` - New initialData value. Default value is null
    Throws:
      `IllegalStateException` - this property cannot be changed after the component has been created
    See Also:
      - `TreeNode`
      - `Tree.setData(com.smartgwt.client.widgets.tree.TreeNode[])`

  - ### fetchData

    public void fetchData()
    Uses a "fetch" operation on the current `DataSource` to retrieve data that matches the provided criteria, and displays the matching data in this component as a tree.

    This method will create a `com.smartgwt.client.data.ResultTree` to manage tree data, which will subsequently be available as `treeGrid.data`. DataSource records returned by the "fetch" operation are linked into a tree structure according to `primaryKey` and `foreignKey` declarations on DataSource fields. See the `TreeDataBinding` topic for complete details.

    By default, the created ResultTree will use folder-by-folder load on demand, asking the server for the children of each folder as the user opens it.

    The `com.smartgwt.client.data.ResultTree` created by `fetchData()` can be customized by setting `dataProperties` to an Object containing properties and methods to apply to the created ResultTree. For example, the property that determines whether a node is a folder (`isFolderProperty`) can be customized, or level-by-level loading can be disabled via `loadDataOnDemand`.

    The callback passed to `fetchData` will fire once, the first time that data is loaded from the server. If using folder-by-folder load on demand, use the `com.smartgwt.client.data.ResultTree#dataArrived` notification to be notified each time new nodes are loaded.

    Note that, if criteria are passed to `fetchData()`, they will be passed every time a new "fetch" operation is sent to the server. This allows you to retrieve multiple different tree structures from the same DataSource. However note that the server is expected to always respond with an intact tree - returned nodes which do not have parents are dropped from the dataset and not displayed.

    Specified by:
      `fetchData` in interface `DataBoundComponent`
    Overrides:
      `fetchData` in class `ListGrid`

  - ### fetchData

    public void fetchData(Criteria criteria)

  - ### setTreeRootValue

    public void setTreeRootValue(String treeRootValue) throws IllegalStateException
    For databound trees, use this attribute to supply a `DataSourceField.rootValue` for this component's generated data object.

    This property allows you to have a particular component navigate a tree starting from any given node as the root.

    Note : This is an advanced setting

    Parameters:
      `treeRootValue` - New treeRootValue value. Default value is null
    Throws:

    For databound trees, use this attribute to supply a `DataSourceField.rootValue` for this component's generated data object.

    This property allows you to have a particular component navigate a tree starting from any given node as the root.

    Note : This is an advanced setting

    Parameters:
      `treeRootValue` - New treeRootValue value. Default value is null

    Parameters:
      `record` - this cell's record
      `rowNum` - row number for the cell
      `colNum` - column number of the cell
    Returns:

    public void setCellValueHoverFormatter(CellValueHoverFormatter formatter)
    Description copied from class: `ListGrid`
    Provide a custom implementation of `ListGrid.cellValueHoverHTML(ListGridRecord, int, int, String)`.

    The `CellValueHoverFormatter` should return the HTML to display in the hover canvas that is displayed by default if a registered `CellValueHoverHandler` does not cancel a `CellValueHoverEvent`. The formatter can return null or an empty string to cancel the hover.

    Overrides:
      `setCellValueHoverFormatter` in class `ListGrid`
    Parameters:
      `formatter` - the cell value hover formatter

  - ### willAcceptDrop

    public Boolean willAcceptDrop()
    This method overrides `ListGrid.willAcceptDrop()` and works as follows:
    First, `ListGrid.willAcceptDrop()` (the superclass definition) is consulted. If it returns false, then this method returns false immediately.
    This handles the following cases:
    - reordering of records within this TreeGrid when `canReorderRecords` is true
    - accepting dropped records from another dragTarget when `canAcceptDroppedRecords` is true and the dragTarget gives us a valid set of records to drop into place.
    - disallowing drop over disabled nodes, or nodes with `canAcceptDrop:false`
    This method will also return false if the drop occurred over a leaf node whose immediate parent has `canAcceptDrop` set to `false`
    If `canReparentNodes` is true, and the user is dragging a node from one folder to another, this method will return true to allow the change of parent folder.
    Otherwise this method returns true. Note: This is an override point.
    Overrides:
      `willAcceptDrop` in class `ListGrid`
    Returns:
      true if this component will accept a drop of the dragData

  - ### transferNodes

    public void transferNodes(TreeNode[] nodes, TreeNode folder, Integer index, Canvas sourceWidget, TransferNodesCallback callback)
    Transfer a list of `TreeNode`s from another component (does not have to be a databound component) into this TreeGrid.

    This method implements the automatic drag-copy and drag-move behavior and calling it is equivalent to completing a drag and drop of the nodes (the default folder drop behavior is simply to call `transferNodes()`, passing in the dropped nodes)

    Note that this method is asynchronous - it may need to perform server turnarounds to prevent duplicates in the target component's data. If you wish to be notified when the transfer process has completed, you can either pass a non-null callback to this method or add a `DropCompleteHandler` to this component.

    See also `transferSelectedData()`

    Parameters:
      `nodes` - Nodes to transfer to this component
      `folder` - The target folder (eg, of a drop interaction), for context
      `index` - (Insert point within the target folder data for the transferred nodes
      `sourceWidget` - The databound or non-databound component from which the nodes are to be transferred.
      `callback` - optional TransferNodesCallback to be fired when the transfer process has completed (pass null if your code does not need to be called back). The callback will be passed the list of nodes actually transferred to this component

  - ### addRecordDropHandler

    public HandlerRegistration addRecordDropHandler(RecordDropHandler handler) throws UnsupportedOperationException
    This ListGrid superclass event does not fire on a TreeGrid, use `addFolderDropHandler(com.smartgwt.client.widgets.tree.events.FolderDropHandler)` instead.
    Specified by:
      `addRecordDropHandler` in interface `HasRecordDropHandlers`
    Overrides:
      `addRecordDropHandler` in class `ListGrid`
    Parameters:
      `handler` - the onRecordDrop handler
    Returns:
      `HandlerRegistration` used to remove this handler
    Throws:
      `UnsupportedOperationException`
