  - ### setAutoFit

    public Button setAutoFit(Boolean autoFit)
    If true, ignore the specified size of this widget and always size just large enough to accommodate the title. If `setWidth()` is explicitly called on an autoFit:true button, autoFit will be reset to `false`.

    Note that for StretchImgButton instances, autoFit will occur horizontally only, as unpredictable vertical sizing is likely to distort the media. If you do want vertical auto-fit, this can be achieved by simply setting a small height, and having overflow:"visible"
    If this method is called after the component has been drawn/initialized: Setter method for the `StatefulCanvas.autoFit` property. Pass in true or false to turn autoFit on or off. When autoFit is set to `false`, canvas will be resized to it's previously specified size.

    Overrides:
      `setAutoFit` in class `StatefulCanvas`
    Parameters:
      `autoFit` - New autoFit setting. Default value is null
    Returns:
      `Button` instance, for chaining setter calls

    Returns:
      Current autoFit value. Default value is null
    See Also:
      - `Sizing overview and related methods`
      - Auto Fit Example

  - ### setBaseStyle

    public Button setBaseStyle(String baseStyle)
    Base CSS style className applied to the component.

    Note that if specified, this property takes precedence over any specified `StatefulCanvas.styleName`. If unset, the `styleName` will be used as a default `baseStyle` value.

    As the component changes `StatefulCanvas.state` and/or is selected, suffixes will be added to the base style. In some cases more than one suffix will be appended to reflect a combined state ("Selected" + "Disabled", for example).

    See `StatefulCanvas.getStateSuffix()` for a description of the default set of suffixes which may be applied to the baseStyle

    #### Rotated Titles

    The Framework doesn't have built-in support for rotating button titles in a fashion similar to `FacetChart.rotateLabels`. However, you can manually configure a button to render with a rotated title by applying custom CSS via this property.

    For example, given a button with a height of 120 and a width of 48, if you copied the existing buttonXXX style declarations from skin_styles.css as new, rotatedTitleButtonXXX declarations, and then added the lines:

              -ms-transform:     translate(-38px,0px) rotate(270deg);
              -webkit-transform: translate(-38px,0px) rotate(270deg);
              transform:         translate(-38px,0px) rotate(270deg);
              overflow: hidden;
              text-overflow: ellipsis;
              width:116px;

    in the declaration section beginning:

          .rotatedTitleButton,
          .rotatedTitleButtonSelected,
          .rotatedTitleButtonSelectedOver,
          .rotatedTitleButtonSelectedDown,
          .rotatedTitleButtonSelectedDisabled,
          .rotatedTitleButtonOver,
          .rotatedTitleButtonDown,
          .rotatedTitleButtonDisabled {

    then applying that style to the button with `overflow`: "clip_h" would yield a vertically-rendered title with overflow via ellipsis as expected, and also wrap with `wrap`. Note that:
    - The explicit width applied via CSS is needed because rotated elements don't inherit dimensions in their new orientation from the DOM - the transform/rotation occurs independently of layout.
    - The translation transform required along the x-axis is roughly (width - height) / 2, but may need slight offsetting for optimal centering.
    - We've explicitly avoided describing an approach based on CSS "writing-mode", since support is incomplete and bugs are present in popular browsers such as Firefox and Safari that would prevent it from being used without Framework assistance.

    Note on css-margins: Developers should be aware that the css "margin" property is unreliable for certain subclasses of StatefulCanvas, including `buttons`. Developers may use the explicit `Canvas.margin` property to specify button margins, or for a button within a layout, consider the layout properties `Layout.layoutMargin`, `Layout.membersMargin`
    If this method is called after the component has been drawn/initialized: Sets the base CSS style. As the component changes state and/or is selected, suffixes will be added to the base style.

    Overrides:
      `setBaseStyle` in class `StatefulCanvas`
    Parameters:
      `baseStyle` - new base style. Default value is "button"
    Returns:
      `Button` instance, for chaining setter calls
    See Also:
      - `setIconOnlyBaseStyle(java.lang.String)`
      - `CSSStyleName`

  - ### getBaseStyle

    public String getBaseStyle()
    Base CSS style className applied to the component.

    Note that if specified, this property takes precedence over any specified `StatefulCanvas.styleName`. If unset, the `styleName` will be used as a default `baseStyle` value.

    As the component changes `StatefulCanvas.state` and/or is selected, suffixes will be added to the base style. In some cases more than one suffix will be appended to reflect a combined state ("Selected" + "Disabled", for example).

              transform:         translate(-38px,0px) rotate(270deg);
              overflow: hidden;
              text-overflow: ellipsis;
              width:116px;

    in the declaration section beginning:

          .rotatedTitleButton,
          .rotatedTitleButtonSelected,
          .rotatedTitleButtonSelectedOver,
          .rotatedTitleButtonSelectedDown,
          .rotatedTitleButtonSelectedDisabled,
          .rotatedTitleButtonOver,
          .rotatedTitleButtonDown,
          .rotatedTitleButtonDisabled {

  - ### setCanAdaptWidth

    public Button setCanAdaptWidth(Boolean canAdaptWidth) throws IllegalStateException
    This flag enables `adaptive width` for the button.

    If enabled the button will support rendering in a 'collapsed' view if there isn't enough space in a layout to render it at normal size. There are a couple of ways this can be achieved.

    - If `adaptWidthShowIconOnly` is true and this button shows an icon, the title will be hidden if there isn't enough space to render it, allowing it to shrink to either the rendered icon width, or any specified `minWidth`, whichever is larger.
    - Otherwise, if the button has a specified `minWidth`, and `autoFit` is true, autoFit will be temporarily disabled, if there isn't enough room, allowing the title to be clipped
    In either case the title will show on hover unless an explicit hover has been specified such as by overriding `titleHoverHTML()`.
    Overrides:
      `setCanAdaptWidth` in class `Canvas`
    Parameters:
      `canAdaptWidth` - New canAdaptWidth value. Default value is false

    StatefulCanvases will have a different appearance based on their current state. By default this is handled by changing the css className applied to the StatefulCanvas - see `StatefulCanvas.baseStyle` and `StatefulCanvas.getStateSuffix()` for a description of how this is done.

    For `Img` or `StretchImg` based subclasses of StatefulCanvas, the appearance may also be updated by changing the src of the rendered image. See `Img.src` and `StretchImgButton.src` for a description of how the URL is modified to reflect the state of the widget in this case.
    If this method is called after the component has been drawn/initialized: Sets the `state` of this object, changing its appearance. Note: `newState` cannot be `State.STATE_DISABLED` if `this.showDisabled` is `false`.

    Note : This is an advanced setting

    Current "state" of this widget. The state setting is automatically updated as the user interacts with the component (see `StatefulCanvas.showRollOver`, `StatefulCanvas.showDown`, `StatefulCanvas.showDisabled`).

    StatefulCanvases will have a different appearance based on their current state. By default this is handled by changing the css className applied to the StatefulCanvas - see `StatefulCanvas.baseStyle` and `StatefulCanvas.getStateSuffix()` for a description of how this is done.

    For `Img` or `StretchImg` based subclasses of StatefulCanvas, the appearance may also be updated by changing the src of the rendered image. See `Img.src` and `StretchImgButton.src` for a description of how the URL is modified to reflect the state of the widget in this case.

  - ### setStyleName

    public void setStyleName(String styleName)
    StatefulCanvases are styled by combining `baseStyle` with `State` to build a composite css style name. In most cases, `statefulCanvas.styleName` will have no effect on statefulCanvas styling and should not be used.

    If the `baseStyle` is not explicitly specified for a class, the `styleName` will be used as a default baseStyle. Other than that, this attribute will be ignored.

    Overrides:
      `setStyleName` in class `StatefulCanvas`

    If the `baseStyle` is not explicitly specified for a class, the `styleName` will be used as a default baseStyle. Other than that, this attribute will be ignored.

    Overrides:
      `getStyleName` in class `StatefulCanvas`
    Returns:
      Current styleName value. Default value is "normal"
    See Also:
      - `CSSStyleName`

  - ### setTitle

    public void setTitle(String title)

  - ### setUseSpan

    public Button setUseSpan(Boolean useSpan) throws IllegalStateException
    Controls whether the button title is wrapped in a span element.

    Note: This property only has a visual effect when `supportsCSSAlignment` is true. When supportsCSSAlignment is false (table-based layout), ellipsis display works correctly without a span wrapper.

    When null (default), defaults to true for all overflow modes to preserve ellipsis display behavior. Set explicitly to false to skip the span wrapper for simpler DOM when ellipsis is not needed.

    Why the span matters: CSS text-overflow:ellipsis does NOT visually render on direct text children of flex/grid containers - text is truncated but no "..." shows. The span element is required to display the ellipsis indicator.

    When useSpan is explicitly set to false (and supportsCSSAlignment is true):

    - Overflowing text is truncated but NO ellipsis "..." displays
    - `titleClipped()` returns false
    - `showClippedTitleOnHover` will not trigger
    - Simpler DOM structure with fewer elements

    Note : This is an advanced setting

    Parameters:
      `useSpan` - New useSpan value. Default value is null
    Returns:
      `Button` instance, for chaining setter calls
    Throws:
      `IllegalStateException` - this property cannot be changed after the component has been created
    See Also:
      - `titleClipped()`
      - `setShowClippedTitleOnHover(java.lang.Boolean)`

  - ### getUseSpan

    public Boolean getUseSpan()
    Controls whether the button title is wrapped in a span element.

    Note: This property only has a visual effect when `supportsCSSAlignment` is true. When supportsCSSAlignment is false (table-based layout), ellipsis display works correctly without a span wrapper.

    When null (default), defaults to true for all overflow modes to preserve ellipsis display behavior. Set explicitly to false to skip the span wrapper for simpler DOM when ellipsis is not needed.

    Why the span matters: CSS text-overflow:ellipsis does NOT visually render on direct text children of flex/grid containers - text is truncated but no "..." shows. The span element is required to display the ellipsis indicator.

    When useSpan is explicitly set to false (and supportsCSSAlignment is true):

    - Overflowing text is truncated but NO ellipsis "..." displays
    - `titleClipped()` returns false
    - `showClippedTitleOnHover` will not trigger
    - Simpler DOM structure with fewer elements
    Returns:
      Current useSpan value. Default value is null
    See Also:
      - `titleClipped()`
      - `getShowClippedTitleOnHover()`

  - ### addTitleHoverHandler

    public HandlerRegistration addTitleHoverHandler(TitleHoverHandler handler)
    Add a titleHover handler.

    Optional stringMethod to fire when the user hovers over this button and the title is clipped. If `Button.showClippedTitleOnHover` is true, the default behavior is to show a hover canvas containing the HTML returned by `Button.titleHoverHTML()`. Call `TitleHoverEvent.cancel()` from within `TitleHoverHandler.onTitleHover(com.smartgwt.client.widgets.events.TitleHoverEvent)` to suppress this default behavior.

    Specified by:
      `addTitleHoverHandler` in interface `HasTitleHoverHandlers`
    Parameters:

      - `HTMLString`

  - ### setDefaultProperties

    public static void setDefaultProperties(Button buttonProperties)
    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:
      `buttonProperties` - properties that should be used as new defaults when instances of this class are created
    See Also:
      - `SGWTProperties`

  - ### setTitleHoverFormatter

    public void setTitleHoverFormatter(TitleHoverFormatter formatter)
    Provide a custom implementation of `titleHoverHTML(java.lang.String)`.
