Interface DynamicCriteria

public interface DynamicCriteria

If a property indicates it has support for "dynamic criteria" it means that values in the criteria may be dynamically derived from the current Canvas.ruleScope using Criterion.valuePath.

In other words, it allows criteria to be declared using values from nearby drawn components, via the Canvas.ruleScope. Values are pulled from the ruleScope via setting Criterion.valuePath When values drawn from the ruleScope change, the component where dynamicCriteria is declared will be notified and automatically use the new value

  public void onModuleLoad() {
 
       TextItem lifeSpan = new TextItem("lifeSpan");
       lifeSpan.setDefaultValue(45);
 
       final DynamicForm theForm = new DynamicForm();
       theForm.setID("theForm");
       theForm.setItems(lifeSpan);
 
       AdvancedCriteria initialCriteria = new AdvancedCriteria("lifeSpan", OperatorId.GREATER_THAN);
       initialCriteria.setValuePath("theForm.values.lifeSpan");
 
       ListGrid lg = new ListGrid();
       lg.setAutoFetchData(true);
       lg.setDataSource(AnimalXmlDS.getInstance());
       lg.setInitialCriteria(initialCriteria);
       lg.setWidth(600); lg.setHeight(400); lg.setTop(50);
 
       VLayout vl = new VLayout();
       vl.addMembers(theForm, lg);
       vl.draw();
  }
