Class ElementTreeViewAdapter

java.lang.Object
oracle.ide.controls.elementtree.ElementTreeViewAdapter

public final class ElementTreeViewAdapter

extends java.lang.Object

This class facilitates the integration of an ElementTree in a View. A typical usage for a view would be to have a private instance:

  private ElementTreeViewAdapter _elementTreeViewAdapter;

That instance is initialized in the getGUI():

 public Component getGUI() {
   if (_ui == null) {
     _elementTreeViewAdapter = new ElementTreeViewAdapter(this, rootElement);
     _ui = _elementTreeViewAdapter.getComponent();
   }
   return _ui;
 }
 

To handle the selection, add the following method to your view:

 protected final Element[] getSelectionFromUI() {
   return _elementTreeViewAdapter.getSelectionFromUI();
 }
