Eclipse4/RCP/Modeled UI/Modifying the Model

The Eclipse 4 application model is backed by interfaces exposing simple POJO methods. Please see below for some sample code.

// change the label of a menu item
menuItem.setLabel("New Name");
 
// mark a part as being dirty
part.setDirty(true);
 
// get a list of child windows
List<MWindow> childWindows = mainWindow.getWindows();

Reparenting an Element

When a drag-and-drop operation has been performed, one part may be moved from one stack to another stack. This can be executed with the code below.

List<MStackElement> children = otherStack.getChildren();
children.add(draggedPart);
