GXT FramedPanel Drag for header

I want include Grid in FramedPanel and using gxt dnd.
But if I add FramedPanel in DragSource:

DragSource source = new DragSource(framedPanel) {
              @Override
              protected void onDragStart(DndDragStartEvent event) {
                super.onDragStart(event);
                event.setData(framedPanel);


              }
            };


DnD works when I click and hold on Grid. How I can do to DnD only worked on the header of FramedPanel.

Consider using Draggable instead of DragSource, then use the constructor that takes two arguments. This way you can specify the header as the 'handle' argument.

Draggable draggable = new Draggable(framedPanel, framedPanel.getHeader());
//assuming GXT 3, just guessing from your post
draggable.addDragStartHandler(new DragStartHandler() {
  public void onDragStart(DragStartEvent event) {
    //...
  }
});

If you must use DragSource, subclass it to replace the Draggable instance, and create a new instance as specified above, plus making the changes found in the existing DragSource constructor.
