Hi,
I am using getWidgetCount() but it does not look like i am getting
correct results. Here is the code where i have this function:
public class ERD1 implements EntryPoint {
private PickupDragController dragController;
final AbsolutePanel boundaryPanel = new AbsolutePanel();
int i;
public void onModuleLoad() {
boundaryPanel.setPixelSize(1000, 1000);
final Diagram d = new Diagram(boundaryPanel);
dragController = new PickupDragController(boundaryPanel,
true);
dragController.setBehaviorMultipleSelection(false);
dragController.setBehaviorDragProxy(false);
dragController.setBehaviorConstrainedToBoundaryPanel(true);
AddDraggableWidget adw = new AddDraggableWidget
(dragController);
adw.add(new CreateClone(new Test()));
adw.add(new CreateClone(new Test2()));
Button b = new Button("Click for Connector");
b.addClickListener(new ClickListener(){
@Override
public void onClick(Widget sender) {
SectionDecoration startDecoration = new
SectionDecoration
(SectionDecoration.DECORATE_ARROW);
SectionDecoration endDecoration = new
SectionDecoration
(SectionDecoration.DECORATE_ARROW);
Connector con = new Connector(250, 30, 300,
100, startDecoration, endDecoration);
con.showOnDiagram(d);
i = boundaryPanel.getWidgetCount();
System.out.println("No of widget" + i);
}
});
boundaryPanel.add(b, 20, 30);
boundaryPanel.add(adw, 20, 60);
RootPanel.get().add(boundaryPanel);
}
}
Here when ever i click on the button i am trying to get the number of
widgets in the panel. The AddDragabbleWidget, CreateClone, Test, and
Test2 are the class that help to create clones of widgets. Test and
Test2 extends composite panels. But first time when i run the program
without creating any clones this is how it looks:
http://www.cs.uofs.edu/~sudhakaras2/one.jpg there are only 6 widgets
but the answer for getWidgetCount() is 10 and when i create clones
this is how it looks: http://www.cs.uofs.edu/~sudhakaras2/two.jpg
there are extra four more widgets but it gives 20 as answer.
Can anyone please point out what the problem is.
Thank you.
