Hi,
Using LogicDnd example as a reference, I wrote a plugin which is somewhat
similar. I have a TreeViewer of objects from which I can drag the object
onto a graphical editor and it will appear in the editor as a UML Class
Figure. I used the standard DragSupport in the TreeViewer and a
AbstractTransferDropTargetListener in the editor. All works well and the
new object gets added as a child to the container which I am editing.
However, although the Model (MVC paradigm) gets updated, and the update is
propagated to the EditPart via PropertyChangeListener, the View does not
get updated instantly. I need to either switch to another view and back,
or minimise the workbench and then restore it, in other words, I have to
somehow force the editor to refresh itself. I know something is wrong with
my code somewhere but I am not sure where to look. I tried using a
refreshVisual() after I called refreshChildren(), but it din work. Please
help. Thanks.
Rgds,
Lee

Hi,
I totally have no clue where the problem could be. And I dun think I can
possibly post the entire plugin here. So I just post a few snippets,
hopefully it shows the problem....
If my children has been changed, I will fire an event...
public void addModel(Model mod) {
this.models.add(mod);
fireStructureChange(CHILDREN, mod);
}
This will be captured by the following method in the EditPart.
public void propertyChange(PropertyChangeEvent arg0) {
// TODO Auto-generated method stub
String propName = arg0.getPropertyName();
if(Entity.CHILDREN.equals(propName))
{
refresh();
}
else
{
System.err.println(this.getClass().getName() + ".propertyChange unknown
propName: " + propName);
}
}
Is there anything else I need to post to be helpful? Thanks...
Rgds,
Lee

Does the same function work in the Logic example? BTW, you can drag and
drop items form the logic palette into the diagram.
I would suggest putting breakpoints in things that you expect to be
happening. Such as Figure.repaint(), DeferredUpdateManager.repairDamage(),
etc.

Hi,
Thanks. I will try doing that first to narrow down my area for debugging.
