Hey all, I'm having a problem here and was wondering if anyone could
shine some light.
I'm trying to find out what EditPart/Figure is under the cursor at any
moment.
Using EditPartViewer.findObjectAt(<point>) gives me back the root edit
part but not the specific edit part.
I've tried using EditPartViewer.findObjectAtExcluding(Point position,
Collection exclusionList, Conditional condition) in both the following
ways to specify I don't want the root edit part:
1) Giving it a List containing the root edit part that I don't want.
2) Using the following Conditional
new EditPartViewer.Conditional() {
public boolean evaluate(EditPart part) {
return part instanceof <type of part I want>;
}
}
But both of them still give me back the root.
Anyone got any ideas? I was thinking of locating the IFigure instead and
working from there, but getLightWeightSystem() is a protected method
in EditPartViewer so I can't access it.
Regards,
Kevin.

Ah found the problem. Forgot to convert the absolute cursor location
into one relevant to the Graphical viewer.
Thanks.
