To get the active editor you can use:
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().getActiveEditor()
Now, once you get the active editor you'd want to double check that its
the right one:-)
The count will give you a count of everything, connectors, labels, and
nodes so you might need to filter it down to count the appropriate type.
The following code might give you some hints about what you can access;
I think you can just put it in the run code of your button and execute
it (haven't tried it myself :-)).
Let me know if this is not enough info.
-- Khai --
IEditorPart editorPart =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().getActiveEditor();
if(editorPart instanceof DiagramEditor){
DiagramEditor diagramEditor = (DiagramEditor)editorPart;
Map epartRegistry =
diagramEditor.getDiagramGraphicalViewer().getEditPartRegistr y();
System.out.println("Number of Elements: " + epartRegistry.size());
for (Iterator iter = epartRegistry.values().iterator();
iter.hasNext();) {
System.out.println("\tEditPart: " + iter.next());
}
System.out.println("======================");
for (Iterator iter = epartRegistry.keySet().iterator();
iter.hasNext();) {
System.out.println("\tView: " + iter.next());
}
System.out.println("======================");
for (Iterator iter = epartRegistry.keySet().iterator();
iter.hasNext();) {
Object view = iter.next();
if(view instanceof View){
System.out.println("\tModel: " + ((View)view).getElement());
}
}
}
