Hi,
I'm trying to select a set of editparts when another editpart is selected
for dragging. When component A is selected for dragging I also want
components B, C, and D to also be selected for the components. I am
essentially trying to do what the marquee tool does but on the fly. I
created a DragTracker and overrid the handleDragStarted() method to select
the other components by using the appendSelection method in
GraphicalViewer. By doing this selection it seems to interupt my drag so
the objects don't actually move. Is there a better place to put this where
it won't override the drag?

You may try with implementing EditPartListener and register it with the
editparts which will then be notified by
EditPartListener#selectedStateChanged(EditPart editpart). @see
GraphicalEditPart#setSelected() for selecting others.

Selecting the other parts using GraphicalEditPart#setSelected() is exactly
what GraphicalViewer#appendSelection() does. It seems that when I add to
my selection group gef trets this as if the drag has finished since each
part that I add gains focus be default. So either I can override the
appendSelection method which I don't want to do or figure out how to
regenerate a drag request. Any ideas on how to do this?
Thanks

Yes, you are right. I tried using EditPartListener & EditPart#setSelected().
All others are selected as well but only the first one moves.
Sorry, I don't have any other idea, but I think overriding appendSelection
should work.

I managed to get it working by updating the operationSet List in
AbsractTool to include all newly selected EditParts. I also had to
setState(STATE_DRAG_IN_PROGRESS). Thanks for your help.

Yandu
