Hi there,
I have a problem with drag and drop in GEF. I am just getting started on GEF
and I managed to create a graphical viewer with some edit parts and figures
inside of it. All I am trying to do now is add a drop listener to the viewer
and print out some message that tells me that a drop has occurred.
Unfortunately I don't even get this to work. After dragging a file (or
anything else) from the Navigator to the editor the UI just hangs and I need
to kill the runtime workbench process in order to continue working. My code
is nothing more than this:
protected void initializeGraphicalViewer() {
GraphicalViewer viewer = getGraphicalViewer();
viewer.setContents(myModel); // PSEUDO
viewer.addDropTargetListener(new MyDropListener(viewer));
}
class MyDropListener extends AbstractTransferDropListener {
public MyDropListener(GraphicalViewer viewer) {
super(viewer);
}
protected void updateTargetRequest() {
System.out.println("Updating request....");
}
}
Am I missing something? Any help much appreciated.....
Dirk
P.S.: the main thread seems to be hanging in a native method call to
COM.DoDragDrop. All other threads are either in sleep() or in wait().

How can I find out which plugins get activated? I tried activating the
GEF.debug methods but it doesn't even get to the point where those debug
infos get printed.
I'll invest this problem a little bit more. I don't think that I can provide
any meaningful input to bugzilla (at this point in time) that would allow
you to recreate this problem.
I'll be back!
