Hi All,
In our Eclipse/GEF application we need to implement dragging from a
table into a GEF graphical viewer. This works well on Windows and Linux,
but not on OSX.
On the Table Viewer we initilize the drag source listener with
DragSourceListener dragSourceListener = new DragSourceListener(){
public void dragStart(DragSourceEvent event) {
IStructuredSelection selection =
(IStructuredSelection) tableViewer.getSelection();
if (selection.size() == 0) {
event.doit = false;
}
LocalSelectionTransfer.getInstance().setSelection(selection) ;
}
public void dragSetData(DragSourceEvent event) {
dragStart(event);
}
public void dragFinished(DragSourceEvent event) {
tableViewer.refresh();
}
};
int operations = DND.DROP_COPY;
Transfer[] types = new Transfer[]
{LocalSelectionTransfer.getInstance()};
tableViewer.addDragSupport(operations, types, dragSourceListener);
On the GEF viewer we have :
ScrollingGraphicalViewer viewer =
ScrollingGraphicalViewer)getGraphicalViewer();
viewer.addDropTargetListener(new MyDropTargetListener(viewer));
public class MyDropTargetListener extends
AbstractTransferDropTargetListener {
// various methods
}
The drag does get initiated but none of the methods in
MyDropTargetListener get called.
We do set data inside dragSetData as per the post:

Any help is greatly appreciated
thanks
