Hi,
I am trying to get drag and drop working on a TableTreeViewer control
and am having a problem. Using the following code:
// add drag support to viewer
Transfer[] transfer = new Transfer[] { TextTransfer.getInstance()};
viewer.addDragSupport(DND.DROP_COPY | DND.DROP_MOVE, transfer,
new MyDragListener(viewer));
I stepped through the code in the debugger, and the addDragSupport
method seems to work fine, the listener is added correctly. However no
dragging event occurs when I attempt to drag an item in the viewer.
As a test, I dropped the exact same code in to a TableViewer control I
am using (only changing the viewer param). In that case it worked - the
drag event was being generated.
Is there something special about a TableTreeViewer when it comes to
generating a drag event?
Thx,
evan
