Description Francis Upton IV CLA 2005-10-04 17:32:55 EDT 
In my application, when the user initiates a drag from a Tree (I'm using a JFace
TreeViewer), I would like this to not select the TreeItem.

I prefer not to try to deal with the low-level mouse events for detecting the
drag, since this deals with platform-specific mechanisms.

However, when I tried listening to the SWT.Selection, SWT.DragDetect, and the
TreeViewer selection and DragStart events, the selection events always appear
first, so I'm not able to determine that the selection was caused by the start
of a drag (so I can ignore/reverse the selection).
