Drag and Drop between Views [message #52144]

Hello!

There seem to be 2 different kinds of Drag'nDrop in GEF:
1. Inside one viewer- no problems there
2. between different viewers / forms / windows
(Like the templates from the logic example palette)

Both kinds use a DragEditPartsTracker, but in case one, the state changes to
4 on movement
while in case 2 is the state will be 2 till the drop.
Only case 2 will print Drag Events in the debug window.

What is the difference and how can I tell my EditParts to use the second
kind?

Thanks for any help,
Manfred Goetz.

When using native drag and drop, the DragEditPartsTracker is not used to
perform the drag. Its function is simply to select the EditPart on mouse
down. It gets unloaded immediately if a native drag begins.
