Drag And Drop Best practice ? [message #452090]

Hi,

I use a Tree viewer as a Drag source and a Composite as a Drop target.
Users can so drag and drop tree nodes content.

I'm now asked to modify this by creating a new Composite (in a new Shell)
if the user drops the tree node outside the existing drop target.

So I have now one drag source and two distinct drop targets.

To determine whether the drop has been done on the dedicated Composite or
outside, I read the event.detail content in the dragFinished method, if it
is equal to DND.DROP_NONE, the drop has been done outside the Composite.

Is it a good way to do this ???

Thanks
Helene
