Hi,

I noticed that DropTargetEvent.x and y are calculated relative to the
Display.
I need to calculate them relative to my DropTarget (in this case Canvas). Is
there some convenience method that I could use to do this?

Hi Sami,
try the toControl(Point p), toControl(int x, int y) ... this translates
global (Display) coordinates to local (Canvas or any other control) ones.

Ciao,
