Hi lian,

for actual drag'n'drop, you need an IOnDragDropHandler.

The IOnDragHandler is used for simple mouse events, reacting to a mouse with pressed button being dragged over the scene. It does not know about any "context" other than the visual/part that is dragged (i.e. pressed).

The IOnDragDropHandler is used for full drag'n'drop, i.e. external files being dropped onto the application, etc.

Best regards,
Matthias
