Hi,

How could add Drag&Drop support for a custom control ?
I have a custom table control, on dragOver event I specify
DND.FEEDBACK_SCROLL | DND.FEEDBACK_SELECT but nothing happens. For
DND.FEEDBACK_SCROLL in the javadoc says that "The widget is scrolled up or
down to allow the user to drop on items that are not currently visible".
What do I need to implement in my custom control ?

Another question: why is not applicable DND.FEEDBACK_SCROLL for a list
control too ?

Best regards,
Boby

Currently there is no story for how widgets can add response to drag under
effects in DND. It is one of the things I am hoping to address in 3.1.
All widgets, including List, will be reviewed and given appropriate drag
under effect behaviour at that time.
