Hi,

Is there a way to get information about the keystat while a drop occurs?
I'd like to know wether Shift or Control is pressed, simultaneously.

Regards,

Niels

Hi.

The value of "detail" is decided by the modifiers pressed:

DND.DROP_MOVE => no modifier or Shift or Alt + any other modifier
DND.DROP_COPY => Control
DND.DROP_LINK => Alt or Shift + Control

But only if the dragSource and dropTarget both support the operation,
otherwise its DND.DROP_NONE.

Greetings,
Tim

Hmm, somehow it is not working for me. I can see Alt or Control, but never
Shift.

One more question: I'm using a LocalSelectionTransfer to see what kind of
selection is going to be dropped. If the dropTarget component doesn't like
the selection is it possible to programmatically stop the drag event?

Thanks, Niels

Ok, I can answer the last question by myself: using event.detail =
DND.DROP_NONE.

But Shift is not working for me...

Well, Shift is the same as no modifier pressed (DND.DROP_MOVE), so there
is no change. So, no, Shift can not be detected.

Setting operation to DND.DROP_NONE during dropAccept prevents the drop
event. Does that help?
