Hi,
I want to create a new Figure in my Diagram where the Drop occurs. In order
to do that I change the NativeDropRequest to save the (x,y) of the drop
event and in my TextTransferDropTargetListener, I call the getCurrentEvent()
and get the (x,y) of that event.
But what I find out is the (x,y) co-ordinate of the getCurrentEvent() is
different from what i expected. I drop the text in the top left side of my
diagram, the (x,y) co-ordinate of the getCurrentEvent() is (357, 369). I
expect x, y-coordinate should be in the range of 100. So even I drop in in
the top lef side of my diagram, the figure is created in the bottom right
side of my diagram.
Could someone please tell me if my approach is correct? If not, please tell
me what did I miss.
Thank you.
Changes I made in the TextTransferDropTargetListener:
protected Request createTargetRequest() {
DropTargetEvent event = getCurrentEvent();
NativeDropRequest dropRequesgetCurrentEventt = new NativeDropRequest();
System.out.println("x" + event.x + "y"+event.y);
dropRequest.setX(event.x);
dropRequest.setY(event.y);
return dropRequest;
}
protected void updateTargetRequest(){
DropTargetEvent event = getCurrentEvent();
System.out.println("x" + event.x + "y"+event.y);
getNativeDropRequest().setX(event.x);
getNativeDropRequest().setY(event.y);
getNativeDropRequest().setData(getCurrentEvent().data);
}

No time to check this now, but try
AbstractTransferDropTargetListener.getDropLocation()

Yes, I think that one is EditPartViewer-relative.
SWT sends a Display-relative coordinate.
