Hi,
I want to drag a tree item to the editor. I want to tracker image showing
the actual size of the object being dropped. Just like when you move a
control, it shows the tracker with the actual size of the object moved.
Could someone tell me how to do it or which classes I should look at?
Thanks,
Kevin

Hi Veronika,
I cannot find the DragDetect function in SWT. Could you tell me which file
I should look at?
Thanks.

control.addListener(SWT.DragDetect, new Listener() {
public void handleEvent(Event e) {
// code to start using Tracker.
}
});
