| Adds a drag listener to the given control. The behavior is very similar
to control.addListener(SWT.DragDetect, dragListener), however the listener
attached by this method is less sensitive. The drag event is only fired
once the user moves the cursor more than HYSTERESIS pixels.
This is useful for registering a listener that will trigger an editor or
view drag, since an overly sensitive drag listener can cause users to accidentally
drag views when trying to select a tab.
Currently, only one such drag listener can be registered at a time.
Parameters:
control - the control containing the drag listener
Parameters:
externalDragListener - the drag listener to attach |
