Hi Andi,

If you enable tracking events for your draw widget, you can change the
cursor when the pointer enters or leaves the widget. This will let
you set the cursor for an individual widget rather than the whole
hierarchy. For example, in your event handler, deal with tracking
events something like this:

case tag_names(event, /structure_name) of
'WIDGET_TRACKING': begin
if event.enter then begin
;; switch to the cursor for this widget:
device, cursor_standard=40
endif else begin
;; switch to my default cursor:
device, /cursor_crosshair
endelse
end
'WIDGET_DRAW': begin
;; deal with draw events...
end
else: ;; deal with other event types...
endcase
