Subject	Re: [platform-swt-dev] GC for a Canvas, how to draw OVER children controls

Hi,
 
sorry if this registers as another thread,
something went wrong with my subscription to this email list, althought
I assume that the subject testing will still recognise it and place it
in the right thread.
 
Anyway,
 
I understand the the GC drawing will be clipped
to mainCanvas, what I meant was is there a way to tell the GC the lines
over the controls that are children of mainCanvas. Currently it draws the
lines 'behind' the controls.
 
so is there a zIndex setting or something
similar.
 
Regards
 
Steve

Not currently.  All drawing is clipped
to the control.

Hi there,
  
I have succesfully implemented some code where, if I drag and drop from
a label in one canvas (cnv) to one in another (cnv2), the parent canvas'
(mainCanvas) PaintListener will draw a line from one label to the other.
  
so cnv1 and cnv2 are descendants of mainCanvas. 
  
The problem I have, is that mainCanvas' GC draws the line behind the controls.
  
Is there a way to get the GC to draw the line over the child controls??
  
Any help would be appreciated
  
Regards 
  
Steve
