Problem Solved!
Thanks for your efforts, but I think what we all missed was that I had
not registered the pop-up widget with Xmanager. I take it that is
what I'm supposed to do. It seems to do the trick. I didn't forget
to do it, rather I simply didn't know about it, this being my first
popup widget (actually my second - the first had the same problem).
I suppose then that the events were generated, but were never
processed until some action was taken with a registered widget (such
as an expose event).
There is now an extra line in my PropertySheet object method:
> pro myLegend::PropertySheet, group_leader=group_leader, $
> window=window,$
> view=view
> self.window=window
> self.view=view
> wpopup = widget_base( /FLOATING, $
> GROUP_LEADER=GROUP_LEADER $
> )
> button = WIDGET_BUTTON( wpopup, $
> value='Re-draw window', $
> event_pro='handle_all_events', $
> UVALUE = {object:self, $
> method:'ReDraw'} $
> )
> result = WIDGET_PROPERTYSHEET( wpopup, $
> VALUE = self , $
> event_pro = 'handle_all_events', $
> UVALUE = {object:self, $
> method:'ChangeProperty'} $
> )
xmanager, 'PropertySheet', $
wpopup, $
event_handler = 'handle_all_events', $
/NO_BLOCK
> widget_control, wpopup, /realize
> end
Putting this extra line of code in was a wild idea for me which came
from the blue. Please let me know if it's not what I'm supposed to be
doing.
All the best,
Sean
