Hi,

I don't know if you already have some answers... I just found now your
mail again... And try to give you some little info.

* Did you read the wiki on picogui.org? The page about context?
  http://www.picogui.org/wiki/view/Main/ContextMemoryManagement

* PicoGUI act as GTK. It use one eventloop that process the events
  produced mainly by the client

* When you are not in the eventloop (after a pgExitEventLoop for exemple)
  the server won't do updates and then you must do them by yourselef

* Maybe redesign your app to stay in the eventloop

Hope this help,
-philippe

[Pgui-devel] Re:Screen not redrawing automatically

[sanit]

hi Philippe,
   I did find some time the screen could not redraw. It seem some bugs of certain 
widget, such as cavans and textbox widget.
   Not redaw occurs in the flowing station:
   a program (that had a canvas or textbox widget) run first, this program had a 
button, that will call a dialog or a menu(it will not full screen), when you exit from 
the dialog or menu, the canvas or textbox will not redraw. 
   it seem in those widget we should call " div_rebuild(self->in->div) "in somewhere, 
I tried, but not correct all.
