Sael aftur !
Thanks for all your suggestions and ideas
After further investigation and tests it turns out that the costing event is the
connection to expose_event of the DrawingArea, not the mouse_motion, nor the resizing
of the window.
self.area.connect("expose-event", self.area_expose_cb)
this redraws the content of the window.
The high CPU usage happens even when the whole window containing the drawingArea is
minimized. Is this normal ?
What could I do to avoid such problem of updates?
Takk
