no, it means that the widget has been realized .... that is, a low level

So, be drawed  is the "been realized", right?

you cannot predict or even directly control when this happens, so i
wouldn't bother to try. if you want the geometry, the best thing to do
is to catch configure-events on the parent top level window
(configure-event is only sent to top level windows), and then query the
widget. you can be certain that (a) it will have a window at that time
and (b) the window manager (or its equivalent on different platforms)
has finished (for now) with controlling the top level window dimensions.

 

So far, the segmentation fault problem was solved.
And I found a method, is_realized(), and I will do more test.
Thanks Paul!
