wxGTK-3.0.0: Many ASSERTS with wxAuiNotebook in auidemo

[Marco DeFreitas]

I've been seeing asserts in my application that uses wxAuiNotebook, which
can be duplicated in the auidemo sample program.

If I create a new notebook panel by:
View->Create Notebook

I get the following asset:

Gdk-CRITICAL **: gdk_window_thaw_updates: assertion
`impl_window->update_freeze_count > 0' failed

I also noticed that the "View" menu label on the menubar stays
"highlighted", and I cannot "unhighlight" it.

Also, if I dock this newly created panel, I get:

(auidemo:25393): Gdk-CRITICAL **: _gdk_pixmap_new: assertion `(width != 0)
&& (height != 0)' failed
(auidemo:25393): Gdk-CRITICAL **: gdk_draw_rectangle: assertion

Does anybody else see this?

Thanks!

I can't reproduce neither of these two problems here with the latest
trunk.

I do see those. It looks like a bug in wxAuiTabContainer::Render() which
creates the off screen bitmap even when its width is 0. But maybe its size
shouldn't be 0 in the first place. I really don't know how is this code
supposed to work. And I think it's quite likely that this has been already
changed in the dynamic-notebook wxAUI branch... So I'm not going to debug
this, but perhaps it would be worth creating a ticket for this and retest
and possibly close it when the dynamic-notebook branch is merged.

Is it going to be merged in 3.0.1?

Thanks,

No, definitely not. Hopefully in 3.2.0.
