enhancements to wxStackFrame for Linux

[Francesco Montorsi]

Hi all,

> IMHO the best thing to do would be to use a (generic) wxAssertDialog 
Unfortunately using a generic dialog from an assert I'm seeing some very 
strange effects (under wxGTK): the dialog is partly not redrawn, it gets 
automatically a resize border even if I explicitely used 
~wxRESIZE_BORDER, wxCollapsiblePane does not get right size when 
expanded, when the user resizes it the controls are not resized, etc etc.

If I create the dialog in a "safe" execution point of a wx sample 
however it does show and works right.

So, as Vadim said, maybe using a wx-thing as assert box may not be a 
reliable idea.

Nonetheless I really hate having stack frame lines all wrapped under 
wxGTK so I'd solve the problem making the generic assert dialog which I 
already have created as a C-only plain GTK widget and use it only under 
wxGTK.

That hopefully would remove all sorts of problems...

BTW: does anyone knows why from using a wxDialog from 
wxGUIAppTraitsBase::ShowAssertDialog() provokes those weird effects?

Thanks,
Francesco
