But regardless of the limitation of the core wxWidget componets, we can always go beyond that by using OpenGL. Isn't it right?

Yes, the Motif style open-file-dialog is always hard to swallow on Win or Mac.

But it uses some other extra OpenGL extension for map display. Or it is part of GTK

Yes, and the open-file again is the same. But at least it doesn't use the TK detachable menus that looks like a toilet 
paper. I think that is a mention of that on "The Humane Interface" [Raskin]. It is just insane.
