Re: gtk errors "!GTK_WIDGET_REALIZED (widget) failed

[3saul <saul_lethbridge hotmail com>]

I'm doing it to get transparency for the window. The strange thing is is that
the window is in fact shown (realized) using gtk_widget_show before I call
the colormap stuff. I've managed to get this working using straight C but
I'm now creating a gui using libglade. Any idea's what I need to do in
libglade to get this working?
