I originally posted this to the glade-users list, but I think it belongs in the gtkglext list instead.
I have a window with two GtkDrawingArea's. One is a map and one is a
picture, I'm trying to swap the two windows with the click of a
button. Surrounding each drawing is a bunch of buttons and things.
This is how I reparent them:
The buttons, the boxes, and everything in the widgets swaps out,
but the next time I try to draw in either of them, the
GdkGKExt-CRITICAL **: gdk_gl_window_impl_x11_make_context_current: assertion 'GDK_IS_GL_CONTEXT_IMPL_X11 (glcontext)' failed
So, that's a bummer. I didn't write the code I'm using to
instantiate the widgets, or draw the pic/map. I'm wondering if maybe
the problem is that the "realize" event gets called twice, but all the
gdk setup stuff is actually in a different method, one that doesn't get
called twice. The realize callback doesn't really have anything in it.
Any help would be appreciated. I'm running in circles.
