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: gtk_widget_ref(map_widget); gtk_widget_ref(pic_widget); gtk_container_remove(left_container, map_widget); gtk_container_remove(right_container, pic_widget); gtk_container_add(left_container, pic_widget); gtk_container_add(right_container, map_widget); gtk_widget_unref(map_widget); gtk_widget_unref(pic_widget); The buttons, the boxes, and everything in the widgets swaps out, but the next time I try to draw in either of them, the gdk_gl_drawable_gl_begin fails: 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. Jeff
