Hi, I've just started using GTK and GtkGLArea imparticular, and I've got a problem with signals...
I have a callback that is responsible for redrawing the glarea widget when it receives an "expose_event" signal, which works fine when just resizing the window etc. But I also want a mouse motion callback to trigger a redraw of the widget, in much the same as you can use glutPostRedisplay() with GLUT. So I tried using gtk_signal_emit_by_name(GTK_OBJECT(gd.gl3dview), "expose_event", NULL) but this gives a segfault. When I looked at the example code for the lightwave object viewer it uses gtk_widget_draw() to accomplish the redraw. Why is it that I can't simply have the glarea widget signal itself that it is in need of a refresh? Isn't a widget allowed to signal itself?
