Hi list, I know when I change the widget's size,it will emit the "configure_event",so the function "gtk_widget_set_size_request()"could work. But I'd like to know is there anything else could do this too? I mean if GTK could send messages to a thread's message queue like in Windows programming? And if so,is there any "message" could let application emit the signal like "configure_event"? Thanks a lot!
