Greetings,
gtk_widget_show() does not seem to be operating the way I expect;
could one of the experts please tell me if something is wrong with
this code or if something is wrong with gtk?
When I run this small bit of code, the window appears briefly
and then disappears immediately. The program does not exit.
I expect the window to stay visible (due to gtk_widget_show()),
but it's not happening.
many thanks!
