I don't creat it. I use my widget like GtkWidget.

I creat my widget with GdkWindow becouse it's needed by xine, but
widget->window is NULL.

I just don't know how to revice events fro my widget in my program
without using extra thread (gxine and totem uses Xlib and new thread to
revice events, I want to use GDK and no new thread becouse I thing gtk
should pass events to my widget).
