Re: [gtk-list] Re: rewrite question:how to attach a pixmap to a GtkWindow as the background

[Jiang XU <jiang xu echostar com>]

I have been driven crazy!!

But, first thanks Todd!, at least I can get the GdkWindow.
But I still can not put the pixmap as the background of the GtkWIndow. It
doesn't show up!!
So, I guess I still need Help!!
Thanks very much!!

The following is the source code (test example), it only include one table and
one button:
I use gtk_window_new to create window1 and use gtk_widget_realize to set
window1->window, then I use gdk_window_set_back_pixmap to set the pixmap as
the background. but when run the application, it does not show the pixmap.  I
wonder what's wrong!

Need help!!
Thanks very very much!
