Setting background pixmap for a GtkLabel

[Kevin Vandersloot <kfv101 psu edu>]

Hi All. I'm trying to fix up applet transparency, and I can't seem to be
able to set the background pixmap of an applet. I've tried
gdk_window_set_back_pixmap for the PanelApplet widget as well as for the
GtkLabel widget that I'm testing, but neither seem to work.

So my question is what is the standard way to set a bakcground pixmap
for a GtkLabel, or other GtkWidgets? I appreciate any help.

Regards,
Kevin
