Re: [gtk-list] pixmaps in gdk window

[Eden Li <tile primenet com>]

gdk_pixmap_create_from_xpm_d() uses the GdkWindow* to get the colormap,
you can pass NULL as the first argument if you supply a proper colormap.
You can use a system default colormap returned by
gdk_colormap_get_system().  The thing about GtkWidgets and their
corresponding GdkWindow is that it doesn't get used until the widget is
realized.  Either you can use the default colormap or realize your widget
with gtk_widget_realize() or you can just pass NULL and use the default
colormap as described above.

Try reading a few docs about GdkPixmap and GdkColormap at
http://gtk.org/rdp/gdk/book1.html, and for a more in depth tutorial about
GDK itself try http://pobox.com/~hp/gnome-app-devel.html (sample chapters
from an upcoming book by Havoc Pennington).

Hope this helps.
