[Gtk-sharp-list] method CreateFromXpmD parameters

[Joeri Belis]

trying to use the CreateFromXpmD static method, i get the following error.

Main.cs(144) error CS1502: The best overloaded match for method
'Gdk.Pixmap.CreateFromXpmD(Gdk.Drawable, Gdk.Bitmap, Gdk.Color, string)' has
some invalid arguments
Main.cs(144) error CS1503: Argument 2: Cannot convert from 'Gdk.Pixmap' to
'Gdk.Bitmap'
Main.cs(144) error CS1501: No overload for method `CreateFromXpmD' takes `4'
arguments

But looking at the documentation is see

CreateFromXpmD(Drawable, out Pixmap, Color, string[]) : Pixmap

Why is there GDK.Bitmap when the docs sais Pixmap

I can't even find GDK.Bitmap at
http://go-mono.com/docs/index.aspx?link=root:/classlib-gnome.
