GdkPixmap *
gdk_bitmap_create_from_data (GdkWindow *window,
			     gchar     *data,
			     gint       width,
			     gint       height)
GtkWidget*
gtk_pixmap_new (GdkPixmap *normal,
		GdkPixmap *active,
		GdkPixmap *prelight,
		GdkPixmap *selected,
		GdkPixmap *insensitive)

gdk_bitmap_create_from_data returns a GdkPixmap type and gtk_pixmap_new
wants such a type. I can not see any type conflict.
