- * gdk_surface_set_decorations:
- * @surface: a toplevel #GdkSurface
- * @decorations: decoration hint mask
- *
- * “Decorations” are the features the window manager adds to a toplevel #GdkSurface.
- * This function sets the traditional Motif window manager hints that tell the
- * window manager which decorations you would like your surface to have.
- * Usually you should use gtk_window_set_decorated() on a #GtkWindow instead of
- * using the GDK function directly.
- *
- * The @decorations argument is the logical OR of the fields in
- * the #GdkWMDecoration enumeration. If #GDK_DECOR_ALL is included in the
- * mask, the other bits indicate which decorations should be turned off.
- * If #GDK_DECOR_ALL is not included, then the other bits indicate
- * which decorations should be turned on.
- *
- * Most window managers honor a decorations hint of 0 to disable all decorations,
- * but very few honor all possible combinations of bits.
