- * @geometry: geometry string

- * Parses a standard X Window System geometry string - see the
- * manual page for X (type “man X”) for details on this.
- * gtk_window_parse_geometry() does work on all GTK+ ports
- * including Win32 but is primarily intended for an X environment.
- *
- * If either a size or a position can be extracted from the
- * geometry string, gtk_window_parse_geometry() returns %TRUE
- * and calls gtk_window_set_default_size() and/or gtk_window_move()
- * to resize/move the window.
- *
- * If gtk_window_parse_geometry() returns %TRUE, it will also
- * set the #GDK_HINT_USER_POS and/or #GDK_HINT_USER_SIZE hints
- * indicating to the window manager that the size/position of
- * the window was user-specified. This causes most window
- * managers to honor the geometry.
- *
- * Note that for gtk_window_parse_geometry() to work as expected, it has
- * to be called when the window has its “final” size, i.e. after calling
- * gtk_widget_show_all() on the contents and gtk_window_set_geometry_hints()
