 371  * @width_inc: width resize increment
 372  * @height_inc: height resize increment
 373  * @min_aspect: minimum width/height ratio
 374  * @max_aspect: maximum width/height ratio
 375  * @win_gravity: window gravity, see gtk_window_set_gravity()
 376  *
 377  * The #GdkGeometry struct gives the window manager information about
 378  * a window's geometry constraints. Normally you would set these on
 379  * the GTK+ level using gtk_window_set_geometry_hints(). #GtkWindow
 380  * then sets the hints on the #GdkWindow it creates.
 381  *
 382  * gdk_window_set_geometry_hints() expects the hints to be fully valid already
 383  * and simply passes them to the window manager; in contrast,
 384  * gtk_window_set_geometry_hints() performs some interpretation. For example,
 385  * #GtkWindow will apply the hints to the geometry widget instead of the
 386  * toplevel window, if you set a geometry widget. Also, the
 387  * @min_width/@min_height/@max_width/@max_height fields may be set to -1, and
 388  * #GtkWindow will substitute the size request of the window or geometry widget.
 389  * If the minimum size hint is not provided, #GtkWindow will use its requisition
 390  * as the minimum size. If the minimum size is provided and a geometry widget is
 391  * set, #GtkWindow will take the minimum size as the minimum size of the
 392  * geometry widget rather than the entire window. The base size is treated
 393  * similarly.
 394  *
 395  * The canonical use-case for gtk_window_set_geometry_hints() is to get a
 396  * terminal widget to resize properly. Here, the terminal text area should be
 397  * the geometry widget; #GtkWindow will then automatically set the base size to
 398  * the size of other widgets in the terminal window, such as the menubar and
 399  * scrollbar. Then, the @width_inc and @height_inc fields should be set to the
 400  * size of one character in the terminal. Finally, the base size should be set
 401  * to the size of one character. The net effect is that the minimum size of the
 402  * terminal will have a 1x1 character terminal area, and only terminal sizes on
 403  * the "character grid" will be allowed.
 404  *
 405  * Here's an example of how the terminal example would be implemented, assuming
 406  * a terminal area widget called "terminal" and a toplevel window "toplevel":
 407  *
 408  * <informalexample><programlisting><![CDATA[

 428  * is set, the aspect applies to the geometry widget rather than the entire
 429  * window. The most common use of these hints is probably to set @min_aspect and
 430  * @max_aspect to the same value, thus forcing the window to keep a constant
