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