 373  * @base_width: allowed window widths are @base_width + @width_inc * N where N
 374  *  is any integer (-1 allowed with #GtkWindow)
 375  * @base_height: allowed window widths are @base_height + @height_inc * N where
 376  *  N is any integer (-1 allowed with #GtkWindow)
 377  * @width_inc: width resize increment
 378  * @height_inc: height resize increment
 379  * @min_aspect: minimum width/height ratio

 381  * @win_gravity: window gravity, see gtk_window_set_gravity()
 382  *
 383  * The #GdkGeometry struct gives the window manager information about
 384  * a window's geometry constraints. Normally you would set these on
 385  * the GTK+ level using gtk_window_set_geometry_hints(). #GtkWindow
 386  * then sets the hints on the #GdkWindow it creates.
 387  *
 388  * gdk_window_set_geometry_hints() expects the hints to be fully valid already
 389  * and simply passes them to the window manager; in contrast,
 390  * gtk_window_set_geometry_hints() performs some interpretation. For example,
 391  * #GtkWindow will apply the hints to the geometry widget instead of the
 392  * toplevel window, if you set a geometry widget. Also, the
 393  * @min_width/@min_height/@max_width/@max_height fields may be set to -1, and
 394  * #GtkWindow will substitute the size request of the window or geometry widget.
 395  * If the minimum size hint is not provided, #GtkWindow will use its requisition
 396  * as the minimum size. If the minimum size is provided and a geometry widget is
 397  * set, #GtkWindow will take the minimum size as the minimum size of the
 398  * geometry widget rather than the entire window. The base size is treated
 399  * similarly.
 400  *
 401  * The canonical use-case for gtk_window_set_geometry_hints() is to get a
 402  * terminal widget to resize properly. Here, the terminal text area should be
 403  * the geometry widget; #GtkWindow will then automatically set the base size to
 404  * the size of other widgets in the terminal window, such as the menubar and
 405  * scrollbar. Then, the @width_inc and @height_inc fields should be set to the
 406  * size of one character in the terminal. Finally, the base size should be set
 407  * to the size of one character. The net effect is that the minimum size of the
 408  * terminal will have a 1x1 character terminal area, and only terminal sizes on
 409  * the "character grid" will be allowed.
 410  *
 411  * Here's an example of how the terminal example would be implemented, assuming
 412  * a terminal area widget called "terminal" and a toplevel window "toplevel":

 414  * <informalexample><programlisting><![CDATA[
