A class of window that by default has a border, scrollbars, and a
title-bar with the standard small buttons for iconizing, maximizing,
and closing the window. Otherwise a frame-window
is a general window
similar to a basic-pane. Despite the name, which might suggest that
the window is useful only for adding a frame around other windows, a
frame-window
can
be drawn on directly.
This class is suitable to use as the superclass of custom application
window classes that have borders and titlebars. frame-window
s are also resizable by
default, though this can be overridden, for example, by explicitly
passing the resizable keyword argument to make-window as nil
, or by specifying the :resizable
:default-initarg
of a subclass as nil
. Any other window attributes that a particular
window class provides by default may be turned off similarly, or
additional attributes added.
For windows that are also to have a toolbar or status-bar, the non-refreshing-window
class is recommended instead due to its frame-with-single-child
properties
that accomodate toolbars and status-bars. If backing-store is desired,
instead use a bitmap-pane
or bitmap-window
. When adding
controls, a dialog
is recommended.
