| Allegro CL version 6.2 Unrevised from 6.1 | |||||||||
A non-instantiable class that provides specific behavior for using the
keyboard to move the keyboard focus among the controls on a window by
pressing the TAB key (or arrow keys in a group of buttons) or the
various ALT key shortcuts for each widget. This mixin also provides
the behavior where pressing the Enter key emulates pushing the default-button that's on
the window (if any), and pressing the Escape key emulates pressing the
cancel-button
(if any).
Usually this behavior is obtained by instantiating the built-in
dialog class to
create a window that is to have controls on it, but this mixin class
exists separately in case this special dialog behavior needs to be
mixed with other window classes.
