A
radio-button
is a button that can be either selected or deselected, but when selecting it any other buttons in its group will be cleared.
The class
radio-button
inherits most of its behavior from button. Note that it is normally best to use a
radio-button-panel rather than make the individual buttons yourself, as the button-panel provides functionality for handling groups of buttons. However, radio buttons are provided in case you need to have more control over the button's behavior.
(setq button (capi:contain
(make-instance 'capi:radio-button
:text "Press Me")
:process nil))
(setf (capi:button-selected button) t)
(setf (capi:button-selected button) nil)
(setf (capi:button-enabled button) nil)
(setf (capi:button-enabled button) t)
