Description

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.

Example

(setq button (capi:contain

              (make-instance 'capi:radio-button

                             :text "Press Me")))

(capi:apply-in-pane-process

 button #'(setf capi:button-selected) t button)

(capi:apply-in-pane-process 

 button #'(setf capi:button-selected) nil button)

(capi:apply-in-pane-process 

 button #'(setf capi:button-enabled) nil button)

(capi:apply-in-pane-process 

 button #'(setf capi:button-enabled) t button)

There is a further example in the file examples/capi/buttons/buttons.lisp .
