A check button is a button that can be either selected or deselected, and its selection is independent of the selections of any other buttons.
capi
The class check-button
inherits most of its behavior from the class button. Note that it is normally best to use a check-button-panel rather than make the individual buttons yourself, as the button panel provides functionality for handling groups of buttons. However, check-button
can be used if you need to have more control over the button's behavior.
The following code creates a check button.
(setq button (capi:contain (make-instance 'capi:check-button :text "Press Me")))
The button can be selected and deselected using this code.
(capi:apply-in-pane-process button #'(setf capi:button-selected) t button) (capi:apply-in-pane-process button #'(setf capi:button-selected) nil button)
The following code disables and enables the 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)
