gtk:check-button-label (object)

object -- a gtk:check-button widget
label -- a string with the text of the label widget inside the button

Accessor of the label slot of the gtk:check-button class. The gtk:check-button-label function returns the label of the check button or nil if the child property is set. The (setf gtk:check-button-label) function sets the text. If the use-underline property is true, an underscore in label is interpreted as mnemonic indicator, see the gtk:check-button-use-underline function for details on this behavior.
