gtk:expander-label (object)

object -- a gtk:expander widget
label -- a string with the text of the label of the expander

Accessor of the label slot of the gtk:expander class. The gtk:expander-label function fetches the text from a label widget including any embedded underlines indicating mnemonics and Pango markup, as set by the (setf gtk:expander-label) function.

If the label text has not been set the return value will be nil. This will be the case if you create an empty button with the gtk:button-new function to use as a container.
