gtk:frame-label (object)

object -- a gtk:frame widget
label -- a string for the text to use as the label of the frame

The accessor for the label slot of the gtk:frame class gets or sets the text in the label. Returns nil if there was no label widget or the label widget was not a gtk:label widget. If the label argument is nil, the current label is removed.

The frame will have a gtk:label widget for the label widget if a non-nil argument was passed to the gtk:frame-new function.
