gtk:menu-button-can-shrink (object)

object -- a gtk:menu-button widget
setting -- a boolean whether the menu button can shrink

The accessor for the can-shrink slot gets or sets whether the menu button can be smaller than the natural size of its contents.

For text menu buttons, setting the can-shrink property to true will ellipsize the label. For icon menu buttons, this function has no effect.
