gtk-toolbar-show-arrow (object)

toolbar -- a gtk-toolbar widget
setting -- a boolean whether to show an overflow menu

Accessor of the show-arrow slot of the gtk-toolbar class.

The gtk-toolbar-show-arrow slot access function returns whether the toolbar has an overflow menu. The (setf gtk-toolbar-show-arrow) slot access function sets whether to show an overflow menu when the toolbar is not allocated enough size to show all of its items. If true, items which cannot fit in the toolbar, and which have a proxy menu item set by the gtk-tool-item-proxy-menu-item function or a "create-menu-proxy" signal handler, will be available in an overflow menu, which can be opened by an added arrow button. If false, the toolbar will request enough size to fit all of its child items without any overflow.
