public void set_show_arrow (bool show_arrow)
Sets whether to show an overflow menu when this isn’t allocated enough size to show all of its items.
If true, items which can’t fit in this, and which have a proxy menu item set by set_proxy_menu_item or create_menu_proxy, will be available in an overflow menu, which can be opened by an added arrow button. If false, this will request enough size to fit all of its child items without any overflow.
