A widget that shows a menu when clicked on.
This menu can be provided either as a Gtk::Menu, a Gtk::Popover or an abstract Gio::MenuModel.
The Gtk::MenuButton widget can show either an icon (set with set_icon_name()) or a label (set with set_label()). If neither is explicitly set, a Gtk::Image is automatically created, using an arrow image oriented according to set_direction() or the generic “open-menu-symbolic” icon if the direction is not set.
using Gtk::MenuButton::SlotCreatePopup = sigc::slot<void()> |
Slot to create a popup for the MenuButton on demand.
This slot is called when the popoup of the MenuButton is shown, but none has been provided via set_popup(), set_popover() or set_menu_model().
