Variable: MenuButton
constMenuButton:object
Defined in: react/src/generated/jsx.ts:13867
Displays a popup when clicked.
This popup can be provided either as a GtkPopover or as an abstract
GMenuModel.
The GtkMenuButton widget can show either an icon (set with the
[property@Gtk.MenuButton:icon-name] property) or a label (set with the
[property@Gtk.MenuButton:label] property). If neither is explicitly set,
a [class@Gtk.Image] is automatically created, using an arrow image oriented
according to [property@Gtk.MenuButton:direction] or the generic
“open-menu-symbolic” icon if the direction is not set.
The positioning of the popup is determined by the [property@Gtk.MenuButton:direction] property of the menu button.
For menus, the [property@Gtk.Widget:halign] and [property@Gtk.Widget:valign] properties of the menu are also taken into account. For example, when the direction is %GTK_ARROW_DOWN and the horizontal alignment is %GTK_ALIGN_START, the menu will be positioned below the button, with the starting edge (depending on the text direction) of the menu aligned with the starting edge of the button. If there is not enough space below the button, the menu is popped up above the button instead. If the alignment would move part of the menu offscreen, it is “pushed in”.

CSS nodes
menubutton
╰── button.toggle
╰── <content>
╰── [arrow]
GtkMenuButton has a single CSS node with name menubutton
which contains a button node with a .toggle style class.
If the button contains an icon, it will have the .image-button style class,
if it contains text, it will have .text-button style class. If an arrow is
visible in addition to an icon, text or a custom child, it will also have
.arrow-button style class.
Inside the toggle button content, there is an arrow node for
the indicator, which will carry one of the .none, .up, .down,
.left or .right style classes to indicate the direction that
the menu will appear in. The CSS is expected to provide a suitable
image for each of these cases using the -gtk-icon-source property.
Optionally, the menubutton node can carry the .circular style class
to request a round appearance.
Accessibility
GtkMenuButton uses the [enum@Gtk.AccessibleRole.button] role.
