<title>MenuButton</title>
<media type="image" mime="image/png" src="media/menubutton.png"/>
<p>The GtkMenuButton widget is used to display a menu when clicked on. This menu can be provided either as a GtkMenu, or an abstract GMenuModel. The GtkMenuButton widget can hold any valid child widget. That is, it can hold almost any other standard GtkWidget. The most commonly used child is the provided GtkArrow.</p>
<note><p>Du behöver köra GNOME 3.6 eller senare för att MenuButton ska fungera.</p></note>
