Implemented Interfaces

GtkToolbar implements AtkImplementorIface, GtkBuildable, GtkToolShell and GtkOrientable.

Includes

#include <gtk/gtk.h>

Description

A toolbar is created with a call to gtk_toolbar_new().

A toolbar can contain instances of a subclass of GtkToolItem. To add a GtkToolItem to the a toolbar, use gtk_toolbar_insert(). To remove an item from the toolbar use gtk_container_remove(). To add a button to the toolbar, add an instance of GtkToolButton.

Toolbar items can be visually grouped by adding instances of GtkSeparatorToolItem to the toolbar. If the GtkToolbar child property “expand” is TRUE and the property “draw” is set to FALSE, the effect is to force all following items to the end of the toolbar.

By default, a toolbar can be shrunk, upon which it will add an arrow button to show an overflow menu offering access to any GtkToolItem child that has a proxy menu item. To disable this and request enough size for all children, call gtk_toolbar_set_show_arrow() to set “show-arrow” to FALSE.

Creating a context menu for the toolbar can be done by connecting to the “popup-context-menu” signal.

GtkToolbar has a single CSS node with name toolbar.
