## 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.

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