## 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 a GtkSeparatorToolItem has the "expand" property set to TRUE and the "draw" property 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.

## Details

### GtkToolbar

    typedef struct {
      gint             GSEAL (num_children);
      GList           *GSEAL (children);
      GtkOrientation   GSEAL (orientation);
      GtkToolbarStyle  GSEAL (style);
      GtkIconSize      GSEAL (icon_size);

    #ifndef GTK_DISABLE_DEPRECATED
      GtkTooltips     *GSEAL (tooltips);
    #else
      gpointer         GSEAL (_tooltips);
    #endif
    } GtkToolbar;

The GtkToolbar struct only contains private data and should only be accessed through the function described below.

### enum GtkToolbarChildType

    typedef enum
    {
      GTK_TOOLBAR_CHILD_SPACE,
      GTK_TOOLBAR_CHILD_BUTTON,
      GTK_TOOLBAR_CHILD_TOGGLEBUTTON,
      GTK_TOOLBAR_CHILD_RADIOBUTTON,
      GTK_TOOLBAR_CHILD_WIDGET
    } GtkToolbarChildType;

### Warning

`GtkToolbarChildType` is deprecated and should not be used in newly-written code.

GtkToolbarChildType is used to set the type of new elements that are added to a GtkToolbar.

### Warning

`gtk_toolbar_insert_element` is deprecated and should not be used in newly-written code.

Inserts a new element in the toolbar at the given position.

If `type` == `GTK_TOOLBAR_CHILD_WIDGET`, `widget` is used as the new element. If `type` == `GTK_TOOLBAR_CHILD_RADIOBUTTON`, `widget` is used to determine the radio group for the new element. In all other cases, `widget` must be `NULL`.

`callback` must be a pointer to a function taking a GtkWidget and a gpointer as arguments. Use the `GTK_SIGNAL_FUNC()` to cast the function to GtkSignalFunc.

`toolbar` : | a GtkToolbar.
`type` : | a value of type GtkToolbarChildType that determines what `widget` will be.
`widget` : | a GtkWidget, or `NULL`.
`text` : | the element's label.
