## Implemented Interfaces

GtkToolItem implements AtkImplementorIface, GtkBuildable and GtkActivatable.

## Includes

    #include <gtk/gtk.h>

## Description

GtkToolItems are widgets that can appear on a toolbar. To create a toolbar item that contain something else than a button, use `gtk_tool_item_new()`. Use `gtk_container_add()` to add a child widget to the tool item.

For toolbar items that contain buttons, see the GtkToolButton, GtkToggleToolButton and GtkRadioToolButton classes.

See the GtkToolbar class for a description of the toolbar widget, and GtkToolShell for a description of the tool shell interface.

    void
    gtk_tool_item_set_proxy_menu_item (GtkToolItem *tool_item,
                                       const gchar *menu_item_id,
                                       GtkWidget *menu_item);

Sets the GtkMenuItem used in the toolbar overflow menu. The `menu_item_id` is used to identify the caller of this function and should also be used with `gtk_tool_item_get_proxy_menu_item()`.

See also “create-menu-proxy”.

The function must be called when the tool item changes what it will do in response to the “create-menu-proxy” signal.

#### Parameters

tool_item | a GtkToolItem |

Since: 2.6

### gtk_tool_item_toolbar_reconfigured ()

    void
    gtk_tool_item_toolbar_reconfigured (GtkToolItem *tool_item);

Since: 2.20

## Types and Values

### struct GtkToolItem

    struct GtkToolItem;

The GtkToolItem struct contains only private data. It should only be accessed through the functions described below.

## Property Details

### The `“is-important”` property

      “is-important”             gboolean

Whether the toolbar item is considered important. When TRUE, toolbar buttons show text in GTK_TOOLBAR_BOTH_HORIZ mode.

Flags: Read / Write

Default value: FALSE

### The `“visible-horizontal”` property

      “visible-horizontal”       gboolean

Whether the toolbar item is visible when the toolbar is in a horizontal orientation.

Flags: Read / Write

Default value: TRUE

### The `“visible-vertical”` property

      “visible-vertical”         gboolean

Whether the toolbar item is visible when the toolbar is in a vertical orientation.

Flags: Read / Write

Default value: TRUE

## Signal Details

### The `“create-menu-proxy”` signal

    gboolean
    user_function (GtkToolItem *tool_item,
                   gpointer     user_data)

This signal is emitted when the toolbar needs information from `tool_item` about whether the item should appear in the toolbar overflow menu. In response the tool item should either

- call `gtk_tool_item_set_proxy_menu_item()` with a `NULL` pointer and return `TRUE` to indicate that the item should not appear in the overflow menu
- call `gtk_tool_item_set_proxy_menu_item()` with a new menu item and return `TRUE`, or
- return `FALSE` to indicate that the signal was not handled by the item. This means that the item will not appear in the overflow menu unless a later handler installs a menu item.

The toolbar may cache the result of this signal. When the tool item changes how it will respond to this signal it must call `gtk_tool_item_rebuild_menu()` to invalidate the cache and ensure that the toolbar rebuilds its overflow menu.

#### Parameters

tool_item | the object the signal was emitted on |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the signal was handled, `FALSE` if not

Flags: Run Last

### The `“set-tooltip”` signal

    gboolean
    user_function (GtkToolItem *tool_item,
                   GtkTooltips *tooltips,
                   gchar       *tip_text,
                   gchar       *tip_private,
                   gpointer     user_data)

This signal is emitted when the toolitem's tooltip changes. Application developers can use `gtk_tool_item_set_tooltip()` to set the item's tooltip.

`GtkToolItem::set-tooltip` has been deprecated since version 2.12 and should not be used in newly-written code.

With the new tooltip API, there is no need to use this signal anymore.

#### Parameters

tool_item | the object the signal was emitted on |
tooltips | the GtkTooltips |
tip_text | the tooltip text |
tip_private | the tooltip private text |
user_data | user data set when the signal handler was connected. |

#### Returns

`TRUE` if the signal was handled, `FALSE` if not

Flags: Run Last

### The `“toolbar-reconfigured”` signal

    void
    user_function (GtkToolItem *tool_item,
                   gpointer     user_data)

This signal is emitted when some property of the toolbar that the item is a child of changes. For custom subclasses of GtkToolItem, the default handler of this signal use the functions

- `gtk_tool_shell_get_orientation()`
- `gtk_tool_shell_get_style()`
- `gtk_tool_shell_get_icon_size()`
- `gtk_tool_shell_get_relief_style()`

to find out what the toolbar should look like and change themselves accordingly.

#### Parameters

tool_item | the object the signal was emitted on |
user_data | user data set when the signal handler was connected. |

Flags: Run Last
