## Description

A GtkCheckMenuItem is a menu item that maintains the state of a boolean value in addition to a GtkMenuItem's usual role in activating application code.

A check box indicating the state of the boolean value is displayed at the left side of the GtkMenuItem. Activating the GtkMenuItem toggles the value.

## Details

### GtkCheckMenuItem

    typedef struct _GtkCheckMenuItem GtkCheckMenuItem;

The GtkCheckMenuItem struct contains the following fields. (These fields should be considered read-only. They should never be set by an application.)

guint active; | TRUE if the check box is active.

### gtk_check_menu_item_new ()

    GtkWidget*          gtk_check_menu_item_new             (void);

Creates a new GtkCheckMenuItem.

Returns : | a new GtkCheckMenuItem.

### gtk_check_menu_item_new_with_label ()

    GtkWidget*          gtk_check_menu_item_new_with_label  (const gchar *label);

Creates a new GtkCheckMenuItem with a label.

`label` : | the string to use for the label.
Returns : | a new GtkCheckMenuItem.

### gtk_check_menu_item_new_with_mnemonic ()

    GtkWidget*          gtk_check_menu_item_new_with_mnemonic
                                                            (const gchar *label);

Creates a new GtkCheckMenuItem containing a label. The label will be created using `gtk_label_new_with_mnemonic()`, so underscores in `label` indicate the mnemonic for the menu item.

`label` : | The text of the button, with an underscore in front of the mnemonic character
Returns : | a new GtkCheckMenuItem

### gtk_check_menu_item_set_state

    #define gtk_check_menu_item_set_state		gtk_check_menu_item_set_active

### Warning

`gtk_check_menu_item_set_state` is deprecated and should not be used in newly-written code. Use `gtk_check_menu_item_set_active()` instead.

Sets the active state of the menu item's check box.

### gtk_check_menu_item_get_active ()

    gboolean            gtk_check_menu_item_get_active      (GtkCheckMenuItem *check_menu_item);

Returns whether the check menu item is active. See `gtk_check_menu_item_set_active()`.

`check_menu_item` : | a GtkCheckMenuItem
Returns : | `TRUE` if the menu item is checked.

### gtk_check_menu_item_set_active ()

    void                gtk_check_menu_item_set_active      (GtkCheckMenuItem *check_menu_item,
                                                             gboolean is_active);

Sets the active state of the menu item's check box.

`check_menu_item` : | a GtkCheckMenuItem.
`is_active` : | boolean value indicating whether the check box is active.

### gtk_check_menu_item_set_show_toggle ()

    void                gtk_check_menu_item_set_show_toggle (GtkCheckMenuItem *menu_item,
                                                             gboolean always);

### Warning

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

Controls whether the check box is shown at all times. Normally the check box is shown only when it is active or while the menu item is selected.

`menu_item` : | a GtkCheckMenuItem.
`always` : | boolean value indicating whether to always show the check box.

### gtk_check_menu_item_toggled ()

    void                gtk_check_menu_item_toggled         (GtkCheckMenuItem *check_menu_item);

Emits the GtkCheckMenuItem::toggled signal.

`check_menu_item` : | a GtkCheckMenuItem.

### gtk_check_menu_item_get_inconsistent ()

    gboolean            gtk_check_menu_item_get_inconsistent
                                                            (GtkCheckMenuItem *check_menu_item);

Retrieves the value set by `gtk_check_menu_item_set_inconsistent()`.

`check_menu_item` : | a GtkCheckMenuItem
Returns : | `TRUE` if inconsistent

### gtk_check_menu_item_set_inconsistent ()

    void                gtk_check_menu_item_set_inconsistent
                                                            (GtkCheckMenuItem *check_menu_item,
                                                             gboolean setting);

If the user has selected a range of elements (such as some text or spreadsheet cells) that are affected by a boolean setting, and the current values in that range are inconsistent, you may want to display the check in an "in between" state. This function turns on "in between" display. Normally you would turn off the inconsistent state again if the user explicitly selects a setting. This has to be done manually, `gtk_check_menu_item_set_inconsistent()` only affects visual appearance, it doesn't affect the semantics of the widget.

`check_menu_item` : | a GtkCheckMenuItem
`setting` : | `TRUE` to display an "inconsistent" third state check

### gtk_check_menu_item_set_draw_as_radio ()

    void                gtk_check_menu_item_set_draw_as_radio
                                                            (GtkCheckMenuItem *check_menu_item,
                                                             gboolean draw_as_radio);

Sets whether `check_menu_item` is drawn like a GtkRadioMenuItem

`check_menu_item` : | a GtkCheckMenuItem
`draw_as_radio` : | whether `check_menu_item` is drawn like a GtkRadioMenuItem

Since 2.4

### gtk_check_menu_item_get_draw_as_radio ()

    gboolean            gtk_check_menu_item_get_draw_as_radio
                                                            (GtkCheckMenuItem *check_menu_item);

Returns whether `check_menu_item` looks like a GtkRadioMenuItem

`check_menu_item` : | a GtkCheckMenuItem
Returns : | Whether `check_menu_item` looks like a GtkRadioMenuItem

Since 2.4

Whether to display an "inconsistent" state.

Default value: FALSE

## Style Property Details

### The `"indicator-size"` style property

      "indicator-size"           gint                  : Read

## Signal Details

### The `"toggled"` signal

    void                user_function                      (GtkCheckMenuItem *checkmenuitem,
                                                            gpointer          user_data)          : Run First

This signal is emitted when the state of the check box is changed.

A signal handler can examine the `active` field of the GtkCheckMenuItem struct to discover the new state.

`checkmenuitem` : | the object which received the signal.
`user_data` : | user data set when the signal handler was connected.
