## Implemented Interfaces

GtkCheckMenuItem implements AtkImplementorIface, GtkBuildable, GtkActivatable and GtkActionable.

## Includes

    #include <gtk/gtk.h>

## Description

A GtkCheckMenuItem is a menu item that maintains the state of a boolean value in addition to a GtkMenuItem 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.

GtkCheckMenuItem has a main CSS node with name menuitem, and a subnode with name check, which gets the .left or .right style class.

## Functions

### 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.

#### Parameters

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.

#### Parameters

label | The text of the button, with an underscore in front of the character |

#### Returns

a new GtkCheckMenuItem

### 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()`.

#### Parameters

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.

#### Parameters

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

### gtk_check_menu_item_toggled ()

    void
    gtk_check_menu_item_toggled (GtkCheckMenuItem *check_menu_item);

Emits the “toggled” signal.

#### Parameters

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()`.

#### Parameters

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.

#### Parameters

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

#### Parameters

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

#### Parameters

check_menu_item | a GtkCheckMenuItem |

#### Returns

Whether `check_menu_item` looks like a GtkRadioMenuItem

Since: 2.4

## Types and Values

### struct GtkCheckMenuItem

    struct GtkCheckMenuItem;

### struct GtkCheckMenuItemClass

    struct GtkCheckMenuItemClass {
      GtkMenuItemClass parent_class;

      void (* toggled)	  (GtkCheckMenuItem *check_menu_item);
      void (* draw_indicator) (GtkCheckMenuItem *check_menu_item,
    			   cairo_t          *cr);
    };

#### Members

`toggled` () | Signal emitted when the state of the check box is changed. |
`draw_indicator` () | Called to draw the check indicator. |

## Property Details

### The `“active”` property

      “active”                   gboolean

Whether the menu item is checked.

Owner: GtkCheckMenuItem

Flags: Read / Write

Default value: FALSE

### The `“draw-as-radio”` property

      “draw-as-radio”            gboolean

Whether the menu item looks like a radio menu item.

Flags: Read / Write

Default value: FALSE

### The `“inconsistent”` property

      “inconsistent”             gboolean

Whether to display an "inconsistent" state.

Owner: GtkCheckMenuItem

Flags: Read / Write

Default value: FALSE

## Style Property Details

### The `“indicator-size”` style property

      “indicator-size”           int

The size of the check or radio indicator.

`GtkCheckMenuItem:indicator-size` has been deprecated since version 3.20 and should not be used in newly-written code.

## Signal Details

### The `“toggled”` signal

    void
    user_function (GtkCheckMenuItem *checkmenuitem,
                   gpointer          user_data)

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

A signal handler can use `gtk_check_menu_item_get_active()` to discover the new state.

#### Parameters

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

Flags: Run First
