# Gtk::CheckMenuItem Class Reference
[Widgets, Menu classes]

Inheritance diagram for Gtk::CheckMenuItem:

[legend]
List of all members.

## Detailed Description

A menu item that maintains the state of a boolean value in addition to a Gtk::MenuItem'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 Gtk::MenuItem. Activating the Gtk::MenuItem toggles the value.

## Public Member Functions
| CheckMenuItem (const Glib::ustring& label, bool mnemonic=false)
| CheckMenuItem ()
bool | get_active () const
| Returns whether the check menu item is active.
bool | get_draw_as_radio () const
| Returns whether check_menu_item looks like a Gtk::RadioMenuItem.
bool | get_inconsistent () const
| Retrieves the value set by set_inconsistent().
const GtkCheckMenuItem* | gobj () const
| Provides access to the underlying C GtkObject.
GtkCheckMenuItem* | gobj ()
| Provides access to the underlying C GtkObject.
void | set_active (bool state=true)
void | set_draw_as_radio (bool draw_as_radio=true)
| Sets whether check_menu_item is drawn like a Gtk::RadioMenuItem.
void | set_inconsistent (bool setting=true)
| 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.

## Member Function Documentation

bool Gtk::CheckMenuItem::get_active | ( |  | ) | const

| Returns whether the check menu item is active. See set_active(). Returns: `true` if the menu item is checked.

bool Gtk::CheckMenuItem::get_draw_as_radio | ( |  | ) | const

| Returns whether check_menu_item looks like a Gtk::RadioMenuItem. Returns: Whether check_menu_item looks like a Gtk::RadioMenuItem Since gtkmm 2.4:

bool Gtk::CheckMenuItem::get_inconsistent | ( |  | ) | const

| Retrieves the value set by set_inconsistent(). Returns: `true` if inconsistent.

const GtkCheckMenuItem* Gtk::CheckMenuItem::gobj | ( |  | ) | const`[inline]`

| Provides access to the underlying C GtkObject. Reimplemented from Gtk::MenuItem. Reimplemented in Gtk::RadioMenuItem.

GtkCheckMenuItem* Gtk::CheckMenuItem::gobj | ( |  | ) | `[inline]`

| Provides access to the underlying C GtkObject. Reimplemented from Gtk::MenuItem. Reimplemented in Gtk::RadioMenuItem.

void Gtk::CheckMenuItem::set_active | ( | bool | state = `true` | ) |

void Gtk::CheckMenuItem::set_draw_as_radio | ( | bool | draw_as_radio = `true` | ) |

  | Sets whether check_menu_item is drawn like a Gtk::RadioMenuItem. Since gtkmm 2.4: Parameters:
  | draw_as_radio | Whether check_menu_item is drawn like a Gtk::RadioMenuItem.

void Gtk::CheckMenuItem::set_inconsistent | ( | bool | setting = `true` | ) |

  | 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, set_inconsistent() only affects visual appearance, it doesn't affect the semantics of the widget. Parameters:
  | setting | `true` to display an "inconsistent" third state check.

Glib::SignalProxy0<void> Gtk::CheckMenuItem::signal_toggled | ( |  | ) |

| Prototype: `void toggled()`

void Gtk::CheckMenuItem::toggled | ( |  | ) |

## Friends And Related Function Documentation

Gtk::CheckMenuItem* wrap | ( | GtkCheckMenuItem* | object,
|  | bool | take_copy = `false`
| ) | `[related]`

  | Parameters:
  | object | The C instance
  | take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.
Returns: A C++ instance that wraps this C instance.
