# 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
virtual | ~CheckMenuItem ()
GtkCheckMenuItem* | gobj ()
| Provides access to the underlying C GtkObject.
const GtkCheckMenuItem* | gobj () const
| Provides access to the underlying C GtkObject.
| CheckMenuItem ()
| CheckMenuItem (const Glib::ustring& label, bool mnemonic=false)
void | set_active (bool state=true)
bool | get_active () const
| Returns whether the check menu item is active.
void | toggled ()
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.
bool | get_inconsistent () const
| Retrieves the value set by set_inconsistent().
Glib::SignalProxy0<void> | signal_toggled ()
Glib::PropertyProxy<bool> | property_active ()
| You rarely need to use properties because there are get_ and set_ methods for almost all of them.
Glib::PropertyProxy<bool> | property_inconsistent ()
| You rarely need to use properties because there are get_ and set_ methods for almost all of them.

## Member Function Documentation

virtual void Gtk::CheckMenuItem::draw_indicator_vfunc | ( | GdkRectangle* | area | ) | `[protected, virtual]`

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_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.

virtual void Gtk::CheckMenuItem::on_toggled | ( |  | ) | `[protected, virtual]`

Glib::PropertyProxy<bool> Gtk::CheckMenuItem::property_active | ( |  | ) |

| You rarely need to use properties because there are get_ and set_ methods for almost all of them. Returns: A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<bool> Gtk::CheckMenuItem::property_inconsistent | ( |  | ) |

| You rarely need to use properties because there are get_ and set_ methods for almost all of them. Returns: A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

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

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 | ( |  | ) |
