## Detailed Description

Renders a toggle button in a cell.

The button is drawn as a radio- or checkbutton, depending on the radio property. When activated, it emits the toggled signal.

  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

void Gtk::CellRendererToggle::set_activatable | ( | bool | setting = `true` | ) |

Makes the cell renderer activatable.

Since gtkmm 2.18:

Parameters

  setting | The value to set.

void Gtk::CellRendererToggle::set_active | ( | bool | setting = `true` | ) |

Activates or deactivates a cell renderer.

Parameters

  setting | The value to set.

void Gtk::CellRendererToggle::set_radio | ( | bool | radio = `true` | ) |

If radio is `true`, the cell renderer renders a radio toggle (i.e. a toggle in a group of mutually-exclusive toggles).

If `false`, it renders a check toggle (a standalone boolean option). This can be set globally for the cell renderer, or changed just before rendering each cell in the model (for Gtk::TreeView, you set up a per-row setting using Gtk::TreeViewColumn to associate model columns with cell renderer properties).

Parameters

  radio | `true` to make the toggle look like a radio button.

Glib::SignalProxy1< void,const Glib::ustring& > Gtk::CellRendererToggle::signal_toggled | ( |  | ) |

Slot Prototype:
  `void on_my_toggled(const Glib::ustring& path)`

The signal_toggled() signal is emitted when the cell is toggled.

Parameters

  path | String representation of Gtk::TreePath describing the event location.

## Friends And Related Function Documentation

Gtk::CellRendererToggle* wrap | ( | GtkCellRendererToggle * | object,
|  | bool | take_copy = `false`
| ) |  |
| related

A Glib::wrap() method for this object.

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.
