## 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.

## set_activatable()

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

Makes the cell renderer activatable.

Since gtkmm 2.18:

Parameters

  setting | The value to set.

## set_active()

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

Activates or deactivates a cell renderer.

Parameters

  setting | The value to set.

## set_radio()

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.

## signal_toggled()

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

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

Flags: Run Last

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

It is the responsibility of the application to update the model with the correct value to store at path. Often this is simply the opposite of the value currently stored at path.

Parameters

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

## Friends And Related Function Documentation

## wrap()

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.
