## ◆ property_group()

Glib::PropertyProxy_WriteOnly< CheckButton* > Gtk::CheckButton::property_group | ( |  | ) |

The check button whose group this widget belongs to.

Returns
  A PropertyProxy_WriteOnly that allows you to set the value of the property, or receive notification when the value of the property changes.

## ◆ property_inconsistent() [1/2]

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

If the check button is in an “in between” state.

The inconsistent state only affects visual appearance, not the semantics of the button.

Default value: `false`

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

## ◆ property_inconsistent() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gtk::CheckButton::property_inconsistent | ( |  | ) | const

If the check button is in an “in between” state.

The inconsistent state only affects visual appearance, not the semantics of the button.

Default value: `false`

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

## ◆ property_label() [1/2]

Glib::PropertyProxy< Glib::ustring > Gtk::CheckButton::property_label | ( |  | ) |

Text of the label inside the check button, if it contains a label widget.

Default value: ""

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

## ◆ property_label() [2/2]

Glib::PropertyProxy_ReadOnly< Glib::ustring > Gtk::CheckButton::property_label | ( |  | ) | const

Text of the label inside the check button, if it contains a label widget.

Default value: ""

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

## ◆ property_use_underline() [1/2]

Glib::PropertyProxy< bool > Gtk::CheckButton::property_use_underline | ( |  | ) |

If set, an underline in the text indicates that the following character is to be used as mnemonic.

Default value: `false`

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

## ◆ property_use_underline() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gtk::CheckButton::property_use_underline | ( |  | ) | const

If set, an underline in the text indicates that the following character is to be used as mnemonic.

Default value: `false`

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

## ◆ set_active()

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

Changes the check buttons active state.

Parameters

  setting | The new value to set.

## ◆ set_child()

void Gtk::CheckButton::set_child | ( | Widget & | child | ) |

Sets the child widget of button.

Note that by using this API, you take full responsibility for setting up the proper accessibility label and description information for button. Most likely, you'll either set the accessibility label or description for button explicitly, or you'll set a labelled-by or described-by relations from child to button.

Since gtkmm 4.8:

Parameters

  child | The child widget.

## ◆ set_group()

void Gtk::CheckButton::set_group | ( | CheckButton & | group | ) |

Adds self to the group of group.

In a group of multiple check buttons, only one button can be active at a time. The behavior of a checkbutton in a group is also commonly known as a radio button.

Setting the group of a check button also changes the css name of the indicator widget's CSS node to 'radio'.

Setting up groups in a cycle leads to undefined behavior.

Note that the same effect can be achieved via the Gtk::Actionable API, by using the same action with parameter type and state type 's' for all buttons in the group, and giving each button its own target value.

Parameters

  group | Another `Gtk::CheckButton` to form a group with.

## ◆ set_inconsistent()

void Gtk::CheckButton::set_inconsistent | ( | bool | inconsistent = `true` | ) |

Sets the `Gtk::CheckButton` to inconsistent state.

You shoud turn off the inconsistent state again if the user checks the check button. This has to be done manually.

Parameters

  inconsistent | `true` if state is inconsistent.

## ◆ set_label()

void Gtk::CheckButton::set_label | ( | const Glib::ustring & | label | ) |

Sets the text of self.

If property_use_underline() is `true`, an underscore in label is interpreted as mnemonic indicator, see set_use_underline() for details on this behavior.

Parameters

  label | The text shown next to the indicator, or `nullptr` to show no text.

## ◆ set_use_underline()

void Gtk::CheckButton::set_use_underline | ( | bool | setting = `true` | ) |

Sets whether underlines in the label indicate mnemonics.

If setting is `true`, an underscore character in self's label indicates a mnemonic accelerator key. This behavior is similar to Gtk::Label::property_use_underline().

Parameters

  setting | The new value to set.

## ◆ signal_toggled()

Glib::SignalProxy<void()> Gtk::CheckButton::signal_toggled | ( |  | ) |

Slot Prototype:
  `void on_my_toggled()`

Flags: Run First

Emitted when the buttons's property_active() property changes.

## ◆ unset_child()

void Gtk::CheckButton::unset_child | ( |  | ) |

## ◆ unset_group()

void Gtk::CheckButton::unset_group | ( |  | ) |

## Friends And Related Function Documentation

## ◆ wrap()
