Description: Reference for Gtk.ToggleButton

### Class

# GtkToggleButton

#### Description [src]

    class Gtk.ToggleButton : Gtk.Button {
      /* No available fields */
    }

A `GtkToggleButton` is a button which remains “pressed-in” when clicked.

Clicking again will cause the toggle button to return to its normal state.

A toggle button is created by calling either `gtk_toggle_button_new()` or `gtk_toggle_button_new_with_label()`. If using the former, it is advisable to pack a widget, (such as a `GtkLabel` and/or a `GtkImage`), into the toggle button’s container. (See `GtkButton` for more information).

The state of a `GtkToggleButton` can be set specifically using `gtk_toggle_button_set_active()`, and retrieved using `gtk_toggle_button_get_active()`.

To simply switch the state of a toggle button, use `gtk_toggle_button_toggled()`.

## Grouping

Toggle buttons can be grouped together, to form mutually exclusive groups - only one of the buttons can be toggled at a time, and toggling another one will switch the currently toggled one off.

To add a `GtkToggleButton` to a group, use `gtk_toggle_button_set_group()`.

## CSS nodes

`GtkToggleButton` has a single CSS node with name button. To differentiate it from a plain `GtkButton`, it gets the `.toggle` style class.

               gtk_button_get_label (GTK_BUTTON (source)),
               gtk_toggle_button_get_active (source) ? "Yes" : "No");
    }

      window = gtk_window_new ();
      box = gtk_box_new (GTK_ORIENTATION_VERTICAL, 12);

      text = "Hi, I’m toggle button one";
      toggle1 = gtk_toggle_button_new_with_label (text);

      g_signal_connect (toggle1, "toggled",
                        G_CALLBACK (output_state),
                        NULL);
      gtk_box_append (GTK_BOX (box), toggle1);

      text = "Hi, I’m toggle button two";
      toggle2 = gtk_toggle_button_new_with_label (text);
      g_signal_connect (toggle2, "toggled",
                        G_CALLBACK (output_state),
                        NULL);
      gtk_box_append (GTK_BOX (box), toggle2);

      gtk_window_set_child (GTK_WINDOW (window), box);
      gtk_widget_show (window);
