ToggleButton

open class ToggleButton : Button, ToggleButtonProtocol

A GtkToggleButton is a GtkButton which will remain “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().

CSS nodes

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

Creating two GtkToggleButton widgets.

(C Language Example):

static void output_state (GtkToggleButton *source, gpointer user_data) {
  printf ("Active: %d\n", gtk_toggle_button_get_active (source));
}

void make_toggles (void) {
  GtkWidget *window, *toggle1, *toggle2;
  GtkWidget *box;
  const char *text;

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

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

  // Makes this toggle button invisible
  gtk_toggle_button_set_mode (GTK_TOGGLE_BUTTON (toggle1),
                              TRUE);

  g_signal_connect (toggle1, "toggled",
                    G_CALLBACK (output_state),
                    NULL);
  gtk_container_add (GTK_CONTAINER (box), toggle1);

  text = "Hi, I’m a toggle button.";
  toggle2 = gtk_toggle_button_new_with_label (text);
  gtk_toggle_button_set_mode (GTK_TOGGLE_BUTTON (toggle2),
                              FALSE);
  g_signal_connect (toggle2, "toggled",
                    G_CALLBACK (output_state),
                    NULL);
  gtk_container_add (GTK_CONTAINER (box), toggle2);

  gtk_container_add (GTK_CONTAINER (window), box);
  gtk_widget_show_all (window);
}

The ToggleButton type acts as a reference-counted owner of an underlying GtkToggleButton instance. It provides the methods that can operate on this data type through ToggleButtonProtocol conformance. Use ToggleButton as a strong reference or owner of a GtkToggleButton instance.
