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.

Creating two `GtkToggleButton` widgets.

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

  text = "Hi, I’m a toggle button.";
  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 a toggle button.";
  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);
}
