GtkToggleButton
create buttons which retain their state.
A #GtkToggleButton is a #GtkButton which will remain 'pressed-in' when
clicked. Clicking again will cause the toggle button to return to it's
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 #GtkPixmap), 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.
Creating two <structname>GtkToggleButton</structname> widgets.
void make_toggles (void) {
GtkWidget *dialog, *toggle1, *toggle2;
dialog = gtk_dialog_new ();
toggle1 = gtk_toggle_button_new_with_label ("Hi, i'm a toggle button.");
/* Makes this toggle button invisible */
gtk_toggle_button_set_mode (GTK_TOGGLE_BUTTON (toggle1), TRUE);
g_signal_connect (GTK_OBJECT (toggle1), "toggled",
G_CALLBACK (output_state), NULL);
gtk_box_pack_start (GTK_BOX (GTK_DIALOG (dialog)->action_area),
toggle1, FALSE, FALSE, 2);
toggle2 = gtk_toggle_button_new_with_label ("Hi, i'm another toggle button.");
gtk_toggle_button_set_mode (GTK_TOGGLE_BUTTON (toggle2), FALSE);
g_signal_connect (GTK_OBJECT (toggle2), "toggled",
G_CALLBACK (output_state), NULL);
gtk_box_pack_start (GTK_BOX (GTK_DIALOG (dialog)->action_area),
toggle2, FALSE, FALSE, 2);
gtk_widget_show_all (dialog);
}

This is a deprecated macro, and is only maintained for compatibility reasons.
Emits the toggled
signal on the #GtkToggleButton. There is no good reason for an
application ever to call this function.
@toggle_button: a #GtkToggleButton.
Queries a #GtkToggleButton and returns it's current state. Returns %TRUE if
the toggle button is pressed in and %FALSE if it is raised.
@toggle_button: a #GtkToggleButton.
@Returns: a #gboolean value.
Sets the status of the toggle button. Set to %TRUE if you want the
GtkToggleButton to be 'pressed in', and %FALSE to raise it.
This action causes the toggled signal to be emitted.
