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 #GtkToggleButton 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);
gtk_signal_connect (GTK_OBJECT (toggle1), "toggled",
GTK_SIGNAL_FUNC (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);
gtk_signal_connect (GTK_OBJECT (toggle2), "toggled",
GTK_SIGNAL_FUNC (output_state), NULL);
gtk_box_pack_start (GTK_BOX (GTK_DIALOG(dialog)->action_area),
toggle2, FALSE, FALSE, 2);
gtk_widget_show_all (dialog);
}

The #GtkToggleButton struct contains private data only, and should be manipulated using the functions below.
Creates a new toggle button. A widget should be packed into the button, as in gtk_button_new().
@Returns: a new toggle button.
Creates a new toggle button with a text label.
@label: a string containing the message to be placed in the toggle button.
@Returns: a new toggle button.
Determines whether or not the toggle button is drawn on screen. The default mode is FALSE, which results in the button being displayed. To make the button invisible, set draw_indicator to TRUE.
@toggle_button: a #GtkToggleButton.
@draw_indicator: TRUE or FALSE.
This is a deprecated macro, and is only maintained for compatability reasons.
Changes the state of the toggle button.
@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.
@toggle_button: a #GtkToggleButton.
@is_active: TRUE or FALSE.
Should be connected if you wish to perform an action whenever the
#GtkToggleButton's state is changed.
@togglebutton: the object which received the signal.
Sets whether the toggle button should be pressed in or not.
A value of TRUE causes the toggle button to be invisible. FALSE displays it
again.
