Class
GtkToggleButton
Description [src]
class Gtk.ToggleButton : Gtk.Button
implements Gtk.Accessible, Gtk.Actionable, Gtk.Buildable, Gtk.ConstraintTarget {
/* No available fields */
}Shows 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().
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.
Accessibility
GtkToggleButton uses the GTK_ACCESSIBLE_ROLE_TOGGLE_BUTTON role.
