/** An Action reflecting a Glib::Object property.
 *
 * A %PropertyAction is a way to get an Action with a state value
 * reflecting and controlling the value of a Glib::Object property.
 *
 * The state of the action will correspond to the value of the property.
 * Changing it will change the property (assuming the requested value
 * matches the requirements as specified in the GParamSpec, used when the
 * property was installed).
 *
 * Only the most common types are presently supported. Booleans are
 * mapped to booleans, strings to strings, signed/unsigned integers to
 * int32/uint32 and floats and doubles to doubles.
 *
 * If the property is an enum then the state will be string-typed and
 * conversion will automatically be performed between the enum value and
 * "nick" string as per the GEnumValue table.
 *
 * Flags types are not currently supported.
 *
 * Properties of object types, boxed types and pointer types are not
 * supported and probably never will be.
 *
 * Properties of Glib::Variant types are not currently supported.
 *
 * If the property is boolean-valued then the action will have a nullptr
 * parameter type, and activating the action (with no parameter) will
 * toggle the value of the property.
 *
 * In all other cases, the parameter type will correspond to the type of
 * the property.
 *
 * The general idea here is to reduce the number of locations where a
 * particular piece of state is kept (and therefore has to be synchronised
 * between). %PropertyAction does not have a separate state that is kept
 * in sync with the property value -- its state is the property value.
 *
 * For example, it might be useful to create an Action corresponding to
 * property_visible_child_name() of a Gtk::Stack so that the current
 * page can be switched from a menu. The active radio indication in the
 * menu is then directly determined from the active page of the Gtk::Stack.
 *
 * An anti-example would be binding property_active_id() on a Gtk::ComboBox.
 * This is because the state of the combobox itself is probably uninteresting
 * and is actually being used to control something else.
 *
 * Another anti-example would be to bind to property_visible_child_name()
 * of a Gtk::Stack if this value is actually stored in Gio::Settings.
 * In that case, the real source of the value is
 * Gio::Settings. If you want an Action to control a setting stored in
 * Gio::Settings, see Gio::Settings::create_action() instead, and possibly
 * combine its use with Gio::Settings::bind().
