    /// A [`PropertyAction`][crate::PropertyAction] is a way to get a [`Action`][crate::Action] with a state value
    /// reflecting and controlling the value of a [`glib::Object`][crate::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`).
    ///
    /// 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`][struct@crate::glib::Variant] types are not currently supported.
    ///
    /// If the property is boolean-valued then the action will have a NULL
    /// 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`][crate::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 a [`Action`][crate::Action] corresponding to
    /// the "visible-child-name" property of a `GtkStack` 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
    /// `GtkStack`.
    ///
    /// An anti-example would be binding the "active-id" property on a
    /// `GtkComboBox`. 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 the "visible-child-name"
    /// property of a `GtkStack` if this value is actually stored in
    /// [`Settings`][crate::Settings]. In that case, the real source of the value is
    /// [`Settings`][crate::Settings]. If you want a [`Action`][crate::Action] to control a setting stored in
    /// [`Settings`][crate::Settings], see [`SettingsExt::create_action()`][crate::prelude::SettingsExt::create_action()] instead, and possibly
    /// combine its use with [`SettingsExtManual::bind()`][crate::prelude::SettingsExtManual::bind()].
