/**
* A #GPropertyAction is a way to get a #GAction with a state value
* reflecting and controlling the value of a #GObject 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 #GVariant 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). #GPropertyAction 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 #GAction 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
* #GSettings. In that case, the real source of the value is
* #GSettings. If you want a #GAction to control a setting stored in
* #GSettings, see g_settings_create_action() instead, and possibly
* combine its use with g_settings_bind().
*
* Since: 2.38
