Detailed Description

template<class T>

class Glib::PropertyProxy< T >

A PropertyProxy can be used to get and set the value of an object's property.

There are usually also get and set methods on the class itself, which you might find more convenient. With the PropertyProxy, you may use either get_value() and set_value(), or operator=() and operator PropertyType(), like so:

 int height = cellrenderer.property_height();
 cellrenderer.property_editable() = true;

You may also receive notification when a property's value changes, by connecting to signal_changed().

You may register new properties for your class (actually for the underlying GType) simply by adding a PropertyProxy instance as a class member. However, your constructor must call the Glib::ObjectBase constructor with a new GType name, in order to register a new GType.
