## 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().
