Detailed Description
template<class T>
class Gtk::ChildPropertyProxy< T >
A ChildPropertyProxy can be used to get and set the value of a GtkContainer's child property.
Child properties are not specific to either the container or the contained widget, but rather to their relation. With the ChildPropertyProxy, you may use either get_value() and set_value(), or operator=() and operator PropertyType(), like in this example:
You may also receive notification when a property's value changes on a child, by connecting to signal_changed().
