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:

bool first_tab_tab_expand = notebook.property_tab_expand(first_tab_widget);
notebook.property_tab_expand(first_tab_widget) = true ;

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