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;
T * make_managed(T_Args &&... args)
Create a Gtk::Object such as a widget and Gtk::manage() it in a single step.
Definition object.h:63

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