gtk:widget-class-bind-template-child (gtype name)

gtype -- a g:type-t type ID for the widget class
name -- a string for the ID of the child defined in the template XML

Binds a child widget defined in a template to the widget class of type gtype. Automatically assigns an object declared in the class template XML to be set accessible via the gtk:widget-template-child function.

Note that this must be called from a composite widget class initializer after calling the gtk:widget-class-set-template function. See the gtk:widget-init-template documentation for an example.
