References in GtkBuilder interface files

[Martin Kalbfuß <ma kalbfuss web de>]

Hi,

I would like to put one object into two container widgets inside an
interface file. There should be only one instance of the object, and the
other only a reference. Is something like this possible?

I like to have a Container widget as object parameter for the callbacks,
containing all the necessary objects. For example the main window, which
is already a member of the widget hierarchy.

Thanks
