Re: GtkBuilder and callbacks.

[Martin Kalbfuß <ma kalbfuss web de>]

I used a structure like you before I realized, that I can register the
callbacks inside my Builder file. This is nice. I can add a object
property to pass an ID to the callback. But what if I need more then one
id passed to the callback. Is there an easy way to do this inside the
xml file?

thanks.
