Hi, Robert, I'm sorry, but I see no easy option to do this task.
But perhaps someone else have a solution about this. I'm not familiar with it, but perhaps you could use a technique like binding extra arguments in signal handlers. Described hiere: http://gtkmm.org/docs/gtkmm-2.4/docs/tutorial/html/sec-binding-extra-arguments.html You can bind extra agruments through the signal proxy in Gtkmm, wich, as far as I know also template-based. If I'm wrong feel free to correct Me.
