It should be as easy as passing a pointer to your int value as 
data. You just need to cast it to void* as that is what is 
expected. More details here:

Btw, from 
https://docs.gtk.org/gobject/func.signal_connect_data.html :

I suppose GtkD guys forced generation of this method. Looks like 
bindings should not have it.
