hm... yes i thought of that, too, but i would expect that a function
which is as basic as gtk_signal_connect should provide some way of
passing multiple args. i have this problem quite often and defining a
struct every time doesn't seem the most elegant way... however, i'll
make use of your suggestion as i can't think for a better solution for
myself. by the way, is it possible creating and passing a struct on the
fly (in the call of gtk_signal_func)? it wouldn't probably look that
nice but saves lines ;)

at least it seems my question wasn't that silly =)

best wishes,
