Hey, you got it! Neither $tmp nor $valor were, of course, a reference (in fact, I insisted on evaluating and dereferencing $dades to get the scalar value... poor fool of me ;P). I did check the C Gtk manual, and saw that in C a pointer had to be passed to the function, but I simply ignored it.

By set_row_data()ing the whole big arrayref $dades this stuff seems to work.

while (1) {
print "Many thanks dude! :-))";
}
