two different signal handlers does not sound to bad.
if you want a common functionto do allthe work then the signal handlers
could be short wrapper functions:
signal_button_1(mixed ... args)
{
button_handler("button_1", @args);
}
signal_button_2(mixed ... args)
{
button_handler("button_2", @args);
}
you could even hide those with inline lambda, and autogeneration of
such functions should also be possible (but not if they have the same
name, unless you add more info)
