The problem here is a method is just a function - one that takes an extra first parameter. You could do something like $mw->Button(command => $self->can('func1'))->pack; but then the method will be called as a simple function without $self passed to it - nor of course any other parameters you might need. So if you want to stick by this route, you'll have to pass a closure, as tadman suggested: $mw->Button(command => sub { $self->func1($a, @_) })->pack;

Keep in mind that OO in Perl is different from OO in other languages. One advantage that Perl offers is that it has closures; using them, you can emulate just about any behaviour you want to.

I find OO in Perl is actually more flexible and powerful than OO in OO languages, with one painfully significant exception: no clean methodology to data inheritance.
