How do I enable a button?

[FishingIwishIwas]

I setup a button with a dis-able state initially:

$Bt_Done = $Frame->Button(-text => 'Done',
-state => 'disabled'
...)

and want to enable it later in another routine but I couldn't figure out the way to do that:

$Bt_Done->state = enabled; #This doesn't work
$Bt_Done->state => enabled; #This doesn't work either

What's the right way?
Thanks!

$Bt_Done->configure(-state => normal);

Cheers,
