Hi all.
I was given to understand that there can only be one default button. I see I am
mistaken. I thought that setting the defaultButton of a card unset the default
of the button that was the defaultButton prior to that. It seems to me that
this is how this ought to work, because if not, then the return key will yield
unpredictable results.
What this DOES do is on a standard button it changes the appearance to, for
example on OS X, a blue button instead of a whitish one. Is this all this is
for? It cannot be as hitting the return key WILL send a mouseUp to whatever the
engine thinks is the current defaultButton.
You *can* indeed have more than one default button, but it's not a good
idea. For the reasons you mentioned and more. On OSX having more than
one default button will use up huge amounts of cpu power even while
doing nothing more than sitting around and looking good.
PowerTools will warn you if you try to add more than one default button,
but once you've been warned won't prevent it, because by that point you
obviously mean to do what you're about to do.
