Do widgets even have the capability to send a message and have it return back to the widget if it is "Pass"ed in the spirit of "Pre" messages?

you would have a property for autohilite, and if that is false, the developer would be responsible for setting the hilite. that's the way it's implemented with other controls.

On the first day, God created the heavens and the Earth On the second day, God created the oceans.
On the third day, God put the animals on hold for a few hours,
   and did a little diving.
And God said, "This is good."
