Does anyone understand how to program
the procedure Properties.Property.IntersectWith?

To be specific suppose I have a type WidgetProperty
with a field p.widget. Further suppose widget is some
constant (maybe 2).

Image I have two properties p & q, and widget is in
all of p.known, p.valid, q.known, & q.valid. Further
suppose p.widget is blue and q.widget is blue.

What does IntersectWith do?


Seems easy?

Maybe p.known is unchanged, p.valid is unchanged,
and equal := TRUE?


Now for the hard bit.

What if widget is in one of p.readOnly and q.readOnly,
but NOT in the other?


Cheers

Robert
