Make your object inherit from an IDLitComponent object,
then you can use the SetPropertyByIdentifier method
to do this. (You probably have to register the properties
you want to set this way, first. See the RegisterProperty
method.) This will work for *any* object, not just object
graphics objects. I use it extensively in the Catalyst
Library.

Cheers,

David
