DoDi,
in principle your are right,
we can store the data for later processing,
so, we can evaluate the results more slowly.
That way we can evaluate another more sophisticated
and time consuming algorithms for clustering by similarity...
You're absolutely right!
I can not wait to explain that to my boss!


Good luck :-)


I found a Lock procedure that applies to GraphicalObject in the Help

procedure Lock;
Description
Blocks other execution threads from using the associated canvas until the Unlock method is called.

I was thinking about a different method, preventing Windows from sending paint messages. Something like the LockWindowUpdate API, but not exactly that. It depends on your intention and implementation of the painting, whether such a procedure is required at all.

Une Bonne Année souhaite
