Move component

I update the left value of another component, when the left value of my groupbox component is changed.
If I move the groupbox component around in the delphi IDE, the left value change fine. But the left value of the other component isn't changed.

If I then focus the left property in the object inspector and hits enter, the left value of the second component is updated.
Is there a way to update the second components value on the fly ? or is this just the way delphi works

Why don't you make all other components children of your groupbox? That way Windows will take care of moving (but I admit, the "Left" property of all children will be relative to the parent).

The suggestion you got from geobul in http://www.experts-exchange.com/jsp/qShow.jsp?qid=20164439 is not entirely reliable since the Left property is used in VCL at a lower level than your new-defined SetLeft (which does not fall propely over a virtual method but is merely a replacement from that point on to other derivates).

Check my last post on http://www.experts-exchange.com/jsp/qShow.jsp?ta=delphi&qid=20164523 for some other suggestion.
