 |
|
Hi.
Should I inherit my TBO class from TComponent?
If I do this, the only advantage that I will use is that some times I will
create my TBO descendent setting the Owner property to avoid free the
object in the onDestroy of the form.

Is there such a beast as TInterfacedPersistent? I can't find it in Delphi
5...perhaps in a higher version?

In my opinion, you should derive it from TObject if you do not plan to
use interfaces or TInterfacedObject if you will use interfaces. Further,
if
you would like to use those GetProp(...) functions to get access to
properties in runtime, you can derive from TInterfacedPersistent.
