I have written a component. This component owns a few classes and I try
to publish some properties of these owned classes. For this purpose I
derived these classes from TPersistent.
In my component class I have pointers to these owned classes but when I
try to publish them (like in the example pie) I get the
message                                        "Not an allowed type"

Does anybody know what's wrong???
Thanks in advance

There's more to publishing classes and properties than just deriving
them from TPersistent. If you define your classes based on classes
already known to the object inspector (i.e. TStringList, for instance or
TFont), it has no problem displaying the class. But otherwise you must
create a property editor for your class.

I wrote a property editor for my class, but I had still the same problem
("not an allowed type"). A few hours later I solved this problem
accidently (it was a problem with one of my header files) and now it's
possible to publish the properties of the owned classes!!! (I have
another problem now, but that's another story)

Thank you for the hint with the property editor!!! It helped much!
