In our previous episode, Sven Barth said:
As is today, if you have a reference to a IFPObserver is not possible
to use it to attach to, e.g., child objects. This occurs because AFAIK
you can't get a TObject from a interface reference.
At least for COM interfaces "as" and "is" with a class type on the right
side is supported. The corresponding code for Corba interfaces is not
implemented (yet). This feature exists at least since 2.6.0.
Also: You can get a tcomponent though, if you implement
IInterfaceComponentreference
TComponent implements this.
I haven't tested that, but does "SomeCorbaInterface as SomeCOMInterface"
work? Because maybe the IInterfaceComponentReference trick would only
work if the interface I'm working on is also a COM interface (because it
could rely on the existence of QueryInterface)...
Regards,
Sven
