[fpc-pascal] A list of CORBA interfaces - how?
Hi, I'm porting some of my old Delphi code which used interfaces extensively. Since I moved to FPC years ago, I liked the idea of CORBA-style interfaces, and mostly use them under FPC projects. Anyway, some of my code used IInterfaceList / TInterfaceList, but that uses IIInterface, which is an alias for IUnknown, which is COM-style interfaces only. What is the equivalent for CORBA style interfaces? Just a TList storing pointers?

You can iterate over TClass.GetInferfaceTable, and if you declare an interface name it'll appear there (I checked). Not sure whether there's some way (or hack) to compare an (unnamed) interface with the VMT pointer there... Best regards, Flávio PS.

Oops, seems I completely misread your post. The problem is cite is the kind of (or exactly) the one you're trying to fix :-$ Thanks for Marcos for pointing that out. -Flávio 2011/9/20 Flávio Etrusco flavio.etru...@gmail.com: On Tue, Sep 20, 2011 at 3:28 AM, Graeme Geldenhuys graemeg.li...@gmail.com wrote: Hi, I'm porting some of my old Delphi code which used interfaces extensively.
