What's the correct type to ensure portability in this case?Use "Find declaration" to find out: procedure QueueAsyncCall(const AMethod: TDataEvent; Data: PtrInt); TDataEvent = procedure (Data: PtrInt) of object; Or simply let the IDE generate the method for you: 1. type the line Application.QueueAsyncCall(@MyFunc, Param); 2. place cursor on MyFunc 3. press complete code (Ctrl+Shift+C) This will create the method procedure MyFunc(Data: PtrInt);
Thanks, I was in the middle of tracking down TDataEvent :-) -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] -- _______________________________________________ Lazarus mailing list [email protected] http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
