I simply used the Browser's Print menu option, instead of the "printer friendly webpage option", and that worked fine for my needs. > Regarding the observer pattern, I'll refer you to this stack overflow > question: > > http://stackoverflow.com/questions/550785/c-events-or-an-observer-interface-pros-cons > > My take is that event are more natural and that they are probably more > well established than the pattern of creating an interface to subscribe Regarding that stackoverlflow question. That is highly dependant on how you implemented the observer in your BOM. Years ago, I implemented a observer via Interfaces in our Object Pascal code, where I could observe just the fields of a class I was interested in. No generics required, just a plain observer implementation using a InterfaceList - by creating a base BOM class which all your other BO descend from. I'm not saying your idea or implementation is bad - though personally I have never had the need to use generics yet (and it seems neither has many others - good or bad language feature, I don't know?). I'm just pointing out that there are multiple ways of doing the same thing. Observer could very easily be used too, and without the pitfalls listed in the Stack Overflow article. -- Ben. _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
