Anybody know what list classes or arrays are available in FPC? I know the standard TObjectList and TStringList, but I'm pretty sure there must be more 'not so well known' lists available.
contnrs unit?
I'm busy implementing a Objects[ARow, ACol] property for fpGUI's StringGrid component and would like to read up on what efficient list classes or arrays I could possibly use. I'll only be storing Pointers and the StringGrid will *not* be maintaining the lifespan of the Objects being stored. Only their pointers will be stored, so I guess it doesn't need to be a complex list class or pointer array.
You could use variant arrays or two dynamic arrays, but I personally prefer classes. This approach could be reached using a TObjectList instance to hold TObjectList objects, the getter should have something like this:
Result := ((FObjList[ARow] as TObjectList)[ACol] as TYourTargetClass); Hth. -- Joao Morais _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
