Hi, Below is from the Kylix 3 help.
--------------------------[ copy ]------------------------------ Type identity is almost straightforward. When one type identifier is declared using another type identifier, without qualification, they denote the same type. Thus, given the declarations type T1 = Integer; T2 = T1; T3 = Integer; T4 = T2; T1, T2, T3, T4, and Integer all denote the same type. To create distinct types, repeat the word type in the declaration. For example, type TMyInteger = type Integer;creates a new type called TMyInteger which is not identical to Integer. --------------------------[ end ]------------------------------ So when am I supposed to use type TfpgColor = longword; vs type TfpgColor = type longword; ??? What's the actual difference between them? I have used the first option (declaration) in the fpGUI project. For things like: const clBlue = TfpgColor($0000FF); Is the above the same as what the Free Pascal documentation describes below? Or is this something different? --------------------------[ copy ]------------------------------ The last class, type identifier, is just a means to give another name to a type. This presents a way to make types platform independent, by only using these types, and then defining these types for each platform individually. The programmer that uses these units doesn't have to worry about type size and so on. --------------------------[ end ]------------------------------ Regards, - Graeme - _______________________________________________ fpGUI - a cross-platform Free Pascal GUI toolkit http://opensoft.homeip.net/fpgui/ _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
