Hello,
I have two questions regarding class Abstract:
1. From what version of FPC does it support ?
At least 2.4.2 supports it. It might be 2.4.0 as well (I don't know that
for sure though).
2. Can I inherit from a class and the new class that I declare can be
set as abstract ?
I mean
TClassA = class abstract
...
end;
TClassB = Class(TClassA) abstract ?
If so, then what am I missing here? FPC (2.5.1) tell me that it is
expecting ":", but "abstract" was found.
The "abstract" needs to be put after the "class" and before the parent
class (it's strange, but the way Borland has decided things are done...):
TClassB = class abstract(TClassA)
Regards,
Sven
