I just tested with Delphi and it works there as well. So contrary to
what we thought this does not seem to be a bug...
What does Delphi do with
property Foo[AIndex: Integer; BIndex: Integer = 0]: Integer read
GetFoo;
Because FPC rejects this one. (And IMHO rightfully so)
Assuming that GetFoo is declared as "function GetFoo(AIndex: Integer):
Integer" It fails with "E2250: There is no overloaded variant of
'GetFoo' that can be called with these arguments" (or however that error
message is translated to English.
The following also fails:
=== code begin ===
function GetFoo(AIndex: Integer; BIndex: Integer): Integer;
property Foo[AIndex: Integer; BIndex: Integer = 0]: Integer read GetFoo;
=== code end ===
However this works:
=== code begin ===
function GetFoo(AIndex: Integer; BIndex: Integer = 0): Integer;
property Foo[AIndex: Integer; BIndex: Integer = 0]: Integer read GetFoo;
=== code end ===
As does this:
=== code begin ===
function GetFoo(AIndex: Integer; BIndex: Integer = 0): Integer;
property Foo[AIndex: Integer; BIndex: Integer]: Integer read GetFoo;
=== code end ===

Sven
