Procedures -Delphi

[question]

Hello,

I have one basic question, what is the differene the following procedures:

procedure Test(Sender : Tobject);
Procedure Test();
Procedure Test;


Thanks in advance for your reply

The first procedure has one parameter, while the second and third have none. For those both styles are allowed.

Note that you may also omit the parameters when implementing a method you have already declared. Code completion sometimes does that. You don't have to. And I don't think you should :wink:

Delphi-Quellcode:

interface

[...]
   procedure myProcedure(Sender: TObject);
[...]

implementation

procedure myClass.myProcedure;
begin
   [...]
end;
