Delphi, Pointers to procedures
This code works :
bde_name.OnKeyDown:=bde_na
But when i Try to do the same thing with a pointer it fails:
procedure Tfrm_Jobbsiter.Button3Clic
var
p : TProcedure;
begin
p:=bde_nameKeyDown;
bde_name.OnKeyDown:=p;
end;
How is this done correctly?

p should be declared "procedure of object" instead of TProcedure

Theax, but then i get "E2009 Incompatible types: 'Parameter lists differ"
-
In the working example i dont have to handle the parameters, and that is the point :P

Very nice, but I guess the TKeyDown is not implemented in my old rad studio 2007.
@ cyberkiwi,
Where did you come with that TKeyDown from? I do not think that's in Delphi at all.
If it's there what is the ideal use of it?
