Dynamicaly assigning methods

[Adam.Pilorz]

I have a problem. I'm creating a dynamic button (for example like that:

Code: [Select]

var MyButton: TButton;
...
MyButton:=TButton.Create(Self);
MyButton.Top:=2;
MyButton.Left:=2;
MyButton.Width:=200;
MyButton.Height:=28;
MyButton.Caption:='MyButton';)
And now how to assign a method to a dynamic button? Such thing should work:

Code: [Select]

MyButton.OnClick:=MyForm.MyButtonClick;
Unfortunately, it doesn't do anything except halting compilation and calling an error: Wrong number of parameters... Of course, compiler is trying to assign a return value of MyButtonClick method. How to solve this problem??

MyButton.OnClick:=@WhateverIsTheMethodsName should do the trick. I had the same problem and that was the solution.

Unfortunately, it ends with an error: Incopatible types: got "<address of procedure(TObject) of Object;Register>" expected "<procedure variable type of procedure(TObject) of Object;Register>"

This might be a compiler bug. What compiler version are you using?

[Adam.Pilorz]

I'm using FPC 1.9.5 (2004/10/04). Should I change it??

is TObject redeclared ? (are you still using {$mode objfpc} )

[Adam.Pilorz]

{$mode objfpc} is in every main program. Shouldn't it?

[Marc]

afaik in every unit
