TPanel + OnMouseUp

[horizon]

Hello,

i try to use the TPanel Component and the Event OnMouseUp.
But the IDE shows the error:

wrong number or parameters specified


but i think the parameters are correct...

procedure   HandleOnMouseUp(Sender: TObject; Button: TMouseButton; Shift: TShiftState; X, Y: Integer);

can you help me?  :?:

If you mean that you're trying to assign the event handler in your code, then you either need to do it like this:

Panel1.OnMouseUp := @HandleOnMouseUp;

or you need to use the compiler switch to go to Delphi mode.

You cannot just use any procedure as a event handler. You have to make HandleOnMouseUp a method of a object.
