Hi,

I tried to include a TTimer in my basic component.
If I create an instance of my component, I get the following error:
(translated form Dutch)


Application error:
Cannot get the property ttimer_setenabled of a not defined or empty value

What is my mistake here?


type
TCell = class(TPanel)
  private
  aTimer   :TTimer;
  public
  constructor Create(AOwner: TComponent); override;
  destructor Destroy; override;

  end;

implementation

constructor TCell.Create(AOwner: TComponent);
begin
inherited Create(AOwner);
aTimer.Enabled:=false;
end;


destructor TCell.Destroy;
begin
inherited Destroy;
end;

Same as with Delphi - you have to create the timer in your constructor.

I know, but I can not create an instance of TTimer (aTimer:=TTimer.Create
This does not exist for TTimer.

The framework source shows that TAnimator.Create does exactly that:
FTimer:=TTimer.Create(nil);

Indeed the webcore.wbs code shows that there is a Create for TTimer, so I don't
know what your problem is.

Oh, stupid me! I walked in that trap a few times before.

Your answer reminded me of the fact that indeed TTimer.Create does not
exist, but TTimer.Create(nil) does exist! This got me on the wrong foot
before. Instead of giving a syntaxerror EWB tells me the method does not
exist.

Thanks!
