Access violation when assigning a value to my component Bitmap property [closed]

Answer 1

Your setter method looks correct, but you're getting an Access Violation because your FStarOff member is nil at the moment.

The usual is to create it at construction time and free it at destruction time.

constructor TMyComponent.Create(AOwner: TComponent);
begin
  inherited;
  FStarOff := TBitmap.Create;
end;

destructor TMyComponent.Destroy;
begin
  FStarOff.Free;
  inherited;
end;
