Dear  Experts,

I have made a TCustomPanel-component and in that component i have declared Timer component
When I put my component on a form how can I put the Timer to True with a MainMenu-item?

constructor TMyDrawingPanel.Create(AOwner: TComponent);
begin
  inherited Create (AOwner);
  CursorFlashTimer := TTimer.Create(self);          <----------------------------
  with  CursorFlashTimer do
  begin
    Enabled := False;
    Interval := 200;
    OnTimer := CursorFlashTimer_OnTImer;
  end;
  SCRCOLS := 80;
  SCRROWS := 24;
  SocOpen := False;
  ColorRed := clRed;

I have this, but this is not working:

procedure TConnectHost.miFlashCursorClick(Sender: TObject);
begin
  miFlashCursor.Checked := not miFlashCursor.Checked;
  CursorFlashTimer.Enabled := True;
end;

How can i put the Timer to True?

If the Timer is public or published in your component, you can access it just like any other
property:

MyDrawingPanel.CursorFlashTimer.Enabled := True;

I have put it in the Private part:

type
  TMyDrawingPanel = class(TCustomPanel)
  private
    { Private declarations }
    CursorFlashTimer: TTImer;              <----------------------
    Bounding: Boolean;
    fcursorVisible: boolean;
    AnchorX, AnchorY,
    CurX, CurY: Integer;
    SCRROWS: integer;
    SCRCOLS: integer;
    FontWidthPix: integer;
