title: How to change hint text while hint is shown in TBalloonHint?
body: <p>Before I used THint, and it was working with this code:</p>
  
  <pre><code>procedure TMainForm.FormCreate(Sender: TObject);
  begin
    Application.OnShowHint := AppShowHint;
  end;
  
  procedure TMainForm.AppShowHint(var HintStr: String; var CanShow: Boolean; var HintInfo: Controls.THintInfo);
  begin
    HintInfo.ReshowTimeout := 1;
  end;
  </code></pre>
  
  <p>Now I use TBalloonHint and want to change hint text when hint is shown. The above procedure is not triggered.</p>
  
  <p>I am changing the hint text each second, so when user enters control, the hint is shown and I want to update the hint text each second, also when user is not moving with the mouse.</p>
  
  <p>How to achieve this with TBalloonHint?</p>
