How to open an URL in a regular browser instead of opening it in a TWebBrowser (Views: 100)


Problem/Question/Abstract:

I have a TWebBrowser in my application that loads unknown remote content. When a user clicks on any link in it, I would like to have the URL opened in a regular browser, but not within the TWebBrowser itself. I do not want the TWebBrowser to act upon the click.

Answer:

Use the OnBeforeNavigate2 event like that:

procedure TForm1.WebBrowser1BeforeNavigate2(Sender: TObject; const pDisp: IDispatch;
  var URL, Flags, TargetFrameName, PostData, Headers: OleVariant; var Cancel: WordBool);
begin
  if not FManuallyLoading then
  begin
    {Stop Loading in this Browser ...}
    Cancel := True;
    {... but open in new Browser}
    Flags := Flags or 1;
    (Sender as TWebBrowser).Navigate(WideString(URL), Flags,
      TargetFrameName, PostData, Headers);
  end;
end;


Set FManuallyLoading to True, while you are programmatically loading content into the web browser:


procedure TForm1.Button1Click(Sender: TObject);
begin
  FManuallyLoading := True;
  WebBrowser1.Navigate('http://www.nineberry.de');
  FManuallyLoading := False;
end;
