Re: Launching Popup Windows in Gnoga

[David Botton <david@botton.com>]

I have pushed in to git changes to tutorial 6 that show how to more gracefully handle waiting for a popup.

It is not really possible to set an event on the popup since doing so would end up in a race condition in most situations. Also there is no "standard" between browsers to handle it properly.

In a multi_connect app if the popup is also a gnoga window it would be trivial to just have the two sync up in pure Ada using tasks or POs.

For the Singleton the following insures that you can both access the contents and also that the window has been created and displayed by the browser:

      while
        App.My_Popup2.Document.Ready_State /= Gnoga.Gui.Document.Complete or
        App.My_Popup2.Width = 0
      loop
         delay 0.25;
      end loop;

Also you will notice in Tutorial 6 that Launch now throws an exception if popups are blocked Gnoga.Gui.Window.Popup_Blocked
