  //Strangely, it must be show_all(), and show() has no effect,

  //This may be a bug in how HildonWindow implements show_all,
  //or maybe it's impossible for us to use the show_all vfunc override from show_all_children().
  //More likely, there are implementation container widgets in HildonWindow that should always be shown by default,
  //or always shown when a toolbar is present.
  //Anyway, if that's the case then let's just document it as necessary.
  //See bug #875.
