  27 /** when this is defined, the code will use
  28  * QFileDialog::getOpenFileName and friends to create filedialogs.
  29  * Effects:
  30  * - the dialog does not use the quick directory buttons (Button
  31  *   parameters);
  32  * - with Qt/Mac or Qt/Win, the dialogs native to the environment are used.
  33  * - with Qt/Win and Qt <= 4.3.0, there was a number of bugs with our own
  34  *   file dialog (http://www.lyx.org/trac/ticket/3907).
  35  *
  36  * Therefore there is a tradeoff in enabling or disabling this (JMarc)
