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