+  \ingroup advanced
+  \brief The TQIconFactory class is used to create pixmaps for a QIconSet.
+
+  By reimplementing createPixmap(), you can override QIconSet's
+  default algorithm for computing pixmaps not supplied by the user.
+
+  Call setAutoDelete(TRUE) if you want the factory to automatically
+  delete itself when it is no longer needed by QIconSet.
