-    be sent or posted using sendEvent(), postEvent(), and
-    sendPostedEvents(). Pending events can be removed with
-    removePostedEvents() or flushed with flush(). Library paths (see
-    QLibrary) can be retrieved with libraryPaths() and manipulated by
-    setLibraryPaths(), addLibraryPath(), and removeLibraryPath().
