///     @brief Subclass of QMessageBox which re-implements the static public functions. There are two reasons for this:
///             1) The QMessageBox implementation on OSX does now show the title string. This leads to message
///             boxes which don't make much sense. So on OSX we set title to text and text to informative text.
///             2) If parent is NULL, we set parent to MainWindow::instance
