It sounded good. Here's what else didn't work ;)

void QtActionProxy::mwstatusbar(const QString& action, int param)
{
  //QWidget* mainWindow = QWidget::topLevelWidget();
  //QStatusbar *sb = mainWindow->findChildren<QStatusbar>();
//  QStatusBar *sb = 
dynamic_cast<QStatusBar*>(mainWindow->find<QStatusBar>());
  //QStatusBar* statbar= QMainWindow::statusBar() const;
//  QStatusBar* statbar = 
dynamic_cast<QStatusBar*>(mainWindow->child(statusBar(), "QStatusBar"));
  //QWidget* sb = mainWindow.find ( "automatic status bar" )->message( action, 
param );
  //QObject* sb = mainWindow.child("automatic status bar", QStatusBar, TRUE);
  QObject* mainWindow = QWidget::topLevelWidget();
  QObject* sb mainWindow::child ( "automatic status bar");
  sb->message( action, param );
}
