problem with menu entries for mdi windows

[spud]

You must have missed the MDI example.

// during construction:
     connect(windowMenu, SIGNAL(aboutToShow()), this, SLOT(updateWindowMenu()));
 
void MainWindow::updateWindowMenu()
 {
     windowMenu->clear();
     windowMenu->addAction(closeAct);
     windowMenu->addAction(closeAllAct);
     windowMenu->addSeparator();
     windowMenu->addAction(tileAct);
     windowMenu->addAction(cascadeAct);
     windowMenu->addSeparator();
     windowMenu->addAction(nextAct);
     windowMenu->addAction(previousAct);
     windowMenu->addAction(separatorAct);
 
     QList<QMdiSubWindow *> windows = mdiArea->subWindowList();
     separatorAct->setVisible(!windows.isEmpty());
 
     for (int i = 0; i < windows.size(); ++i) {
         MdiChild *child = qobject_cast<MdiChild *>(windows.at(i)->widget());
 
         QString text;
         if (i < 9) {
             text = tr("&%1 %2").arg(i + 1)
                                .arg(child->userFriendlyCurrentFile());
         } else {
             text = tr("%1 %2").arg(i + 1)
                               .arg(child->userFriendlyCurrentFile());
         }
         QAction *action  = windowMenu->addAction(text);
         action->setCheckable(true);
         action ->setChecked(child == activeMdiChild());
         connect(action, SIGNAL(triggered()), windowMapper, SLOT(map()));
         windowMapper->setMapping(action, windows.at(i));
     }
 }
