problem with menu entries for mdi windows

[marcel]

Nut if you don't want a QAction for the menu entry, how will you know when the user clicks one of the entries?

You have QMenu::addAction(const QString&). You can use its result(the QAction) and connect to its triggered signal. That's when the user clicked your menu entry and you can activate the corresponding window.

You also have variations on that: addMenu(const QString&), etc

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));
     }
 }

indeed i missed the example. Though i looked at it, i only looked at the windows menu and couldn't find a windows submenu, hence i thought that wasn't the right example. Now i noticed that the windows are appended to the menu.

thx for your help
