Preoblem with setQuitOnLastWindowClosed (false); and QMainWindow

[ivi2501]

Hi for all.
Now I develop sytem "Task Manager system " based on website + xmlrpc + windows software.

------------------------------------
Some months ago I develop simple software:

QApplication a(argc, argv);
a.setQuitOnLastWindowClosed ( false);

Main window based on QWidget

But now I use QMainWindow.


QApplication a(argc, argv);
a.setQuitOnLastWindowClosed (false);
mainWindow = new Gefest(config);
mainWindow->show();

When I click close on MainWindow window not closed but hide to systemtray.
When I close subwindow software closed.
Please help.
setQuitOnLastWindowClosed not work with QMainWindow?

It works fine for me. You must be doing something wrong. Maybe the application crashes and not closes itself gracefully?

task.init(config);




// QObject::connect(mainWindow, SIGNAL(changeTaskType(QString&) ), &task, SLOT(changeTaskType(QString&) ));

//########## INIT GLOBAL

a.connect(&a, SIGNAL(lastWindowClosed()), &a, SLOT(quit()));
return a.exec();
}
