int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QMainWindow *mainWindow = new QMainWindow;
    QMainWindow *subWindow = new QMainWindow(mainWindow);

In general, yes, but why do you think you need it?
QMainWindow is just a QWidget class with some status bars and menus after all...
In most cases where people think they need two QMainWindows , a normal QWidget or any other design is better/fine.

Never seen a use case for that. And it’s risky business, especially when floating dock widgets come into play.

@thomasGl Sure, use MDI windows.
