[Interest] QOpenGLWindow inside QSplitter horizontal layout ?

[Nicholas Yue]

Hi,

I am learning about QOpenGLWindow

I saw examples which utilizes it via

        QWidget::createWindowContainer()

I am wondering if there is a way to house it as a widget inside a layout ?

My current attempt is not working.

```
MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow),
    m_myWindow(new MyOpenGLWindow)
{
    ui->setupUi(this);

    connect(ui->actionQuit, &QAction::triggered, this,
&MainWindow::OnFileClose);

    m_myWindow->create();
#ifdef ORIGINAL_WORKING_EXAMPLE
    m_myWindow->setMainWindow(this);
    QWidget *w = QWidget::createWindowContainer(m_myWindow);

    takeCentralWidget();
    setCentralWidget(w);
#else
    m_myWindow->setMainWindow(this);
    QWidget *w = QWidget::createWindowContainer(m_myWindow);
    // delete ui->targetWidget;
    // ui->targetWidget = QWidget::createWindowContainer(m_myWindow);
    // ui->targetWidget->setMinimumSize(400,400);
    w->setMinimumSize(200,200);
    w->setMaximumSize(200,200);
    // ui->targetWidget->createWindowContainer(m_myWindow);
    // takeCentralWidget();
    //setCentralWidget(ui->targetWidget);
    ui->splitter->layout()->addWidget(w);
#endif
}
```

Cheers
