Get error with QWebEngineView

[A Former User]

Hello,
i have this code:

#include <QString>
#include <QTimer>
#include <QThread>
#include <QTime>
#include <QMainWindow>
#include <QApplication>
#include <QWebEngineView>

int main(int argc, char *argv[])
{

  QApplication app(argc, argv);


 QMainWindow *mainWin = new QMainWindow;

 QWebEngineView *view = new QWebEngineView;
 view->load(QUrl("http://qt.io/"));
 view->show();
 mainWin->setCentralWidget(view);

   mainWin->showMaximized();
   return app.exec();
}

And in the output i'll get this:

Debuggen beginnt
[1205/181633:ERROR:scoped_ole_initializer.cc(20)] Multiple OleInitialize() calls for thread 8904

Hi! You need to take of the lifetime of your QObjects ;)

int main(int argc, char *argv[])
{

    QApplication app(argc, argv);
    QMainWindow mainWin;
    QWebEngineView *view = new QWebEngineView(&mainWin);
    view->load(QUrl("http://qt.io/"));
    view->show();
    mainWin.setCentralWidget(view);
    mainWin.showMaximized();
    return app.exec();
}

These messages aren't critical, you can ignore them. What's important is, that you don't crash the application anymore.
