It shows the minimum amount of code needed to load and display an HTML page, and can be used as a basis for further experimentation. \include examples-run.qdocinc \section1 C++ Code In \c main.cpp we use only the QGuiApplication and QQmlApplicationEngine classes. We also include \c qtwebengineglobal.h to be able to use \l{QtWebEngine::initialize}. \quotefromfile webengine/minimal/main.cpp \skipto #include \printto main In the \c main function we first set the Qt::AA_EnableHighDpiScaling attribute. This lets the web view automatically scale on high-dpi displays. Then we instantiate a QGuiApplication object. Next, we call \l{QtWebEngine::initialize}, which makes sure that OpenGL contexts can be shared between the main process and the dedicated renderer process (\c QtWebEngineProcess). This method needs to be called before any OpenGL context is created. Then we create a QQmlApplicationEngine, and tell it to load \c main.qml from the \l{The Qt Resource System}{Qt Resource System}. Finally, QGuiApplication::exec() launches the main event loop. \printuntil } \section1 QML Code In \c main.qml we create the top level window, set a sensible default size and make it visible. The window will be filled by a WebEngineView item loading the \l{Qt Homepage}. \quotefromfile webengine/minimal/main.qml \skipto import \printuntil } \printline } \section1 Requirements The example requires a working internet connection to render the \l{Qt Homepage}. An optional system proxy should be picked up automatically. */
