\title WebEngine Qt Quick Minimal Example
\ingroup webengine-examples
\brief Displays a web page using the Qt Quick integration of \QWE.
\image minimal-example.png
\e {WebEngine Qt Quick Minimal Example} demonstrates how to use the
\l{WebEngineView} item to render a web page. 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{QtWebEngineQuick::initialize}.
\quotefromfile webenginequick/minimal/main.cpp
\skipto #include
\printto main
In the \c main function we first set the
\l{QCoreApplication::organizationName} property. This affects the locations
where \QWE stores persistent and cached data (see also
\l{WebEngineProfile::cachePath} and
\l{WebEngineProfile::persistentStoragePath}).
Next, we call \l{QtWebEngineQuick::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 webenginequick/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.
