WebEngine Qt Quick Minimal Example#

Displays a web page using the Qt Quick integration of Qt WebEngine.

** WebEngine Qt Quick Minimal Example demonstrates how to use the 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.

Running the Example#

To run the example from Qt Creator , open the Welcome mode and select the example from Examples. For more information, visit Building and Running an Example.

C++ Code#

In main.cpp we use only the QGuiApplication and QQmlApplicationEngine classes. We also include qtwebengineglobal.h to be able to use initialize .

In the main function we first set the organizationName property. This affects the locations where Qt WebEngine stores persistent and cached data (see also WebEngineProfile::cachePath and WebEngineProfile::persistentStoragePath ).

Next, we call initialize , which makes sure that OpenGL contexts can be shared between the main process and the dedicated renderer process (QtWebEngineProcess). This method needs to be called before any OpenGL context is created.

Then we create a QQmlApplicationEngine , and tell it to load main.qml from the Qt Resource System .

Finally, exec() launches the main event loop.

QML Code#

In 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 Qt Homepage.

Requirements#

The example requires a working internet connection to render the Qt Homepage. An optional system proxy should be picked up automatically.
