WebEngine Widgets Minimal Example#
Displays a web page using Qt WebEngine Widgets.
** WebEngine Widgets Minimal Example demonstrates how to use
QWebEngineView 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.
We first define a
commandLineUrlArgument function that returns the URL to open. This is either the first positional argument given on the command line, or
https://www.qt.io as a fallback.
main function we first set the
organizationName property. This affects the locations where Qt WebEngine stores persistent and cached data (see also
Next, we instantiate a
QApplication and a
QWebEngineView . The URL to load is taken from
commandLineUrlArgument and loaded by calling
setUrl . The view widget is given a reasonable default size, and shown. Finally,
exec() launches the main event loop.
The example requires a working internet connection to render the Qt Homepage. An optional system proxy should be picked up automatically. However, for proxies that require a username or password, you need to connect to
Qt WebEngine Widgets uses the Qt Quick Scene Graph to compose the page. Therefore, OpenGL support is required.
