\title WebEngine StyleSheet Browser Example
\ingroup webengine-widgetexamples
\brief Demonstrates how to inject CSS into web pages using user scripts
\image stylesheetbrowser.png
\e {StyleSheet Browser} demonstrates how to use the \l{Qt WebEngine Widgets C++ Classes}
{Qt WebEngine C++ classes} to inject user stylesheets into web pages.
\include examples-run.qdocinc
\section1 Working With Stylesheets
We use JavaScript to create and append CSS elements to the documents.
After declaring the script source, QWebEnginePage::runJavaScript() can run it
immediately and apply newly created styles on the current content of the web view.
Encapsulating the script into a QWebEngineScript and adding it to the script collection
of QWebEnginePage makes its effect permanent.
\quotefromfile webenginewidgets/stylesheetbrowser/mainwindow.cpp
\skipto MainWindow::insertStyleSheet
\printuntil /^\}/
Removing stylesheets can be done similarly:
\quotefromfile webenginewidgets/stylesheetbrowser/mainwindow.cpp
\skipto MainWindow::removeStyleSheet
\printuntil /^\}/
