# Qt WebEngine QML Types

To link against the module using build with qmake, add the following QT variable to your qmake .pro file:

     QT += webenginequick

For build with CMake use the `find_package()` command to locate the needed module components in the Qt6 package and `target_link_libraries()` to link against the module:

     find_package(Qt6 REQUIRED COMPONENTS WebEngineQuick)
     target_link_libraries(target PRIVATE Qt6::WebEngineQuick)

The minimal amount of code needed to load and display an HTML page using the QML engine requires a proper initialization:

     #include <QGuiApplication>
     #include <QQmlApplicationEngine>
     #include <QtWebEngineQuick/qtwebenginequickglobal.h>

     int main(int argc, char *argv[])
     {
         QCoreApplication::setAttribute(Qt::AA_ShareOpenGLContexts);
         QtWebEngineQuick::initialize();
         QGuiApplication app(argc, argv);
         QQmlApplicationEngine engine;
         engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
         return app.exec();
     }

Where the content of main.qml is simply:

     import QtQuick
     import QtQuick.Window
     import QtWebEngine

     Window {
         width: 1024
         height: 750
         visible: true
         WebEngineView {
             anchors.fill: parent
             url: "https://www.qt.io"
         }
     }
