Detailed Description

This class implements both QGuiApplication and GCF::QmlApplicationServices. The only function it offers is processArgumentsAndExec(). You must create an instance of this class if you are building a QML application in GCF and call the GCF::QmlApplicationServices::setQmlEngine() method to set a QML engine for your application. Shown below is a typical main() function in a QML application

#include <GCF3/QmlApplication>
#include <GCF3/QmlComponent>

int main(int argc, char **argv)
{
    GCF::QmlApplication a(argc, argv);

    QQuickView qmlView;

    // This part is very important. You must
    // set a QML engine with the application!
    a.setQmlEngine(qmlView.engine());

    ....
    ....
    ....

    return a.processArgumentsAndExec();
}

Note

This class is available only if GCF is compiled and linked against Qt 5.

Qml applications cannot use QtWidgets module
