How Can I get Qt version, for example 5.11.2 or similar, in my QML code. In my C++ code I have these options:



Method available on C++:



qVersion();


Macro available on C++:



QT_VERSION


But I couldn't find anything on QML?

          You could use a Context Property, as explained here.



          A simple example, given a simple qml file like this:



          import QtQuick 2.9
          import QtQuick.Window 2.2

          Window {

          Text {
          text: qtversion
          }

          visible: true
          width: 640
          height: 480
          title: qsTr("Hello World")
          }


          Set the qtversion property at startup, in main function:



          #include <QGuiApplication>
          #include <QQmlApplicationEngine>
          #include <QQmlContext>

          int main(int argc, char *argv)
          {
          QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);

          QGuiApplication app(argc, argv);

          QQmlApplicationEngine engine;
          engine.rootContext()->setContextProperty("qtversion", QString(qVersion()));
          engine.load(QUrl(QStringLiteral("qrc:/main.qml")));
          if (engine.rootObjects().isEmpty())
          return -1;

          return app.exec();
          }
