#includeIn this example, we create a QObject called obj and set two dynamic properties: “name” with a value of “John” and “age” with a value of 35. We then retrieve the values of these properties using the property() method and store them in variables. The Qt library provides several packages, including QtCore, QtGui, QtWidgets, and QtNetwork. The example above uses the QtCore package.int main() { QObject obj; obj.setProperty("name", "John"); obj.setProperty("age", 35); QString name = obj.property("name").toString(); int age = obj.property("age").toInt(); return 0; }
