registering a new QML type

To register a new QML type in C++, you can follow the steps below:

Step 1: Define the QML type - Create a new C++ class that inherits from QObject. - Add the Q_OBJECT macro at the beginning of the class declaration. - Define the properties, signals, and slots for the QML type using the Q_PROPERTY, Q_SIGNAL, and Q_SLOT macros.

Step 2: Register the QML type - In the main C++ file of your application, include the necessary headers for your QML type. - Use the qmlRegisterType function to register your QML type. This function takes the type name, version number, and URI as arguments. The URI is used to import your QML type in QML files.

Step 3: Import the QML type in QML - In your QML file, import the module that contains your QML type using the URI specified during registration. - You can now use your custom QML type as a regular QML component in your QML code.

That's it! Following these steps will allow you to register and use your custom QML type in your C++ application.
