A basic QML type. More… The QtObject type is a non-visual element which contains only the objectName property. It can be useful to create a QtObject if you need an extremely lightweight type to enclose a set of custom properties: It can also be useful for C++ integration, as it is just a plain QObject.

How do I register a QObject as a QML object type?

To register a QObject -derived class as an instantiable QML object type, call qmlRegisterType () to register the class as QML type into a particular type namespace. Clients can then import that namespace in order to use the type.

How do you declare an instantiable class in QML?

Registering an Instantiable Object Type Any QObject -derived C++ class can be registered as the definition of a QML object type. Once a class is registered with the QML type system, the class can be declared and instantiated like any other object type from QML code.

What are attached properties in QML?

Providing Attached Properties In the QML language syntax, there is a notion of attached properties and attached signal handlers, which are additional attributes that are attached to an object. Essentially, such attributes are implemented and provided by an attaching type, and these attributes may be attached to an object of another type.
