#register_to_qml(opts = {}) ⇒ Object

Registers the class as a QML type.

Parameters:

  • opts (Hash) (defaults to: {})

Options Hash (opts):

  • :under (String) —

    the namespece which encapsulates the exported QML type. If not specified, automatically inferred from the module nesting of the class.

  • :version (String) —

    the version of the type. Defaults to VERSION constant of the encapsulating module / class of the class.

  • :name (String) —

    the name of the type. Defaults to the name of the class.
