Answer 1

Make sure 'QTextCursor' is registered using qRegisterMetaType().

Did you try to use qRegisterMetaType function?

The official manual says:

The class is used as a helper to marshall types in QVariant and in queued signals and slots connections. It associates a type name to a type so that it can be created and destructed dynamically at run-time. Declare new types with Q_DECLARE_METATYPE() to make them available to QVariant and other template-based functions. Call qRegisterMetaType() to make type available to non-template based functions, such as the queued signal and slot connections.
