CVersionNumber	Extends QVersionNumber to include a dedicated constructor and getter for the fourth version segment
CWinGuiEvent	Encapsulates messages that are sent directly to an application window by the system on the Windows platform
CXmlStreamReaderError	Full error object for QXmlStreamReader, similar to other Qt classes, that can be more convenient for processing errors than just QXmlStreamReader::Error
CXmlStreamWriterError	Full error object for QXmlStreamWriterError, similar to other Qt classes. QXmlStreamWriter doesn't have an intrinsic error type, but this class can be useful for passing contextual error information when writing XML data so that intent is more clear
▼NQxErrorPrivate
Cadapter_registry
▼NQxJson	The `QxJson` namespace encapsulates the user-extensible implementation of Qx's JSON parsing facilities
