CList	Collection of static functions pertaining to lists
CLoginDialog	Modal dialog that prompts a user for a username and password
CNetworkReplyError	Full error object for QNetworkReply, similar to other Qt classes, that can be more convenient for processing errors than just QNetworkReply::NetworkError
CProcessBider	Monitors the presence of a process and signals when that process ends
CProcessBiderError	Describes errors than can occur during process biding
CProgressGroup	Distinct portion of overall progress to be mediated by GroupedProgressManager
CQJsonParseErrorAdapter	Allows QJsonParseError to be used via the Qx::Error interface
CRegularExpression	Collection of convenient regular expression statements
CSetOnce	The SetOnce template class acts as a container for a value that can only be set once
CShortcutProperties	The ShortcutProperties struct acts as a user-friendly container for holding IShellLink data, which are the varies properties of a Windows `.lnk` shortcut
CStandardItemModel	More robust variant of QStandardItemModel, which is a generic model for storing custom data
CString	Collection of static functions pertaining to string types
CStringLiteral	The StringLiteral template struct acts as a literal class type wrapper around a C-style string that effectively allows the string to be used as a non-type template parameter
CSyncDownloadManager	Used to queue and process one or more downloads in a synchronous manner
CSystemError	Encapsulates system generated errors as an Qx::Error interface compatible object
CTable	The Table class is a template class that provides a dynamic two-dimensional array
CTaskbarButton	Windows taskbar button for a top-level window
CTextPos	Used to represent an offset within a text file in terms of lines and characters
CTextQuery	Rules for conducting a search of text
CTextStream	More robust variant of QTextStream, which provides a convenient interface for reading and writing text
CTextStreamReader	Specialized wrapper for QTextStream that narrows and simplifies its usage for reading text files
CTextStreamWriter	Specialized wrapper for QTextStream that narrows and simplifies its usage for writing text files
CTraverser	The Traverser template class provides a const_iterator wrapper for an alternate approach to iterating over a type
CTreeInputDialog	Simple tree-based dialog from which the user can select one or more items
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
CArray	The array class represents a JSON array node for use in error contexts
