XRC, or XML Resource, or XML Based Resource System is a cross-platform XML-based user interface markup language used by wxWidgets. XRC allows graphical user interface elements, such as dialogs, menu bars and toolbars, to be stored as XML, which can be loaded into the application at run-time or translated into a target programming language and compiled. Advantages Recompiling and linking is not always necessary when changing the interface. Separates the interface from the program logic. Ability to choose between different resource files at run time. XRC is a wxWidgets standard, so it can be generated and processed by any program that understands it. They can be written (or generated by other program) once, and used in any supported language which have wxWidgets bindings. XML is easier to parse than most programming languages. Existing XML editors can be used to edit XRC files. Tools Specialized software tools, generally graphical user interface builder or rapid application development (RAD), allow creation of XRC files, among them are: wxFormBuilder XRCed wxDesigner DialogBlocks wxSmith (Code::Blocks plugin) See also wxWidgets wxGlade - an open source GUI designer that understands and generates XRC List of user interface markup languages XUL QML References External links XML Based Resource System overview (current) XML-based resource system overview (stable) XRCed - an XRC editor XRC Tutorial XML-based standards User interface markup languages WxWidgets
