XRCed is a resource editor for editing XRC resource files used in wxWidgets or wxPython. XRC is an XML-based format for describing the layout of the interface. When a XRC file it being parsed in the application (using wxXmlResource class), objects corresponding to the interface elements defined in .xrc file are created and can be immediately used. Please refer to the corresponding documentation depending on your language for details. XRC files are actually normal text files. Structure of an XML file is defined by a hierarchy of nodes, each node is delimited by a pair of tags in a similar manner to HTML format. XRC format uses a special object tag for defining interface element nodes, which can contain a number of attribute nodes with tag names corresponding to the attribute names, e.g. <pos>100,100</pos>. Object nodes always have XML attribute "class'' defined, e.g. <object class='wxFrame'>.
