 \subsection{XRC file format}\label{xrcfileformat}
 

-\subsubsection{Introduction to the XRC file format}\label{xrcfileformatintro}
-
-This note describes the file format used for storing XRC resources that are
-used by wxXmlResource class. It is probably only useful for those implementing
-dialog editors with XRC support, or for those writing XRC files by hand.
+Please see Technical Note 14 (docs/tech/tn0014.txt) in your wxWidgets
+distribution.

 
 

-If you only want to use the resources, you can choose from a number of editors,
-as listed in \helpref{XRC concepts}{xrcconcepts}.
+\subsection{C++ header file generation}\label{xrccppheader}

 
 

-The XRC format is based on XML 1.0 (please consult W3C's specification). There
-is no DTD available since it is not possible to fully describe the format with
-the limited expressive power of DTDs.
+Using the {\tt -e} switch together with {\tt -c}, a C++ header file is written
+containing class definitions for the GUI windows defined in the XRC file.
+This code generation can make it easier to use XRC and automate program
+development.
+The classes can be used as basis for development, freeing the
+programmer from dealing with most of the XRC specifities (e.g. {\tt XRCCTRL}).

 
 

-\subsubsection{XRC terminology}\label{xrcterminology}
+For each top level window defined in the XRC file a C++ class definition is
+generated, containing as class members the named widgets of the window.
+A default constructor for each class is also generated. Inside the constructor 
+all XRC loading is done and all class members representing widgets are initialized. 

 
 

-The usual XML terminology applies. In particular, we shall use the terms 
-{\it node}, {\it property} and {\it value} in the XML sense:
+A simple example will help understand how the scheme works. Suppose you have
+a XRC file defining a top level window {\tt TestWnd\_Base}, which subclasses {\tt wxFrame} (any 
+other class like {\tt wxDialog} will do also), and has subwidgets {\tt wxTextCtrl} A and {\tt wxButton} B.
+The XRC file and corresponding class definition in the header file will be something like:

 
 \begin{verbatim}
 
 \begin{verbatim}

-    <node property1="value1" property2="value2">...</node>
-\end{verbatim}
-
-The term "attribute" is specific to XRC and refers to a property-less subnode 
-of an <object> or <object_ref> node. In the example bellow, <pos>, <label> and
-<style> are attributes, while neither <resource> nor either of <object>s is:
-
-\begin{verbatim}
-    <?xml version="1.0" encoding="utf-8">
-    <resource version="2.3.0.1">

-            <object class="wxStaticText">
-                <label>A label</label>
-                <pos>10,10</pos>
+<?xml version="1.0"?>
+<resource version="2.3.0.1">
+    <object class="wxFrame" name="TestWnd_Base">
+        <size>-1,-1</size>

-\subsubsection{XRC format high-level description}
-
-An XRC resource file is a well-formed XML 1.0 document. 
-
-The root node of XRC document must be <resource>. The <resource> node has 
-optional {\it version} property. Default version  (in absence of the version 
-property) is "0.0.0.0". The version consists of four integers separated by 
-periods. Version of XRC format changes only if there was an incompatible 
-change introduced (i.e. either the library cannot understand old resource 
-files or older versions of the library wouldn't understand the new format).
-The first three integers are major, minor and release number of the wxWindows 
-release when the change was introduced, the last one is revision number and 
-is 0 for the first incompatible change in given wxWindows release, 1 for 
-the second, and so on.
+    </object>
+</resource>

 
 

-Differences between versions are described within this document in paragraphs
-entitled {\it Version Note}.

 
 

-The <resource> node is only allowed to have <object> and <object_ref>
-subnodes, all of which must have the "name" property.
