The XML-based resource system, known as XRC, allows user interface elements such as
dialogs, menu bars and toolbars, to be stored in text files and loaded into
the application at run-time. XRC files can also be compiled into binary XRS files or C++
-code (the former makes it possible to store all resources in since file and the latter
+code (the former makes it possible to store all resources in a single file and the latter
is useful when you want to embed the resources into the executable).
There are several advantages to using XRC resources.
\begin{itemize}\itemsep=0pt
\item Recompiling and linking an application is not necessary if the
resources change.
-\item If you use a dialog designers that generates C++ code, it can be hard
+\item If you use a dialog designer that generates C++ code, it can be hard
to reintegrate this into existing C++ code. Separation of resources and code
is a more elegant solution.
\item You can choose between different alternative resource files at run time, if necessary.
\item call {\tt wxXmlResource::Get()->InitAllHandlers()} from your wxApp::OnInit function,
and then call {\tt wxXmlResource::Get()->Load("myfile.xrc")} to load the resource file;
\item to create a dialog from a resource, create it using the default constructor, and then
-load using for example {\tt wxXmlResource::Get()->LoadDialog(\&dlg, this, "dlg1");}
+load it using for example {\tt wxXmlResource::Get()->LoadDialog(\&dlg, this, "dlg1");}
\item set up event tables as usual but use the {\tt XRCID(str)} macro to translate from XRC string names
to a suitable integer identifier, for example {\tt EVT\_MENU(XRCID("quit"), MyFrame::OnQuit)}.
\end{itemize}
\item use \urlref{XRCed}{http://xrced.sf.net}, a wxPython-based
dialog editor that you can find in the {\tt wxPython/tools} subdirectory of the wxWidgets
CVS archive;

It is highly recommended that you use a resource editing tool, since it's fiddly writing
XRC files by hand.
\item -e (--extra-cpp-code): if used together with -c, generates C++ header file
containing class definitions for the windows defined by the XRC file (see special subsection)
\item -u (--uncompressed): do not compress XML files (C++ only)
-\item -g (--gettext): output .po catalog (to stdout, or a file if -o is used)
+\item -g (--gettext): output underscore-wrapped strings that poEdit or gettext can scan. Outputs to stdout, or a file if -o is used
\item -n (--function) <name>: specify C++ function name (use with -c)
\item -o (--output) <filename>: specify the output file, such as resource.xrs or resource.cpp
\item -l (--list-of-handlers) <filename>: output a list of necessary handlers to this file

it with standard ZIP tools. Note that if you are using XRS files, you have

exe file). XRC provides means to convert resources into regular C++ file that
can be compiled and included in the executable.
The generated window class can be used as basis for the full window class. The
class members which represent widgets may be accessed by name instead of using
{\tt XRCCTRL} every time you wish to reference them (note that they are {\tt protected} class members),
