{\bf IMPORTANT NOTE:} XRC is not yet a part of the core wxWindows library, so
|
|
|
|
please see the next section for how to compile and link it. Otherwise if you
|
|
|
|
try to use it, you will get link errors.

|
|
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, so an XML parser does not need to be linked with the application and load times
|
|
|
|
are faster.
|
|
|
|
|
|
|
|
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
|
|
|
|
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 The XRC format uses sizers for flexibility, allowing dialogs to be resizable
|
|
|
|
and highly portable.
|
|
|
|
\item The XRC format is a wxWindows standard,
|
|
|
|
and can be generated or postprocessed by any program that understands it. As it is based
|
|
|
|
on the XML standard, existing XML editors can be used for simple editing purposes.
|
|
|
|
\end{itemize}
|
|
|
|
|
|
|
|
XRC was written by Vaclav Slavik.

|
|
\subsection{Compiling and using XRC}\label{compilingxrc}
|
|
|
|
|
|
|
|
XRC can be found under the 'contrib' hierarchy, in the following directories:
|
|
|
|
|
|
|
|
\begin{verbatim}
|
|
|
|
contrib/src/xrc ; XRC source
|
|
|
|
contrib/include/wx/xrc ; XRC headers
|
|
|
|
contrib/samples/xrc ; XRC sample
|
|
|
|
contrib/utils/wxrc ; XRC resource compiler
|
|
|
|
contrib/utils/wxrcedit ; XRC editor (in progress)
|
|
|
|
\end{verbatim}
|
|
|
|
|
|
|
|
To compile XRC:
|
|
|
|
|
|
|
|
\begin{itemize}\itemsep=0pt
|
|
|
|
\item Under Windows using VC++, open the contrib/src/xrc/XrcVC.dsw project
|
|
|
|
and compile. Also compile contrib/utils/wxrc using wxBase if you wish to compile
|
|
|
|
resource files.
|
|
|
|
\item Under Unix, XRC should be configured when you configured
|
|
|
|
wxWindows. Make XRC by changing directory to contrib/src/xrc and
|
|
|
|
type 'make'. Similarly compile contrib/utils/wxrc using wxBase if you wish to compile
|
|
|
|
resource files. {\bf Note:} there is currently a
|
|
|
|
problem with the wxWindows build system that means that
|
|
|
|
only the static version of library can be built at present.
|
|
|
|
\end{itemize}
|
|
|
|
|
|
|
|
To use XRC:
|
|
|
|
|
|
|
|
\begin{itemize}\itemsep=0pt
|
|
|
|
\item Under Windows using VC++, link with wxxrc[d].lib.
|
|
|
|
\item Under Unix, link with libwxxrc[d].a.
|
|
|
|
\end{itemize}
|
|
|
|
|
|
|
|
\subsection{XRC concepts}\label{xrcconcepts}
|
|
|
|
|
|
|
|
These are the typical steps for using XRC files in your application.
|
|
|
|
|
|
|
|
\begin{itemize}\itemsep=0pt
|
|
|
|
\item Include the appropriate headers: normally "wx/xrc/xmlres.h" will suffice;
|
2002-03-22 14:13:29 -05:00
|
|
|
\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;
|
2002-01-23 10:17:44 -05:00
|
|
|
\item to create a dialog from a resource, create it using the default constructor, and then
|
2002-05-05 10:24:07 -04:00
|
|
|
load using for example {\tt wxXmlResource::Get()->LoadDialog(\&dlg, this, "dlg1");}
|
2002-03-22 14:13:29 -05:00
|
|
|
\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)}.
|
2002-01-23 10:17:44 -05:00
|
|
|
\end{itemize}
|
|
|
|
|
|
|
|
To create an XRC file, use one of the following methods.
|
|
|
|
|
2002-05-05 10:24:07 -04:00
|
|
|
\begin{itemize}\itemsep=0pt
|
2002-01-23 10:17:44 -05:00
|
|
|
\item Create the file by hand;
|
2002-01-26 16:52:55 -05:00
|
|
|
\item use \urlref{wxDesigner}{http://www.roebling.de}, a commercial dialog designer/RAD tool;
|
|
|
|
\item use \urlref{XRCed}{http://www.mema.ucl.ac.be/~rolinsky/xrced/}, a wxPython-based
|
|
|
|
dialog editor that you can find in the {\tt wxPython/tools} subdirectory of the wxWindows
|
|
|
|
CVS archive;
|
|
|
|
\item use \urlref{wxWorkshop}{http://wxworkshop.sourceforge.net} (under development);
|
|
|
|
\item use wxrcedit ({\tt utils/contrib/wxrcedit}) (under development);
|
|
|
|
\item convert WIN32 RC files to XRC with the tool in {\tt contrib/utils/convertrc}.
|
2002-01-23 10:17:44 -05:00
|
|
|
\end{itemize}
|
|
|
|
|
|
|
|
It is highly recommended that you use a tool such as wxDesigner, since it's fiddly writing
|
|
|
|
XRC files by hand.
|
|
|
|
|
|
|
|
You can use \helpref{wxXmlResource::Load}{wxxmlresourceload} in a number of ways.
|
|
|
|
You can pass an XRC file (XML-based text resource file), an XMB file (compiled binary file)
|
|
|
|
or a zip-compressed file (extension ZIP or RSC) containing other XRC or XMB files.
|
|
|
|
|
|
|
|
TODO: is the compiled binary format XMB or XRS? How do you handle a C++ resource file?
|
|
|
|
|
|
|
|
\subsection{Using binary resource files}\label{binaryresourcefiles}
|
|
|
|
|
|
|
|
To compile binary resource files, use the command-line wxrc utility. It takes a single file parameter (the
|
|
|
|
input XRC file) and the following switches and options.
|
|
|
|
|
2002-05-05 10:24:07 -04:00
|
|
|
\begin{itemize}\itemsep=0pt
|
2002-01-23 10:17:44 -05:00
|
|
|
\item -h (--help): show a help message
|
|
|
|
\item -v (--verbose): show verbose logging information
|
|
|
|
\item -c (--cpp-code): write C++ source rather than a RSC file
|
|
|
|
\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 -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
|
|
|
|
\end{itemize}
|
|
|
|
|
|
|
|
For example:
|
|
|
|
|
|
|
|
\begin{verbatim}
|
|
|
|
% wxrc resource.wrc
|
|
|
|
% wxrc resource.wrc -o resource.wrs
|
|
|
|
% wxrc resource.wrc -v -c -o resource.cpp
|
|
|
|
\end{verbatim}
|
|
|
|
|
|
|
|
\subsection{XRC C++ sample}\label{xrccppsample}

|
|
|
|
This is the C++ source file (xrcdemo.cpp) for the XRC sample.
