Update of /cvs/dbus/dbus/qt/tools
In directory kemper:/tmp/cvs-serv5955/qt/tools
Added Files:
.cvsignore Makefile.am dbuscpp2xml.cpp dbusidl2cpp.cpp
Log Message:
* qt/: Update to Subversion r548032.
This includes a big reorganisation of the files inside the
subdir.
We really need a version control system that supports moving of
files. I'm not bothering with history anyways anymore, since the
bindings will be moved out to git. The history should be restored from
Subversion when that happens.

\title QtDBus IDL compiler (dbusidl2cpp)
The QtDBus IDL compiler is a tool that can be used to parse interface descriptions and produce
static code representing those interfaces, which can then be used to make calls to remote
objects or implement said interfaces.
\c dbusidl2dcpp has two modes of operation, that correspond to the two possible outputs it can
produce: the interface (proxy) class or the adaptor class.The latter consists of both a C++
header and a source file, which are meant to be edited and adapted to your needs.
The \c dbusidl2dcpp tool is not meant to be run every time you compile your
application. Instead, it's meant to be used when developing the code or when the interface
changes.
The adaptor classes generated by \c dbusidl2cpp are just a skeleton that must be completed. It
generates, by default, calls to slots with the same name on the object the adaptor is attached
to. However, you may modify those slots or the property accessor functions to suit your needs.
