dbus/qt/dbusidl2cpp.cpp
Thiago Macieira 074b0b8674 2006-03-06 Thiago Macieira <thiago.macieira@trolltech.com> 
* qt/dbusidl2cpp.cpp:
	* qt/Makefile.am: add the dbusidl2cpp tool, the replacement
	for dcopidl2cpp, found in the KDE installations (or the more
	modern kalyptus): generate Qt4 C++ code for the input XML
	introspection. Currently no IDL parsing.

\page dbusidl2cpp 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.
\p %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 former is similar to the
\ref StandardInterfaces classes that are part of the QtDBus API and consists of a single .h file,
which should not be edited. The latter consists of both a C++ header and a source file, which
are meant to be edited and adapted to your needs.
The \p %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 \p %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.
