Update of /cvs/dbus/dbus/qt/examples
In directory kemper:/tmp/cvs-serv25972/qt/examples
Added Files:
.cvsignore Makefile.am chat.cpp chat.h chatadaptor.cpp
chatadaptor.h chatmainwindow.ui chatsetnickname.ui
com.trolltech.ChatInterface.xml complexping.cpp complexping.h
complexpong.cpp complexpong.h dbus.cpp hello.cpp ping-common.h
ping.cpp pong.cpp pong.h
Log Message:
* configure.in qt/Makefile.am: add qt/examples
* qt/examples: Add QtDBus example programs:
- hello: Hello, World
- ping: Simple method-calling program
- pong: Simple object-exporting program (not using adaptors)
- complexping: Interactive method-calling program
(also gets and sets properties).
- complexpong: Sample program exporting methods, signals and
properties, using adaptors.
- dbus: Simple implementation of a generic method-calling
program, similar to 'dbus-send', but with semantics
similar to 'dcop'.
- chat: Simplistic chat program, implemented using signals
and the system bus. Looks like IRC.
