[dbus-cplusplus-devel] Any beginner information on dbus-c++?

[Mark <ma...@gm...>]

Hey,

First: i posted this message on the normal dbus list as well before i
knew that this list was around. Sorry for that.

I'm currently trying to figure out how i can make a simple DBus
program with the c++ wrapper.
I have no previous dbus experience or anythiong dbus related.

using the c api from dbus is not an option for me.

What i try to do (just as a begin) is reading out just some message
from dbus (lets say the currently played song in Rhythmbox or just any
app that sends something to dbus).
i just can't find any examples of how to use the c++ wrapper and read
a dbus message...

I hope anyone can help me with this.

Thanx,
Mark

Hello Mark,

there're several examples beside the dbus-c++ source:

examples> ls
echo   glib  Makefile     Makefile.in  properties_get_set
ecore  hal   Makefile.am  properties

The "ecore" example isn't in the main repo. But you should start with
the "echo" example to understand its basic usage. If you got this
running and understood the basic usage maybe you could ask more
detailed questions. Feel free to ask if there're still questions...

regards
Andreas

Hi,

Those examples are exactly the issue. it's nowhere being made clear
how i can add my own function in there like Hello(bla bla) which is in
there. if i add a function i have to ad it to various other files but
i don't know which ones.. that's not being said in those files or
anything close to it. the documentation of the examples is just..
missing..

So i can't get anywhere with those examples.
I still prefer using that dbus-c++ lib but i'm thinking of just using
the c api since that does have decent documentation and more users
where i can ask for help.

There's a XML file beside e.g. the hello example. Maybe you should
start to learn more about the introspection format:

http://dbus-cplusplus.wiki.sourceforge.net/Introspection+Format

Try the simple case with one method/signal, play with parameters and
see what the generator creates as output. If you understood the
introspection format half of the work is done. You've to use the
generated header files in your application.

I really have to write a beginners guide in the wiki. If you've success
be welcome to write something.

Please help to change the situation! :)

Well.. i would like to help but since i have just a little more then 5
weeks to get this done i really have to use what is the fastest way
for me. in the case of the dbus-c++ api and the dbus c api it's
leaning towards c because i can just follow examples there. If i had 4
months or something to work this all out i would probably invest a lot
more time in the c++ api

for now it seems unlikely that i'm gonna use it.

Also about this school project that i do now. If this project is a
success for my school it might (i said might!) be possible that it's
gonna be a part of the Computer Science lessons which means that about
40 students a year will try this dbus stuff and also might end up in
deciding to use dbus-c++.. and if that is so "beginner friendly" as it
is now then it might scare them off and (like me) also use the dbus c
api...

So for the sake of this project please make it beginner friendly ^_^

Also something that i find strange is that a newly made function is
not automatically assigned to dbus.. surely there must be a way to get
around this and make the dbus-c++ api more user friendly.
