@Alex42 Have you tried this windows dbus port from freedesktop.org?
Never tried it. Might be better than that archived dbus code you found on google.

mchinand

Is there a reason why you want to use D-Bus on Windows?

Alex42

@mchinand I let you take a look at my question in another topic,here
https://forum.qt.io/topic/131878/how-to-use-signals-slots-to-make-inter-process-communication-in-qt

@idlefrog yes i tried it, but i don't found more explanation about to run dbus-daemon on windows

@Alex42 I strongly believe you'd have it done faster by setting up interprocess communication using TCP socket. But then again, it is Windows, so who knows.

mchinand

I agree with @artwaw. Check out the fortune example client and server.

@mchinand, As you see, the problem it's not in the TCP/IP ( local server / socket ,shared memory ,QProcess class, QT Network ) , the problem it's how to run d-bus daemon on the windows , ( or how to use Qt D-Bus under Windows )

This is outside of Qt. I suggest you also search on the Internet.

how to use Qt D-bus on windows ?

In your main.cpp, before any other Qt code, paste this:

int main(int argc, char *argv[])
{
#ifdef Q_OS_WINDOWS
    // This variable comes from dbus-env.bat
    qputenv("DBUS_SESSION_BUS_ADDRESS", "autolaunch:");
#endif

If you also have all the DBus files, DLLs etc. in the same directory as your .exe, it will work.
