Hi, here is a little DBus Gypsy example, I hope it helps. The correct methodes can be found with mdbus.

Re: [q, fsot] howto dbus
QDBusConnection GPSConnection = QDBusConnection::systemBus(); ... thanks, no w i at least got an idea how to preceed. nevertheless, for want of gypsy i tried to connect to a signal from kwalletd (kde pasword management daemon), which besides others offers the signal org.kde.kwalletd /modules/kwalletd org.kde.KWallet.walletOpened() doing QDBusInterface* KWalletdInterface = new QDBusInterface(org.kde.kwalletd, /modules/kwalletd, org.kde.KWallet, QDBusConnection::sessionBus()); connect(KWalletdInterface, SIGNAL(walletOpened()), this, SLOT(slotOne())); always gives Object::connect: No such signal org::kde::KWallet::walletOpened() searching around, i found your thread with exactly the same problem (and my rather less helpful comments ;-) -- but you never posted a solution to that ... http://kerneltrap.org/index.php?q=mailarchive/openmoko-community/2008/11/26/4238514/thread ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

For KWallet you could try: QDBusConnection WalletConnection = QDBusConnection::sessionBus(); KDE stuff sits on session bus (AFAIR), and FSO sits on system bus. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: [q, fsot] howto dbus
QDBusConnection WalletConnection = QDBusConnection::sessionBus(); thanks, but that's not the problem. i think i solved it (at least, i hope that's the correct way): QDBusConnection::sessionBus().connect(org.kde.kwalletd, /modules/kwalletd, org.kde.KWallet, walletDeleted, this, SLOT(slotFour())); ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

that's maybe rather ot, but since i need it to program _with_ qt _for_ the freerunner ... short'n'sweet: has anybody a clear and usable tutorial howto write dbus apps with qt, notably registering an app to dbus and recieve dbus signals/events? say, as a plausible scenario, i want to subscribe to dbus and receive information about incoming calls (the same stuff zhone receives) ar make a call -- how do i go about? the stuff i found so far is to complex and has to little hands-on examples to use already existing infrastructure -- i am rather the type that embarks from small examples upon larger quests, not from reading lengthy texts and code which creates complete apps inclusive gui and all. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Hi Arne, I tried some time ago to use FSO DBUS with QT-4.5, as i'm a new comer to qt, i've learned the basics with their online doc[1] and tutorials[2] and did googling a lot! Then i took a look at telepathy as a serious QT/DBUS real-life example. I tried to use their (telepathy) dbus proxy generator, but finally i gave up more by lack of time. The FSO XML specs has to be enhanced to ease the work of the generator... Anyway i will have to go back to this in few month as we will use FSO DBUS interface likely with QT in some incoming project within my company. If you find anything interesting about QT/DBUS/FSO, please share it! Have fun!
