    Default Running GThread and handling the Qt's event at the GCallBack.

    Hello Masters of Qt,

    After struglling lot with the problem,i have finally thought to put the question on thsi forum.

    I am developing a project which runs two applications,and both communicates using dbus. Client application is a main application and running in while(1).This uses Glib and libdbus.Inside while(1) it polls many other functions including Qt's GUI's Event queue.This application also runs GMainLoop inside a GThred,which is needed to tackle the Qt's signal directly with the Slots inside Main application.

    On,server side Qt is running. And performs GUI operations guided by main application . Communicates with the main using dbus and GLib.

    Now,when i run the whole software ,main applications runs only in while(1),and is able to poll the event-queue,but Qt's event is not able to invoke the GCallBack on client side.I think it gets stucked into a while(1),not able to poll other events.

    The same thing runs on PC,very well.But,when i try to run on ARM board,it is not able to h andle the GUI's events. can some one pls be able to guide me?

    Thanks to all developers.

    hello,

    can someonr please guide me on this problem pleaese?

    what can stops dbus from forwarding the Qt's signal to Glib's GCallBack(this is slot in qt's sense).

    i need to run g_main_loop_run() on Glib application,to get the signal. The Qt's signal is already connected with the Glibs GCallBack.
