@ Bibek:
Actually i dont understand how the url will be passed to my application when a feeditem is clicked. Like it will come through arguments in main() method or it will be automatically passed to openUrl method of my application when i define
QDesktopServices::setUrlHandler() in my main method.

@qwazix:
I am doing the same approach to generate feeds on home screen, but the problem is that DBus service crashes when i close UI that is generated in response when a feeditem is clicked.

@Copernicus:
Yes two main methods main two applications, one for DBus service and one as daemon. Initially my approach was to have one application doing all the stuff (DBus, GUI) but quitting GUI quits the application thereby crashing the DBus service.
