When I start the application it should check if a specific program is
already started by the system or by other user - it doesn't matter. If this
program was started - do nothing, if the program is not started - the user
can decide to start it or not.
I read in the TQProcess documentation and some good articles, but I do not
see a trivial way. I think I'll have to try communication with the program
(dbus) and if the program answers it means it is running if not ... the
user can decide what to do. I think this is the only "proper" way from what
I understood. The thing is that it should be done by the program itself.
I was hoping KUniqueApplication would do the work, but obviously it doesn't
(I didn't have time to see why). So I think I'll stick to following
algorithm
Start
try dbus
if dbus instance exists, then exit
if dbus instance does not exist, start new instance.
