Let be more precise here - in your first if method you do something for kde4
or kde5 not tde. In kde3 and later in tde dcop is the message
buss/interface between different applications. DBus emerged later and won
the public, so kde4 and kde5 also gnome and most of the modern systems use
it.
I think the best way is to examine what interfaces are provided by which
application in dcop. Maybe kdcop will help you.
