For KDE 4, the old DCOP has been replaced with D-Bus. Konsole does support numerous methods that can be used with D-Bus.
There are two ways to use the D-Bus interface: Qt™'s GUI qdbusviewer and the command line qdbus.
Examples:
%
qdbus
will display all services available.
%
qdbus
org.kde.konsole
will display the D-Bus interface for Konsole.
%
qdbus
org.kde.konsole /Konsole
will display methods for controlling the main Konsole window.
%
qdbus
org.kde.konsole /Sessions/1
will display methods for session 1.
If you start Konsole from a terminal you may need to change
org.kde.konsole to
org.kde.konsole-`pidof -s konsole`.
