    This is not possible.
    Adding a virtual method is not a binary compatible change (virtual method table changes size) and thus not allowed in public API by KDE's library policies

    That doesn't look right.
    Calling isConfiguring() should IMHO not change the state.
    
    isXXX() usually only check a state without affecting it

My opinion on this matter is that this shouldn't be possible, so I modified slightly AgentBase to add the isConfiguring() method which is designed to only be called from within the configure() function of an agent. I did it this way so as to minimize the burden on agent implementors.
