That is nice in theory, and i would gladly do that, if it was of some use. 
However, konsole is using TEPty class, which is derived from KProcess. So, 
without a delegation-based object model, which C++ has not, i can't make any 
real use of such a subclass, especially not from a client application. And 
TEPty is private to konsole, it is not exposed in any of the APIs.

Anyway, thanks for the comment. I will go with binary wrapper and some hacks, 
until i manage to fix the api in some way. But i believe this is unneccessary 
ugliness, and really should be fixed in the API. Any suggestions on solving 
this in an elegant way (i'm thinking about using functor to call back into 
user code, for example; but it's essentially the same as signal, just without 
its (not really wanted) multiple dispatch) would be appreciated.
