+/**
+ * TerminalInterface is an interface implemented by KonsolePart to
+ * allow developers access to the KonsolePart in ways that are not
+ * possible through the normal KPart interface.
+ *
+ * Note that besides the functions below here, KonsolePart also has
+ * some signals you can connect to. They aren't in this class cause
+ * we can't have signals without having a QObject, which
+ * TerminalInterface is not.
+ * These are the signals you can connect to:
+ * void processExited( KProcess *process );
+ * void receivedData( const QString& s );
+ * See the example code below for how to connect to these..
+ *
+ * The process provided by processExited() is obviously exited,
+ * and is only guaranteed to be valid until you return from the
+ * slot connected to it!
+ *
+ * Use it like this:
+ * \code
+ * // fetch the Library..
+ * KLibFactory* factory = KLibLoader::self()->factory( "libkonsolepart" );
+ * if ( factory == 0L )
+ * {
+ * // inform the user that he should install konsole..
+ * return;
+ * };
+ * // fetch the part..
+ * KParts::Part* p = static_cast<KParts::Part*>(
+ * factory->create( this, "tralala", "QObject",
+ * "KParts::ReadOnlyPart" ) );
+ * assert( p );
+ * setCentralWidget( p->widget() );
+ *
+ * // cast the part to the TerminalInterface..
+ * TerminalInterface* t = static_cast<TerminalInterface*>( p->qt_cast( "TerminalInterface" ) );
+ * if( ! t )
+ * {
+ * // This probably happens because the konsole that is installed
+ * // comes from before KDE 3.2 , and the TerminalInterface is not
+ * // available.. What you can do here is either inform the user
+ * // that he needs a more recent konsole, or try to deliver the
+ * // functionality in some other way...
+ * return;
+ * };
+ * // now use the interface in all sorts of ways, e.g.
+ * // t->showShellInDir( QDir::home().path() );
+ * // or:
+ * // QStrList l;
+ * // l.append( "python" );
+ * // t->startProgram( QString::fromUtf8( "/usr/bin/python" ), l);
+ * // or connect to one of the signals. Connect to the Part object,
+ * // not to the TerminalInterface, since the latter is no QObject,
+ * // and as such cannot have signals..:
+ * // connect( p, SIGNAL( processExited( int ) ),
+ * // this, SLOT( shellExited( int ) ) );
+ * // etc.
+ *
+ * \endcode
+ *
+ * @since 3.2
