Just a QWidget:

class MainWin(QtGui.QTextEdit):
    def __init__(self, mapper, parent=None):
        QtGui.QTextEdit.__init__(self, parent)
        self.qsn = QtCore.QSocketNotifier(0, QtCore.QSocketNotifier.Read, self)
        self.connect(self.qsn, Qt.SIGNAL('activated(int)'), self.on_qsn)
        self.stdin = QtCore.QFile(self)
        self.stdin.open(0, QtCore.QIODevice.ReadOnly)
        self.connect(self.stdin, Qt.SIGNAL('readyRead()'), self.on_stdinReadyRead)
    def on_qsn(self, i):
    def on_stdinReadyRead(self):
        print "ready read!"
        line = self.stdin.readAll()
        print "got [%s]" % line

if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)

    win = MainWin(mapper)
