    Question the usage of connect in QT

    Hello, Everyone:
    I read a code block in an open source program as follows:
    Qt Code:
    1. connect(getThread,SIGNAL(newObs(QByteArray, QList<t_satObs>)),
    2. this, SIGNAL(newObs(QByteArray, QList<t_satObs>)));
    To copy to clipboard, switch view to plain text mode 
    The problem is that two parameters of the connect function are both 'SIGNAL'.
    Can you give me some description of the usage ,or some links about the usage.

    Thank you very much. Sorry but my english is not very good.

    From Signals and Slots
    It is even possible to connect a signal directly to another signal. (This will emit the second signal immediately whenever the first is emitted.)
