eventFilter in Console App

QT Version: 4.4.1
OS: RHEL 5

I am attempting to create a console application that uses QLocalServer/QLocalSocket for interprocess communication.

In the program, I stay in the event loop waiting for connections.

If the user presses a key, I want to exit the program.

I have remplemented the eventFilter method and added a installEventFilter(this) call to the constructor of the SNOOPER class:

Code:

---

class SNOOPER: public QObject
{
    Q_OBJECT
 
    public:
        SNOOPER(QString sIP);                // Constructor
        ~SNOOPER();                            // Destructor
...        
 
        bool eventFilter( QObject *o, QEvent *e );
 
    public slots:
        void connectClient();
        void readParts();
};
 
 bool SNOOPER::eventFilter( QObject *o, QEvent *e )
 {
     bool bRval = false;
 
    if (e->type() == QEvent::KeyPress)
    {
        qDebug("KeyPress event detected.");
        bRval = true;
        exit(0);
    }
    else
    {
        qDebug("Non-KeyPress event detected.");
    }
    return bRval;
 }

---

I received the following output when I run the program, but I do not get any key events:

Code:

---

Non-KeyPress event detected.
Non-KeyPress event detected.

Please let me know what I am missing.

Thanks!

KeyPressEvents are sent only to widgets therefore console applications won't receive them.

Is there a good way to trap <control>-C so that I can at least shutdown the QLocalServer if they exit that way?

Currently, it works like this:
1. Start the program.
2. Hit Control-C to stop it.
3. Start it again, and I get a socket busy error.
4. Start it again and it works.

If I could somehow skip step 3, I'd be alright.

Use signal() or sigaction() depending on the system you are using.
