Qt embedded processes not all keys

Question

I use Qt Embedded and I have a board with some keypad. I use eventFilter and check for QKeyEvent for my widget, but for only two buttons Qt doesn't react to. eventFilter isn't called. Here is code:

bool eventFilter(QObject* parent, QEvent* event)
{
  qDebug() << "entered";
  switch (event->type())
  {
    case QEvent::KeyPress:
    {
      QKeyEvent* key_event = qobject_cast<QKeyEvent*>(event);
      qDebug() << key_event->key();
    }
  }
}

But physic keys work and driver too. I can listen it from /dev/event2.

Has anybody struggled with it? Thanks.

You're going to need to add some more relevant details or no one is going to be able to help you... — Ross, Apr 29 '14 at 16:15
Your widget must have focus to get events. Add an application filter if you want to see all events. — artless noise, Apr 30 '14 at 15:03

As a test, you could try installing a QWSServer::KeyboardFilter before instantiating the App. And see if the QWSServer is getting the key.

If not, then I would suggest looking at the keymap used by the QWS server (look up environment variable QWS_KEYBOARD). Both the default US key map and in my case, the custom gb.qmap didn't map all the keys.
