Installing Event Filters

[Dumbledore]

Good evening,

I have code as follows:

MChat::MChat(QMainWindow *parent) : QMainWindow(parent) {
  setupUi(this);
  inputChat->installEventFilter(this);
  connect(reinterpret_cast<QObject*>(this), SIGNAL(pressedReturn()),
	  reinterpret_cast<QObject*>(sendButton), SLOT(animateClick()));
}
 
bool MChat::eventFilter(QObject *obj, QEvent *event) {
  if (event->type() == QEvent::KeyPress) {
    QKeyEvent *keyEvent = reinterpret_cast<QKeyEvent *>(event);
    if ( keyEvent->key() == Qt::Key_Return ) {
      emit pressedReturn();
      return true;
    }
    else {
      // continue standard event processing
      return QObject::eventFilter(obj, event);
    }
  }
}

MChat::MChat(QMainWindow *parent) : QMainWindow(parent) {
  setupUi(this);
  inputChat->installEventFilter(this);
  connect(reinterpret_cast<QObject*>(this), SIGNAL(pressedReturn()),
	  reinterpret_cast<QObject*>(sendButton), SLOT(animateClick()));
}

bool MChat::eventFilter(QObject *obj, QEvent *event) {
  if (event->type() == QEvent::KeyPress) {
    QKeyEvent *keyEvent = reinterpret_cast<QKeyEvent *>(event);
    if ( keyEvent->key() == Qt::Key_Return ) {
      emit pressedReturn();
      return true;
    }
    else {
      // continue standard event processing
      return QObject::eventFilter(obj, event);
    }
  }
}

I personally don't think this is good. I'd like to have the eventFilter as a method of inputChat. But to do this I'd have to directly edit the code generated by uic. At least, that's the only way I know. Perhaps someone could show me a better way?
