keyPressEvent QKeyEvent => lose keys / don't get all the events / running QMovie

Salvator

Hi @all,
I connect a BC-Code scanner to my Raspberry PI, when I scan, the data will arrived in the app as keyevent. That is working fine untill I start QMovie, when the movie (it is a small .gif about 100kb) is running I don't get all keys.
The lost keys can be at begining, in the middle or at the end of the reading code.

I catch the keys in the application::notify() - event, so I hoped to get all keyevents, also the focus will change between the widgets.

bool CMyApp::notify(QObject *receiver, QEvent *event)
{
  try
  {
    if (event->type() == QEvent::KeyPress)
    {
      QKeyEvent * keyevent = dynamic_cast<QKeyEvent *>(event);
      qDebug() << "keycode GO text >>" << keyevent->text();
      qDebug() << "keycode GO key >>" << keyevent->key();
      pMainWindow->MyKeyEvent(keyevent);
      return(true);
      ...

the QMovie I start like this

if(pDisplayStart->psMovie == nullptr)
{
  pDisplayStart->psMovie = new QMovie(":/Animation/Test.gif");
}
pDisplayStart->psMovie->setSpeed(80);
pDisplayStart->ui->label1->setMovie(pDisplayStart->psMovie);
pDisplayStart->psMovie->start();

What can I do to get all the keyevents?
When the QMovie is stopped so I get all keys again.
Thank you for helping hand.

kind regards
Salva
