Main window not responding after adding QPushButton

Question

I'm currently making an AI to "Snake". After adding QPushButton to my QMainWindow there is no response from window for pressing any key.

void MainWindow::keyReleaseEvent(QKeyEvent* event)
{
   g->key_event(event);
}

That's how I'm injecting QKeyEvent into my game class. Everything works without any QPushButton.

The button might have the focus and therefore receive the events. — SteakOverflow, Feb 09 '18 at 13:47

It could be that the problem is related to your override method not passing the call up to the superclass. You might want to do it like this, instead:

void MainWindow::keyReleaseEvent(QKeyEvent* event)
{
    QMainWindow::keyReleaseEvent(event);
    g->key_event(event);
}
