    When you say you "can’t" is because you’re getting an error or because you don’t know how to do it? Have you ever tried to reimplement the method keyPressEvent in your class Tabuleiro?

  • I have reimplemented, but when running the application does not call the method.

  • Implemented where, how? Not in the code you shared.

You need to include the Qkeyevent class and reimplement the function void keyReleaseEvent(QKeyEvent* event), for your keyboard events to be recognized.
