Variable increment / decrement by pressing the QkeyEvent button

[Creatorczyk]

Hi,

I created a class that aims to increment the variable "x" in the range 0-100 when pressing the "W" button on the keyboard. However, I would like the variable to slowly decrease to zero after releasing the button. During the increment / decrementation, I would like to introduce a delay. Does anyone know how to do it? My current code:

void MoveControler::keyPressEvent(QKeyEvent *event)
{
    try {
        if(event->key() ==Qt::Key_W){
           x+=1;
        }
    } catch (QString exception) {
     QMessageBox::about(nullptr, "Error", exception);
    }
}
