Question

我有一个计时器，我在start（）函数中启动。它控制一个timerEvent函数，但我无法阻止它。我试过killTimer（），但我不知道它的ID。

startTimer(60);
void Game::timerEvent(QTimerEvent *){}
killTimer(0);

该功能只是检查按键。 killTimer（0）不会返回错误，但每隔一个id都会返回错误，但它仍然不会杀死计时器。有没有办法通过函数获取计时器ID？错误：QObject :: killTimer（）：错误：定时器id 1对于对象0x1c81bff8（游戏）无效，计时器尚未被杀死

编辑：//小例子

start(){ 
scene->setSceneRect(0,0,1200,800);
setScene(scene);

timerId = this->startTimer(60);
}

//when the game ends, i call konec();

konec(){
 if(winner==1 || winnerCPU==1){
     removeAllItems(); // this function attemps to stop the timer
     scene->setSceneRect(0,0,1200,800);
     setScene(scene);
     }

     //i have this on a timer also, it stats with start() but i stop the 
     //timer in removeAllItems()
     // may this cause multiple timers IDs?
     QRectF rect = scene->sceneRect();
     rect.translate(avto->speed, 0);
     scene->setSceneRect(rect);

removeAllItems(){ /

timer->stop();
timer2->stop();
mtimer->stop();
shifter->stop();
time->stop();
move_timer->stop();
this->killTimer(timerId);



QList<QGraphicsItem *> stvari = scene->items();
for(int i=0, n=stvari.size();i<n;i++){
    if((typeid(*(stvari[i]))==typeid(Button)) || (typeid(*
(stvari[i]))==typeid(QTableView)) ||
            (typeid(*(stvari[i]))==typeid(Count)) || (typeid(*
(stvari[i]))==typeid(Linija)) ||
            (typeid(*(stvari[i]))==typeid(Player)) || (typeid(*
(stvari[i]))==typeid(Player2)) ||
            (typeid(*(stvari[i]))==typeid(Sred)))
            scene->removeItem(stvari[i]);}
}

Answer 1

  int timerId;
  timerId = startTimer(60);
  killTimer(timerId);

使用startTimer（）启动kill计时器
