要するに、このコードはメイン関数にあり、これはうまくいきます。このコードは、2つのグラフィック要素をスワップします。 QTimerはメイン関数の外では機能しません
QTimer timer;
timer.setTimerType(Qt::PreciseTimer);
timer.setInterval(1000.0/30.0);
timer.setSingleShot(false);
// ====================== MOVE 4 in POS of 1 ==========================
QPointF centre(QLineF(button1->pos(), button4->pos()).pointAt(0.5));
QPointF positionBut4 = button4->pos();
MyPointF centreSwap4(0, &positionBut4, ¢re);
button4->myPointF = ¢reSwap4;
QObject::connect(&timer, SIGNAL(timeout()), ¢reSwap4, SLOT(updateDownRight()));
QObject::connect(¢reSwap4, SIGNAL(positionChanged()), button4, SLOT(slotMoveCircle()));
// ====================== MOVE 4 in POS of 1 ==========================
// ====================== MOVE 1 in POS of 4 ==========================
QPointF positionBut1 = button1->pos();
MyPointF centreSwap1(0, &positionBut1, ¢re);
button1->myPointF = ¢reSwap1;
QObject::connect(&timer, SIGNAL(timeout()), ¢reSwap1, SLOT(updateUpLeft()));
QObject::connect(¢reSwap1, SIGNAL(positionChanged()), button1, SLOT(slotMoveCircle()));
// ====================== MOVE 1 in POS of 4 ==========================
timer.start();
QTimer::singleShot(3000, Qt::PreciseTimer, &timer, SLOT(stop()));
私が言う(QTimerが動作することを拒否(コードを短縮し、ちょうどそれらへのポインタを与えることによって要素にスワップを実行するために)関数にメインのうち、コードのこの部分を入れたいときしかし、それはです)アクティブしかし、タイムアウトがトリガーされていません。
void animateSwap(QGraphicsRectWidget *w1, QGraphicsRectWidget *w2, QTimer &timer)
{
QGraphicsRectWidget *button4, *button1;
if (w1->x() > w2->x())
{
button4 = w2;
button1 = w1;
}
else
{
button4 = w1;
button1 = w2;
}
// ====================== MOVE w2 in POS of w1 ==========================
QPointF centre(QLineF(button1->pos(), button4->pos()).pointAt(0.5));
QPointF positionBut4 = button4->pos();
MyPointF centreSwap4(0, &positionBut4, ¢re);
button4->myPointF = ¢reSwap4;
QObject::connect(&timer, SIGNAL(timeout()), ¢reSwap4, SLOT(updateDownRight()));
QObject::connect(¢reSwap4, SIGNAL(positionChanged()), button4, SLOT(slotMoveCircle()));
// ====================== !MOVE w2 in POS of w1 ==========================
// ====================== MOVE w1 in POS of w2 ==========================
QPointF positionBut1 = button1->pos();
MyPointF centreSwap1(0, &positionBut1, ¢re);
button1->myPointF = ¢reSwap1;
QObject::connect(&timer, SIGNAL(timeout()), ¢reSwap1, SLOT(updateUpLeft()));
QObject::connect(¢reSwap1, SIGNAL(positionChanged()), button1, SLOT(slotMoveCircle()));
// ====================== MOVE w1 in POS of w2 ==========================
timer.start();
qDebug() << timer.isActive();
QTimer::singleShot(3000, Qt::PreciseTimer, &timer, SLOT(stop()));
}
UPDATE: 今では動作します:
void animateSwap(QGraphicsRectWidget *w1, QGraphicsRectWidget *w2, QTimer &timer, int cycles = 1)
{
QGraphicsRectWidget *button4, *button1;
if (w1->x() > w2->x())
{
button4 = w2;
button1 = w1;
}
else
{
button4 = w1;
button1 = w2;
}
// ====================== MOVE w2 in POS of w1 ==========================
QPointF centre(QLineF(button1->pos(), button4->pos()).pointAt(0.5));
QPointF positionBut4 = button4->pos();
MyPointF *centreSwap4 = new MyPointF(0, &positionBut4, ¢re);
button4->myPointF = centreSwap4;
QObject::connect(&timer, SIGNAL(timeout()), centreSwap4, SLOT(updateDownRight()));
QObject::connect(centreSwap4, SIGNAL(positionChanged()), button4, SLOT(slotMoveCircle()));
// ====================== !MOVE w2 in POS of w1 ==========================
// ====================== MOVE w1 in POS of w2 ==========================
QPointF positionBut1 = button1->pos();
MyPointF *centreSwap1 = new MyPointF(0, &positionBut1, ¢re);
button1->myPointF = centreSwap1;
QObject::connect(&timer, SIGNAL(timeout()), centreSwap1, SLOT(updateUpLeft()));
QObject::connect(centreSwap1, SIGNAL(positionChanged()), button1, SLOT(slotMoveCircle()));
// ====================== MOVE w1 in POS of w2 ==========================
timer.start();
qDebug() << timer.isActive();
QTimer::singleShot(3000 * cycles, Qt::PreciseTimer, &timer, SLOT(stop()));
}
その他のコードも追加できますか?メインの内容 – RvdK
