How to wait for QPropertyAnimation to finish

[-GSG-]

My goal is to make the following algorithm:

1. Compute the result of the rule
2. Play an animation
3. After the animation has been played -> go to the next rule

I can't figure out how to implement the waiting from (2) -> (3)

here is the algorithm:

while (running) {
    doRule(CurrentRow, CurrentCol, 1, running);
    currentPosition = getPointer();

    movingArrow = new QPropertyAnimation(ui->arrow, "geometry");
    movingArrow->setDuration(125 * arrowSpeed);
    movingArrow->setStartValue(arrowPos(lastPosition));
    movingArrow->setEndValue(arrowPos(currentPosition));
    movingArrow->start();

    QObject::connect(movingArrow, &QPropertyAnimation::finished,
                     this, &TuringWindow::deleteAnimation);

    lastPosition = currentPosition;
}

Hi and welcome to devnet,

Use the finished signal of QPropertyAnimation to trigger the execution of the text rule.
No need for such a tight loop.

@SGaist Thanks, it worked. I got rid of the while loop and connected the finished signal of QPropertyAnimation to the function of running the programm which runs the rules.
