Creating a nested animation group

One good example of using a nested animation group is when you have several parallel animation groups and you want to play the groups in a sequential order.

How to do it…

  1. We will use the UI from the previous example and add a few more buttons to the main window, like so:
    How to do it…
  2. First, create all the animations for the buttons, then create an easing curve and apply it to all the animations:
    QPropertyAnimation *animation1 = new QPropertyAnimation(ui->pushButton, "geometry");
animation1->setDuration(3000);
animation1->setStartValue(ui->pushButton->geometry());
animation1->setEndValue(QRect(50, 50, 100, 50));

QPropertyAnimation *animation2 = new QPropertyAnimation(ui->pushButton_2, "geometry");
animation2->setDuration(3000);
animation2->setStartValue(ui->pushButton_2->geometry());
animation2->setEndValue(QRect(150, 50, 100, 50));

QPropertyAnimation *animation3 = new QPropertyAnimation(ui->pushButton_3...
