How to do it…

In the following example, we will create a new widget project and animate the push button by changing its properties:

1. Let's create a new Qt Widgets Application project. After that, open up mainwindow.ui with Qt Designer and place a button on the main window, as shown here:

2. Open up mainwindow.cpp and add the following line of code at the beginning of the source code:

 #include <QPropertyAnimation>

3. After that, open up mainwindow.cpp and add the following code to the constructor:

QPropertyAnimation *animation = new QPropertyAnimation(ui->pushButton, "geometry");
animation->setDuration(10000);
animation->setStartValue(ui->pushButton->geometry());
animation->setEndValue(QRect(200, 200, 100, 50));
animation->start();
