Let's run this code. You will see the huge HelloWorld.png image. Further, you will see that you can scroll it by swiping.

How it works...

You create an instance of the ScrollView class by using the create method without arguments.

You set the direction of the scroll view by using the setDirection method. In this case, we want to scroll up and down, and left and right, so you should set ui::ScrollView::Direction::BOTH. This implies that we can scroll in both the vertical and the horizontal directions. If you want to scroll just up and down, you set ui::ScrollView::Direction::VERTICAL. If you want to scroll just left and right, you set ui::ScrollView::Direction::HORIZONTAL.

If you want to bounce when it is scrolled at the edge of the area, you should set true by using the setBounceEnabled method.

You will provide the content to be displayed in the scroll view. Here, we have used HelloWorld.png that has been scaled twice.

You have to specify the size of the content in the scroll view by using the setInnerContainerSize method. In this case, we specify double the size of HelloWorld.png in the setInnerContainerSize method

You have to specify the size of the scroll view by using the setContentSize method. In this case, we specify the original size of HelloWorld.png by using the setContentSize method.
