如何使图像查看器摆动？

Question

I am trying to make an image Viewer like the one shown in the figure below:-

Before i can start i have following questions in mind :-

1. How would i check for the number of images in the target folder so that i can iterate and include all the images in my app.

2. Secondly,i am thiking to scale the images down to 75x75 .But what i can't think is that how will i slide the images as scrollbar is moved To be specific,what is the appropriate container for those 75x75 images queue and how that queue is shifted to left or right?(I already know how to get current scrollbar value and add event listeners on it to respond)

Answer 1

To check the number of images in the target folder you can use the File class.

As for the container you might need to create the animation your self. There is no a container ready for doing so.

This site ( and book ) has some ideas about it. I don't know how out-dated it might be though

Answer 2

Unless I am misunderstanding, making a scrolling list of images is quite simple.

First, create a JList with a datamodel that allows images.

A great example is shown here: Java drag and drop images in a list

Second, add the JList to a JScrollPane.

The scaling aspect can be easily performed using Scalr: http://www.thebuzzmedia.com/software/imgscalr-java-image-scaling-library/
