Javaform Small Form example use label and image

Do a small program, share, give beginners an example bar. I'm just a beginner. Function: Show the location of the mouse .... There are a few pictures, click will change the expression with the label stored text information, with a few labels to save the picture, each label positioned on the form. Just pass the code to the test. Create an image folder under the root directory, put two small expressions, happy.gif,unhappy.gif or modify your path. I'll put the project on the Internet.
