书籍"Java_面向事件编程"的附带光盘代码

This program allows the user to create several different types of objects on
the canvas.  They can change the color of the last shape created by using 
the buttons along the side of the window.  The size of the next shape created
can be set using the slider.  This program demonstrates the use of the JSlider
and JComboBox GUI components.
