public class SplashWindow

extends javax.swing.JWindow

Class SplashWindow defines a splash window to be shown while a program is constructing and loading its GUI. The size of the display screen may also be queried via the static 'getDisplayScreenSize()' method. A simple "Program loading..." splash window may be displayed by using the no-parameter constructor and then calling 'show()' in the 'main()' method of the program. The 'close()' method should be called just before the program GUI is made visible. See the various constructors for other possible variations on the window's contents and position.
