public final class SplashScreen
extends java.awt.Frame

Present a simple graphic to the user upon launch of the application, to provide a faster initial response than is possible with the main window.

Adapted from an item on Sun's Java Developer Connection.

This splash screen appears within about 2.5 seconds on a development machine. The main screen takes about 6.0 seconds to load, so use of a splash screen cuts down the initial display delay by about 55 percent.

Constructor Detail

SplashScreen

public SplashScreen(java.lang.String aImageId)
Parameters:
aImageId - must have content, and is used by Class.getResource to retrieve the splash screen image.
Method Detail

splash

public void splash()
Show the splash screen to the end user.

Once this method returns, the splash screen is realized, which means that almost all work on the splash screen should proceed through the event dispatch thread. In particular, any call to dispose for the splash screen must be performed in the event dispatch thread.
