All Implemented Interfaces:

javax.accessibility.Accessible, java.awt.image.ImageObserver, java.awt.MenuContainer, java.lang.Runnable, java.io.Serializable

public class CountdownApplet

extends ParameterApplet

implements java.lang.Runnable

An Applet that shows the current date and time and a countdown to a specified date. The different views on the time fade in and out and move on random paths through the applet.
By clicking on the Applet, the animation can be switched off and the date and remaining days will be shown instead. Documentation on how to use that applet in a website is available here.

Since:

JDK1.1

Version:

1.0

init

public void init()

Initializes the Applet. The most important responsibility is getting the time right and checking whether or not this runs on a Mac.

Overrides:

init in class ParameterApplet

run

public void run()

This Thread tries to load the time from the server. The time must be stored in a file that's accessible over the web, its URL can be specified by the parameter timefile.

Specified by:

run in interface java.lang.Runnable

tick

public void tick()

start

public void start()

Starts the animation.

Overrides:

start in class java.applet.Applet

stop

public void stop()

Stops the animation. The responsible thread finishes and is killed, thus any resources are freed.

Overrides:

stop in class java.applet.Applet

destroy

public void destroy()

Stops the animation. Since most browsers seem to never call this method, its functionality has been moved to stop() and calls to destroy() method are simply forwarded to stop().

Overrides:

destroy in class java.applet.Applet

getAppletInfo

public java.lang.String getAppletInfo()

Shows information about this applet.

Overrides:

getAppletInfo in class ParameterApplet

Returns:

Component.getName()

getParameterInfo

public java.lang.String[][] getParameterInfo()

Shows which parameters are allowed. These parameters are always available, for more parameters override this and handleParams().

Overrides:

getParameterInfo in class ParameterApplet

Returns:

foreground -- RGB-Value -- foreground color, e.g. 0 0 0
background -- RGB-Value -- background color, e.g. 255 255 255
font -- String -- Font for the messages. Default = helvetica
size -- int -- Size of the messages. Default = 12
timefile -- String -- the file with the current time on the server (at startup) finaldate -- String -- the date and time which the applet should count down to fps -- integer -- the framerate of the animation in frames per second displaycount -- integer -- the number of concurrent date-sprites
