All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.beans.beancontext.BeanContextChild, java.beans.beancontext.BeanContextMembershipListener, java.io.Serializable, java.util.EventListener, javax.accessibility.Accessible, javax.swing.RootPaneContainer

public class OpenMapApplet
extends javax.swing.JApplet
implements java.beans.beancontext.BeanContextMembershipListener, java.beans.beancontext.BeanContextChild

OpenMap Applet. Uses the MapHandler, via BeanContextMembershipListener methods to lay out the MapPanel and JMenuBar. Creates a PropertyHandler that will look for the openmap.properties file in the codebase. If the

 PROPERTIES
 

applet parameter is specified with a different properties file, that file will be used instead.

Method Detail

getAppletInfo

public java.lang.String getAppletInfo()

Returns information about this applet.

Overrides:

getAppletInfo in class java.applet.Applet

Returns:

a string containing information about the author, version, and copyright of the applet.

Since:

JDK1.0

getParameterInfo

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

Returns information about the parameters that are understood by this applet.

Each element of the array should be a set of three Strings containing the name, the type, and a description. For example:

 String pinfo[][] = {
     {
         "fps",
         "1-10",
         "frames per second"
     },
     {
         "repeat",
         "boolean",
         "repeat image loop"
     },
     {
         "imgs",
         "url",
         "images directory"
     }
 };
 

Overrides:

getParameterInfo in class java.applet.Applet

Returns:

an array describing the parameters this applet looks for.

Since:

JDK1.0

init

public void init()

Called by the browser or applet viewer to inform this applet that it has been loaded into the system. It is always called before the first time that the start method is called.

The implementation of this method provided by the Applet class does nothing.

Overrides:

init in class java.applet.Applet

Since:

JDK1.0

See Also:

Applet.destroy(), Applet.start(), Applet.stop()

start

public void start()

Called by the browser or applet viewer to inform this applet that it should start its execution. It is called after the init method and each time the applet is revisited in a Web page.

Overrides:

start in class java.applet.Applet

Since:

JDK1.0

See Also:

Applet.destroy(), Applet.init(), Applet.stop()

stop

public void stop()

Called by the browser or applet viewer to inform this applet that it should stop its execution. It is called when the Web page that contains this applet has been replaced by another page, and also just before the applet is to be destroyed.

Overrides:

stop in class java.applet.Applet

Since:

JDK1.0

See Also:

Applet.destroy(), Applet.init()

destroy

public void destroy()

Called by the browser or applet viewer to inform this applet that it is being reclaimed and that it should destroy any resources that it has allocated. The stop method will always be called before destroy.

Overrides:

destroy in class java.applet.Applet

Since:

JDK1.0

See Also:

Applet.init(), Applet.start(), Applet.stop()

findAndInit

public void findAndInit(java.util.Iterator it)

The method called by BeanContextMembershipListener methods to find components in the MapHandler.
