                          com.bbn.openmap.app.OpenMapApplet

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

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 specifed with a different properties file, that file will be used instead.

Field Detail

### PropertiesProperty

    public static final java.lang.String PropertiesProperty

See Also:
  Constant Field Values

### pinfo

    protected final java.lang.String[][] pinfo

Constructor Detail

### OpenMapApplet

    public OpenMapApplet()

Method Detail

### getAppletInfo

    public java.lang.String getAppletInfo()

  Returns information about this 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" } };

  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.

  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.

  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.

  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`.

  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.

### findAndInit

    public void findAndInit(java.lang.Object someObj)

  Called when an object is added to the MapHandler.

### childrenAdded

    public void childrenAdded(java.beans.beancontext.BeanContextMembershipEvent bcme)

  BeanContextMembership interface method. Called when objects are added to the BeanContext.

  Specified by:
    `childrenAdded` in interface `java.beans.beancontext.BeanContextMembershipListener`
  Parameters:
    `bcme` - contains an Iterator that lets you go through the new objects.

### childrenRemoved

    public void childrenRemoved(java.beans.beancontext.BeanContextMembershipEvent bcme)

  BeanContextMembership interface method. Called by BeanContext when children are being removed. Unhooks itself from the objects that are being removed if they are contained within the Frame.

  Specified by:
    `childrenRemoved` in interface `java.beans.beancontext.BeanContextMembershipListener`
  Parameters:
    `bcme` - event that contains an Iterator to use to go through the removed objects.

### findAndUndo

    public void findAndUndo(java.lang.Object someObj)

  Called when an object is removed from the MapHandler.

### getBeanContext

    public java.beans.beancontext.BeanContext getBeanContext()

  Method for BeanContextChild interface.

  Specified by:
    `getBeanContext` in interface `java.beans.beancontext.BeanContextChild`

### setBeanContext

    public void setBeanContext(java.beans.beancontext.BeanContext in_bc)
                        throws java.beans.PropertyVetoException

  Method for BeanContextChild interface.

  Specified by:
    `setBeanContext` in interface `java.beans.beancontext.BeanContextChild`
  Parameters:
    `in_bc` - The context to which this object is being added
  Throws:
    `java.beans.PropertyVetoException`

### addVetoableChangeListener

    public void addVetoableChangeListener(java.lang.String propertyName,
                                          java.beans.VetoableChangeListener in_vcl)

  Method for BeanContextChild interface.

  Specified by:
    `addVetoableChangeListener` in interface `java.beans.beancontext.BeanContextChild`

### removeVetoableChangeListener

    public void removeVetoableChangeListener(java.lang.String propertyName,
                                             java.beans.VetoableChangeListener in_vcl)
