Class AppletEnvironment

java.lang.Object
  |
  +--netx.jnlp.runtime.AppletEnvironment

All Implemented Interfaces:

java.applet.AppletContext, java.applet.AppletStub

public class AppletEnvironment

extends java.lang.Object

implements java.applet.AppletContext, java.applet.AppletStub

The applet environment including stub, context, and frame. The default environment puts the applet in a non-resiable frame; this can be changed by obtaining the frame and setting it resizable.

Constructor Summary

AppletEnvironment(JNLPFile file, AppletInstance appletInstance)
Create a new applet environment for the applet specified by the JNLP file.

Method Summary

void	appletResize(int width, int height)
void	destroy() Disposes the applet's resources and disables the applet environment from further use; after calling this method the applet stub and context methods throw IllegalStateExceptions.

java.applet.AppletContext	getAppletContext()
java.awt.Frame	getAppletFrame() Returns the frame that contains the applet.
java.util.Enumeration	getApplets() Returns an enumeration that contains only the applet from the JNLP file.
java.applet.AudioClip	getAudioClip(java.net.URL location) Returns an audio clip.
java.net.URL	getCodeBase()

Constructor Detail

AppletEnvironment

public AppletEnvironment(JNLPFile file,
                         AppletInstance appletInstance)

Create a new applet environment for the applet specified by the JNLP file.

Method Detail

destroy

public void destroy()

Disposes the applet's resources and disables the applet environment from further use; after calling this method the applet stub and context methods throw IllegalStateExceptions.

getAppletFrame

public java.awt.Frame getAppletFrame()

Returns the frame that contains the applet. Disposing this frame will destroy the applet.

startApplet

public void startApplet()

Initialize, start, and show the applet.

getApplet

public java.applet.Applet getApplet(java.lang.String name)

Returns the applet if the applet's name is specified, otherwise return null.

Specified by:

getApplet in interface java.applet.AppletContext

getApplets

public java.util.Enumeration getApplets()

Returns an enumeration that contains only the applet from the JNLP file.

Specified by:

getApplets in interface java.applet.AppletContext

getAudioClip

public java.applet.AudioClip getAudioClip(java.net.URL location)

Returns an audio clip.

Specified by:

getAudioClip in interface java.applet.AppletContext

showDocument

public void showDocument(java.net.URL uRL)

Not implemented yet.

Specified by:

showDocument in interface java.applet.AppletContext

showDocument

public void showDocument(java.net.URL uRL,
                         java.lang.String str)

Not implemented yet.

Specified by:

Not implemented yet.

Specified by:

showStatus in interface java.applet.AppletContext

setStream

public void setStream(java.lang.String key,
                      java.io.InputStream stream)
