public class appWrapper
extends Applet
implements AppletStub, Runnable

The appWrapper is thought to make the applet itself independent from the original context. This is necessary to be able to detach the applet from the web browsers window without disconnecting it from events. Note: This applet should work with any applet without changes.

    <PARAM NAME="applet" VALUE="applet">

  Defines the applet to be loaded by the appWrapper. State the applet class name without ".class"!

    <PARAM NAME="startButton" VALUE="text">

  If this parameter is set the applet is not loaded until the user presses the button. This decreases first time download delay. The text given as value to the parameter is shown on the button. While loading the applet the message "Loading ..." is shown on the button.

    <PARAM NAME="stopButton" VALUE="text">

  This parameter defines the button text when the applet is loaded. When pressing the button while the applet is running this causes the applet window to be destroyed and the applet is stopped.

    <PARAM NAME="frameTitle" VALUE="text">

  The frameTitle is the text that is shown in the title bar of the applet window.
