Method Detail

isActive

public boolean isActive()
Determines if the applet is active. An applet is active just before its start method is called. It becomes inactive just before its stop method is called.

Returns:
true if the applet is active; false otherwise.

getDocumentBase

public URL getDocumentBase()
Gets the URL of the document in which the applet is embedded. For example, suppose an applet is contained within the document:
    http://java.sun.com/products/jdk/1.2/index.html
 
The document base is:
    http://java.sun.com/products/jdk/1.2/index.html
 

Returns:
the URL of the document that contains the applet.

getCodeBase()

getCodeBase

public URL getCodeBase()
Gets the base URL. This is the URL of the directory which contains the applet.

Returns:
the base URL of the directory which contains the applet.
See Also:
getDocumentBase()

getParameter

public String getParameter(String name)
Returns the value of the named parameter in the HTML tag. For example, if an applet is specified as
 <applet code="Clock" width=50 height=50>
 <param name=Color value="blue">
 </applet>
 

then a call to getParameter("Color") returns the value "blue".

Parameters:
name - a parameter name.
Returns:
the value of the named parameter, or null if not set.

getAppletContext

public AppletContext getAppletContext()
Gets a handler to the applet's context.

Returns:
the applet's context.

public void appletResize(int width,
                         int height)
