Direct Known Subclasses:

OpenSourceDemoApplet

public abstract class PreviewApplet

extends javax.swing.JApplet

implements PreviewProxy

The preview applet implements the preview proxy interface for JApplets.

Due to the special lifecycle of applets, this implementation must also provide methods to handle the creation of reports. Implementations of this class must implement the getReport() method to provide their fully initialized report definitions.

The getReport() method is called from the init() method.

Constructor Detail

public PreviewApplet()

DefaultConstructor.

Method Detail

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.

A subclass of Applet should override this method if it has any operation that it wants to perform before it is destroyed. For example, an applet with threads would use the init method to create the threads and the destroy method to kill them.

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

See Also:

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

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.

A subclass of Applet should override this method if it has initialization to perform. For example, an applet with threads would use the init method to create the threads and the destroy method to kill them.

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

See Also:

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

getReport

public abstract JFreeReport getReport()

Returns the report that should be displayed in that applet. Make sure, that subsequent calls to this method return the same report instance.

This method is called from PreviewApplet.init(), so make sure that all initialization is done before the init() method is called.

Returns:

the report that should be previewed.

pack

public void pack()

Packs the preview component.

Specified by:

pack in interface PreviewProxy

dispose

public void dispose()

Disposes the preview component.

Specified by:

dispose in interface PreviewProxy

createDefaultCloseAction

public javax.swing.Action createDefaultCloseAction()

Creates a default close action.

Specified by:

createDefaultCloseAction in interface PreviewProxy

Returns:

The close action.

setTitle

public void setTitle(java.lang.String title)

Sets the title for the preview component.

Specified by:

setTitle in interface PreviewProxy

Parameters:

title - the title.

getResources

public java.util.ResourceBundle getResources()

Retrieves the resources for this PreviewFrame. If the resources are not initialized, they get loaded on the first call to this method.

Returns:

this frames ResourceBundle.

getBase

public PreviewProxyBase getBase()

Returns the preview proxy.

Specified by:

getBase in interface PreviewProxy

Returns:

The proxy.

close

public void close()

Closes the applet and finishes all worker threads.

Specified by:

close in interface PreviewProxy

See Also:

PreviewProxy.close()
