public class Viewer
extends quadbase.reportdesigner.PageViewer.swing.CApplet

The Viewer class is the entry point in using the Page Viewer to view a report. The Page Viewer provides the mechanism to view the report page by page, and in doing so, minimizes the amount of resources needed on the client application. The idea is that Espress Manager is being ran at some server and the client terminal simply requests to view a certain page of a report. This puts the client in a situation where it only need to worry about drawing and displaying the report on screen.

Method Detail

init

public void init()

internal use only

Overrides:

init in class java.applet.Applet

main

public static void main(java.lang.String[] argv)

This is the entry point of the Page Viewer application. Pass in a String array of one argument that contains a file name to a .page file to start the application viewing a certain page of a report.
The .page file is what gets streamed by the Report Server to the Page Viewer. You may also use the export() method from QbReport to export specific pages of the report in .page format.

getComponent

public static java.awt.Component getComponent(java.applet.Applet applet,
