Class Viewer

java.lang.Object
  jfig.gui.Viewer

All Implemented Interfaces:

java.awt.event.ActionListener, java.util.EventListener, FigBasicEditor, FigCanvasListener, FigDrawableEnumerator, java.awt.event.KeyListener

public class Viewer

extends java.lang.Object

implements FigBasicEditor, FigDrawableEnumerator, FigCanvasListener, java.awt.event.KeyListener, java.awt.event.ActionListener

the standalone jfig viewer.

A viewer for FIG 3.1 and (planned) FIG 3.2 files built on top of the jfig class library. The user interface consists of the main 'object canvas' and some buttons (open file, open http, zooming, etc.). This class is intended to display a single FIG file. Use the presentation viewer to view and browse jfig presentations.

To integrate the viewer with your own applications, use the following example code:

   ...
   jfig.gui.Viewer viewer = new jfig.gui.Viewer();
   viewer.doParseFile( "myfile.fig" );
   ... 
   viewer.doParseURL( "http://myserver/mypath/myfile.fig" );
   ...
