All Implemented Interfaces:

javax.accessibility.Accessible, FigDrawableEnumerator, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable

public class JFigViewerBean

extends javax.swing.JPanel

implements FigDrawableEnumerator

A FIG file viewer implemented as a Java Bean component. The FIG file is specified via an URL with any of the standard protocols (file:, http:, ftp:, resource:, ... ).

A popup-menu allows to specify several options. The viewer implements mouse-dragging and a few keyboard shortcuts. Use the setURL() method to specify the FIG file. For example, JFigViewerBean viewer = new JFigViewerBean(); viewer.setPreferredSize( new Dimension( 600, 500 ) ); viewer.setURL( "file://C:/temp/house.fig" ); JFrame frame = new JFrame( "FIG Bean Demo" ); frame.getContentPane().add( "Center", viewer ); frame.pack(); frame.show(); viewer.doZoomFit();

set a new canvas for this bean. You would only need to call this method if you plan to provide your own FigCanvas implementation instead of the default FigSwingCanvas.

getObjectList

public FigObjectList getObjectList()

get a reference to our internal object list. Direct access to the object list allows to enumerate and to change the list; for example, to delete or add objects, or to change their attributes and coordinates. (Note that you may have to call doFullRedraw() after modifying the object list).

setObjectList

public void setObjectList(FigObjectList tmp)

set a new object list. Note that you may want to call doFullRedraw() and some of the zoom and panning functions after setting a new object list, in order to acutally display the new objects...
