[JAVA2D] Adding scroll Pane to imageManipulator application

[Braun-Friedman, David]

Well I wrote earlier for some help on figuring out how to get my program to pan an 
image after being zoomed by using scroll bars.  As of now I have gotten the scroll 
abrs to appear after a zoom but they don't appear until the mouse is moved over 
them....Also some of the other functionality doesn't work properly while the 
scrollPane is implemented.  I will post some of the code of my ImageManip2D class 
where the scrollpane is decalred and created.  Any help would be great....i was told I 
may be having such problems because my component class, imageCanvas is custom designed 
and is not one of those created inside the JAVA API.  Anyways, I'll leave it at that.  
Thanks.

 

 

 

 

 

public class ImageManip2D extends ImageViewer2D 

                                     /*implements PropertyChangeListener*/{

    //protected JTextArea vmMessageBar;

    //protected JTextArea pzMessageBar;

    //protected JTextArea mnpMessageBar;

    protected JFrame ilFrame;

    protected PanZoom panZoom;

    //protected GeomManip manip;

    protected JFrame  lensFrame;

    protected JFrame manipFrame;

    protected JFrame filtersFrame;

    protected LensPanel lensPanel;

            protected JScrollPane scrollPane;

    public static void  main(String[] args){ ImageManip2D iv = new ImageManip2D();}

 

    public ImageManip2D() { init(); }

    public void init(){

       panZoom = new PanZoom((ImageManipulator)viewerPane);

       //this.updateMessageBar();

       //viewerPane.addPropertyChangeListener(this);

      

       repaint();

    }

 

    protected void createGUI(){

       //createImageLoader();

       ViewerMenuBar viewerMenuBar = new ViewerMenuBar();

       setJMenuBar((JMenuBar)viewerMenuBar);

       Dimension ssize= Toolkit.getDefaultToolkit().getScreenSize();

 

       this.setLocation((ssize.width/8),

                         (ssize.height/8));

       this.setSize((int)(ssize.width*3/4.0), (int)(ssize.height*3/4.0));

 

       viewerPane = new ImageCanvas2D();

 

       JPanel mbpan = new JPanel();

 

       scrollPane = new JScrollPane();

       /*this.getContentPane().add(scrollPane);    

       scrollPane.add(viewerPane);

       this.getContentPane().add(viewerPane);

       */

       this.getContentPane().add(new JScrollPane(viewerPane));

       

       this.getContentPane().add(mbpan, BorderLayout.SOUTH);

       JButton filters = new JButton("Filters");

       mbpan.add(filters);

 

      this.show();

       this.repaint();
