Re: [JAVA2D] Generic ZoomPanel?

[Dmitri Trembovetski]

  I'll ask once again, what java release is this with?

Hi, I tried JXTransformer. Things seem to work at first except: if I embedded the JXTransformer-Panel into a JScrollPanel then - as soon as I shift the view - I get again this dreaded Exception in thread "AWT-EventQueue-1" java.lang.InternalError: Win32OSSD_Lock cannot nest locks

  :-(

What am I missing??? I seem to be so close!

You can try yourself:

                }
                
                JXTransformer transfomer = new JXTransformer(viewer);
                // for some strange reason one can apparently not add a 
JXTransformer directly to
                // a ScrollPanel - if one first adds it to another JPanel 
things seem to work:
                JPanel zoomPanel = new JPanel();
                zoomPanel.add(transfomer);
                
                mainPanel.add(new JScrollPane(zoomPanel,                
                                              
JScrollPane.VERTICAL_SCROLLBAR_AS_NEEDED,

                              BorderLayout.CENTER);
                

double scale = 1.5; AffineTransform at = transfomer.getTransform();

        at.scale(scale, scale);
        transfomer.setTransform(at);
        }
}
