Scrollable JDesktopPane?

Solutons:


I’ve used JavaWorld’s solution by creating my own JScrollableDesktopPane.

Javaworld’s JScrollableDesktopPane is no longer available on their website. I managed to scrounge up some copies of it but none of them work.

A simple solution I’ve derived can be achieved doing something like the following. It’s not the prettiest but it certainly works better than the default behavior.

public class Window extends Frame {
    JScrollPane scrollContainer = new JScrollPane();
    JDesktopPane mainWorkingPane = new JDesktopPane();

    public Window() {
        scrollContainer.setViewportView(mainWorkingPane);

        addComponentListener(new ComponentAdapter() {
            public void componentResized(ComponentEvent evt) {
                revalidateDesktopPane();
            }
        });
    }

    private void revalidateDesktopPane() {
        Dimension dim = new Dimension(0,0);
        Component[] com = mainWorkingPane.getComponents();
        for (int i=0 ; i<com.length ; i++) {
            int w = (int) dim.getWidth()+com[i].getWidth();
            int h = (int) dim.getHeight()+com[i].getHeight();
            dim.setSize(new Dimension(w,h));
        }
        mainWorkingPane.setPreferredSize(dim);
        mainWorkingPane.revalidate();
        revalidate();
        repaint();  
    }
}

The idea being to wrap JDesktopPane in a JScrollPane, add a resize listener on the main Frame and then evaluate the contents of the JDesktopPane on resize (or adding new elements).

Hope this helps someone out there.

I’ve found this : http://www.javaworld.com/javaworld/jw-11-2001/jw-1130-jscroll.html?page=1

It’s a nice tutorial with lots of explanations and infos on Swing & so, which permits to create a JscrollableDesktopPane with lots of stuff.

You will need to modify a bit some parts of code to fulfill your requirements.

Enjoy !
