HACK

public boolean isDirLink(File f) {

try {

if(f.getName().toLowerCase( ).endsWith(".lnk")) {

LnkParser parser = new LnkParser(f);

if(parser.isDirectory( )) {

return true;

}

}

} catch (Exception ex) {

System.out.println("exception: " + ex.getMessage( ));

ex.printStackTrace( );

}

return false;

}

And finally, here’s a test class that will build a new shortcut enabled file

chooser. It creates a normal file chooser, and then sets the

FileSystemView to

the new shortcut subclass. It also sets the modified version of the

ShortcutFileView:

public class ShortcutTest {

public static void main(String[] args) throws Exception {

FileSystemView fsv = new ShortcutFileSystemView( );

JFileChooser chooser = new JFileChooser( );

chooser.setFileSystemView(fsv);

chooser.setFileView(new ShortcutFileView( ));

chooser.showOpenDialog(null);

}

}

Figure 4-5 shows the JFileChooser displaying a shortcut that will behave like

a real Windows shortcut when clicked.
