About "virtual directory" and ShellFolder

Question

hi, everyone!
i'm a freshman to this language, and met some trouble last night.
i'm designing a small program by using jfc.
the project is just like "ms resources explorer", containing a tree view.
i wanna create a root node which represents desktop, including three children:
"My Computer", "Network neighbor" and "My Document".
the last one is a real directory in windows,
but the other two don't exist eventually.
i wanna get such, i called, "virtual directorys" from system, including their icons.
the root directory, you know, only represents its logical disc,
such as A:\, C:\, D:\ and etc.,
not the whole system like "My Computer".
i searched the api reference,
and found that the "JFileChooser" class contains a method named
"getFileSystemView()", through which we can get the "FileSystemView" object
of a file or a directory, including "virtual directory".
i checked the source code,
and found a class named "ShellFolder" inheriting from the "File" class,
but it's not published in JDK's api--i don't know why.
now the question is,
are there any simple classes can implement the "virtual directory" like "My Computer" or "Network Neighbor" besides "JFileChooser"?
thanks a lot.
by the way, "FileSystemView" and "ShellFolder" are all abstract class.
references:
javax.swing.JFileChooser;
javax.swing.filechooser.FileSystemView;
sun.awt.shell.ShellFolder;

Hi,
try this!
It's a simple System.out.println() of FileSystemView and you only have to add it in your JTree...
import javax.swing.filechooser.FileSystemView;
import java.io.File;
public class ViewFilesDirs {
public ViewFilesDirs() {
FileSystemView view = FileSystemView.getFileSystemView();
System.out.println("Default Dir: " + view.getDefaultDirectory());
System.out.println("Home Dir: " + view.getHomeDirectory());
System.out.println("---");
File[] fs = view.getFiles(view.getHomeDirectory(), true);
for (int ind=0; ind<fs.length;ind++)
System.out.println("File/Directory: " + fs[ind]);
public static void main(String[] args) {
ViewFilesDirs untitled11 = new ViewFilesDirs();
if you have problem, i'm here!!! :)
bye bye!!!
