public class Win32FileSystemView

extends javax.swing.filechooser.FileSystemView

This class is necessary due to an annoying bug on Windows NT where instantiating a JFileChooser with the default FileSystemView will cause a "drive A: not ready" error every time. I grabbed the Windows FileSystemView impl from the 1.3 SDK and modified it so as to not use java.io.File.listRoots() to get fileSystem roots. java.io.File.listRoots() does a SecurityManager.checkRead() which causes the OS to try to access drive A: even when there is no disk, causing an annoying "abort, retry, ignore" popup message every time we instantiate a JFileChooser! Instead of calling listRoots() we use a straightforward alternate method of getting file system roots.

Since:

ARGO0.9.8

Method Detail

isRoot

public boolean isRoot(java.io.File f)

Returns true if the given file is a root.

Overrides:

isRoot in class javax.swing.filechooser.FileSystemView

createNewFolder

public java.io.File createNewFolder(java.io.File containingDir)
                             throws java.io.IOException

creates a new folder with a default folder name.

Specified by:

createNewFolder in class javax.swing.filechooser.FileSystemView

java.io.IOException

isHiddenFile

public boolean isHiddenFile(java.io.File f)

Returns whether a file is hidden or not. On Windows there is currently no way to get this information from io.File, therefore always return false.

Overrides:

isHiddenFile in class javax.swing.filechooser.FileSystemView

getRoots

public java.io.File[] getRoots()

Returns all root partitians on this system. On Windows, this will be the A: through Z: drives. Note - This appears to bypass the B drive! Should we treat the B drive the same as the A drive, or should we continue to bypass it?

Overrides:

getRoots in class javax.swing.filechooser.FileSystemView
