Restrict FileSystemView to a Directory

Question

Trying to force my JFileChooser to restrict to only one directory so that users cannot navigate the file system. This custom JFileChooser will be used for playing or deleting files. Any sample code for restricting FileSystemView to a directory, much appreciated.

Answer 1

I'm facing a similar problem i think.
I want to initialize the JfileChooser with selected drives (obtained by a net use command).
I subcalsses the FileSystemView.
In the getRoots() I call the createFileSystemRoot() for each drive I want as root.
(i tried with "new File" or by getting a file from the createFileObject() )
In the getParent(), I check the user doesn't try to go uppser tha, the roots returning the specified root if needed
In the getHome(), I set a directory wich is or is under one of the sp�cified roots.
The result is : the JcomboBox only displays the roots specified, the home button doesn't use the OS root anymore, the level up button is restricted and doen't go outside the roots specified.
The only problem i'm not able to sove :
The JcomboBox is not refresh correctly.
The standard behaviour is :
the combobox displays the curent folder name, when expadning the combo box, it dsiplays all the rrots and expand the hierachy from the root of the current folder to the folder
eg :
root1
folder1
folder2
In my case, the current forlder is correctly displayed in the combo box but when I click on it to expand it, I only see the roots ... not the sub folders as explained in the standard behaviour.
Help is welcome...
