jfilechooser - Java FileFilter to select certain directories -


i trying create filefilter allow user open directory contains file. use case these directories workspaces have file called smart.workspace inside.

currently filter follows...

class smartworkspacefilter extends javax.swing.filechooser.filefilter {      string description = "smart workspace";     string filenamefilter = "smart.workspace";      smartworkspacefilter() {      }      @override     public boolean accept(file file) {          log.debug("testing file: " + file.getname());          if (file.isfile()) {             return false;         }          if (file.isdirectory()) {             file[] files = file.listfiles();             (file f : files) {                  log.debug("directory: " + f.isdirectory());                 log.debug("name: " + f.getname());                  if (f.isdirectory()) {                     return true;                 }                  if (f.getname().equals(filenamefilter)) {                     return true;                 }             }         }         return false;     }      @override     public string getdescription() {         return description;     } }

obviously problem allow user navigate workspace folder have allow sub directories.

for file chooser using option directories_only.

is possible allow user select directory based on directories contents?

for example directory 'workspace' exists @ c://folder1/folder2/wokspace, want allow filechooser 'start' @ c:// , allow user navigate 'workspace' folder , accept it. filechooser shouldn't allow acceptance of folder1 or folder2 still allow navigation through folder1 , folder2.

i dont think can make filefilter differentiate between "files/directories should displayed can accessed" , "files/directories can selected".

a solution problem comes mind is: let user search/select smart.workspace file , navigate there parent folder.

if need dialog described above have involved in detail jfilechooser. extending class gives enough access change behaviour desired.
