There is no way in the current API to change the filter field on the file dialog.

The description field as copied from bug report 1228900 follows:

I implemented the action method for FilenameFilter. Calling FileDialog.setFilenameFilter()
seems to have no affect. I searched around in the code and I think that this is not
implemented, but I could be wrong.

The description field as copied from bug report 1230302 follows:

getFilenameFilter always returns null though the filter displays an entry.

setFilenameFilter doesnt set the filter and call 'accept' in the FilenameFilter class
to determine the right files matching the filter.

To reproduce, run the test FileDialogTest.java in the testsuite (awt) directory.

Subject: Filtering file directory

I have been trying to use the setFilenameFilter method in the FileDialog
class, but I haven't been able to get it to do anything. I set up a class of
FilenameFilter whose method accept returns true for the file extensions I
want and false for those I don't want, but this method never seems to get
called (I put in a System.out.println statement to make sure) and the
directory continues to show all file names. Have you implemented this
feature? If so, how do I make it work?
