How to filter files without extensions using file dialog in Java

Question

In my application I need to select files with out file extension using file dialog. Is there a way to achieve this? Please help me to find a solution for this. My current code with out any filter is given below:

@Override
            public void handleEvent(Event event) {

                FileDialog dialog = new FileDialog(shell, SWT.NONE);
                String filePath = dialog.open();
                if (filePath != null && !filePath.equals("")) {
                    //Do my Operations

                }

            }

when the dialog is shown up to select a file, you need to display only the file which are without any extensions (means flat files) ? Am i rite? — AJJ, Dec 20 '13 at 10:02

Hi GGrec,Thanks for the replay.I read the link shared by you.It only says how to filter files with extensions. I want to filter files without extensions. — EJoe, Dec 20 '13 at 10:30
@EJoe it cannot be done. You can not filter and show only the files without extension. You can filter and show only files with extension. See http://superuser.com/questions/691083/view-only-files-without-extension-in-file-choose-windows-7/691094?noredirect=1#691094 — AJJ, Dec 20 '13 at 11:42

FileNameExtensionFilter class won't allow you to filter with empty extensions. So, create your own FileFilter.

FileFilter filterWithoutExtension = new FileFilter() {

        @Override
        public boolean accept(File f) {
            // This will display only the files without "."
            return !f.getName().contains(".");
        }

        @Override
        public String getDescription() {
            return "Files Without Extension";
        }
};

Then set this one as your FileFilter.

myFileChooser.setFileFilter(filterWithoutExtension);

Is there any way to achieve this using FileDialog.Is it possible to create my own FileFilter and use it with fileDialog?. — EJoe, Dec 23 '13 at 13:08
