Open source Java filechooser supporting automatic file name extension?

Is there a good open source filechooser for java that supports automatic file name extension?

What I want is a filechooser that acts similar to office programs' when saving files; that is, a filechooser which has the option of automatically saving a file with one of a few predefined file extensions. The file name extension should be one those available to choose from in the file 开发者_开发技巧filters usually found below the input-field.

The filechooser must also support linux operating systems.

I used this solution instead: adjust selected File to FileFilter in a JFileChooser

Try XFileDialogue.
