JFileChooser: How to stop autofill file name after clicking on home directory?

This is what I’m talking about:

When you click on the home directory at the top (top red rectangle), it will auto-fill the file name textbox with the home directory absolute path (bottom red rectangle). How do you stop that from auto-filling the textbox?

If possible, if I extend JFileChooser, how do I override that auto-filling in the subclass?
