These Threee Classes are what I got so far.

What I want is 'searching a file' function on the right side of path textfield.

The location of search textfield is fine now, but i have no clue how to add function on it.

It should show a file that contains a word which the user type on search text field. (The file that is in current directory ONLY. Don't need to show a file in subdirectory)

And when the search textfield is blank, it should show all the files in current directory as usual.

Please help me on this.
