JFormattedTextField for paths?

[Hendrik Maryns]

Hi,

I have a GUI which shows a button to select a file on the file system,
with a textfield next to it that then shows the path selected. I want
to ensure, however, that no garbage is input in the text field. The
easy way is of course to make the text field uneditable, such that the
user is forced to use the button and the JFileChooser popping up.
However, it would be nice (I’m a bit Linux-oriented), if one could type
in a file path as well, and this would be validated. Is there a custom
JFormattedTextField available for this? Preferably, it should work on
all platforms, of course.

Cheers, H.

Good question. I did a quick web search. java.io.File will provide
some kind of validation (presumably, specific to the platform on which
you are running) and getCanonicalFile() will make a full localized path
to a file (I think that's what they mean by "canonical").

So I guess no text field, but you should be able to validate it yourself
fairly easily, if the above works.

Aha! And a special verifier for customizing formatted text fields. Very
nice!
