Hi,

I got a problem to create a special mask for a JFormattedTextField. I
got the follwing code:

    mask = new MaskFormatter();
    mask.setValidCharacters("0123456789.");
    try
    {
      mask.setMask("???#");
    }
    catch (ParseException ex1)
    {
    }

    component = new JFormattedTextField(mask);

But this is not how it should work. I want to build in the following
restriction for the characters:

* Maximum of characters is 4
* First character must be a digit or a dot
* Second character must be a digit if the first character is a dot.
Otherwise it may be a digit or a dot.
* Third character must be a digit if the second character is a dot.
Otherwise it may be a digit or a dot.
* Forth character must be a digit
* When a dot is used, there may only be one character putted in after
it and must be a 5
* The value in this JFormattedTextField may variate from empty to
9999, which means that the value can contain 1, 2, 3 or 4 characters.

Is it possible to set restrictions for just one charcater, so that I
can build in above mentioned restrictions?

I hope someone can help me out here,

thnx in advance
Rogier
