I would like to "clear" a JFormattedTextField programmatically but if I simply call txtAny.setText("") it is doesn't work cause textfield's regex pattern in my case:

private final String FORMATTER_STRING_FLOAT =
 "[\\p{Digit}\\p{Cntrl}]{1,32}(\\.[\\p{Digit}\\p{Cntrl}]{0,2})?";
that requires at least one digit.

So my question is: how can I obtain a regex pattern of a JFormattedTextField for at least further manual partial processing?

  • should be simple and possible, there isn't reason be confused thread linked by @DNA, depends of your code in the [SSCCE](http://sscce.org/) form – mKorbel Feb 23 '12 at 11:43

Call setText(anyValidString) rather than setText("")
