public class FloatingPointTextField extends JTextField
A simple text field for inputing floating point numbers. The field is continuously validated so that only valid characters and values can be entered. If the text is blank or contains only "-", ".", or "-.", the value is considered to be 0. You can optionally set a min and max value. In order for the continuous validation to work, the max must be a non-negative number and the min must be a non-positive number.
