public class FilteredJTextField
extends javax.swing.JTextField

Class FilteredJTextField is an extension of 'JTextField' which only allows certain characters to be entered into it. Static strings of allowed characters for numeric types (i.e. INTEGER_CHARS) are provided. To construct a text field that only allows valid floating point numeric values (including the 'e' exponent) to be entered, the following constructor could be used: new FilteredJTextField("",5,SIGNED_EFLOAT_CHARS,true) It will initially be empty and have a column size of 5. The 'true' flag indicates that only valid numeric values are allowed, so numeric rules (such as only one decimal point, etc) are applied.
