Olá pessoal.
Estou com problemas no jformattedtextfield. Utilizei o MaskFormatter para limitar a entrada do textfield apenas para um caracter, e que seja apenas número. Na primeira vez, funciona. Mas depois que eu clico no botão LIMPAR, para apagar os números digitados, no textfield pode ser adicionado mais de um número, o que nao pode acontecer. Tem que ser inserido apenas um número.
Alguem tem alguma idéia ?
Segue o código abaixo.
public class Principal {
JFrame frame;
JPanel p, p_btn;
JButton clear;
JTextField t1, t2, t3, t4, t5, t6, t7, t8, t9, t10, t11, t12, t13;
public static void main(String args[]) {
Principal main = new Principal();
main.Componentes();
}
public void Componentes() {
MaskFormatter mask = new MaskFormatter();
try {
mask = new MaskFormatter("#");
} catch(ParseException ex) { }
frame = new JFrame();
p = new JPanel();
t1 = new JTextField("7");
t1.setEditable(false);
t2 = new JTextField("8");
t2.setEditable(false);
t3 = new JTextField("9");
t3.setEditable(false);
t4 = new JFormattedTextField(mask);
t4.setPreferredSize(new Dimension(25, 10));
t5 = new JFormattedTextField(mask);
t5.setPreferredSize(new Dimension(25, 10));
t6 = new JFormattedTextField(mask);
t6.setPreferredSize(new Dimension(25, 10));
t7 = new JFormattedTextField(mask);
t7.setPreferredSize(new Dimension(25, 10));
t8 = new JFormattedTextField(mask);
t8.setPreferredSize(new Dimension(25, 10));

t13.setPreferredSize(new Dimension(25, 10));
t13.setEditable(false);
