Problemas com JFormattedTextField

Boa noite, amigos

Com a ajuda dos colegas do GUJ, consegui “mascarar” um campo de texto. Vejam meu código:

jTValor = new javax.swing.JFormattedTextField(); try { ftmValor = new MaskFormatter("###,##"); } catch (ParseException ex) { JOptionPane.showMessageDialog(null, "Digite apenas números. Não digite . ou ,"); } jTValor = new JFormattedTextField(ftmValor); ftmValor.setValidCharacters("[telefone removido]"); add(jTValor); jTValor.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(java.awt.event.ActionEvent evt) { jTValorActionPerformed(evt); } });
Minha dúvida é: se eu deixar o MaskFormatter do jeito que está (###,##) só consigo colocar valores tipo 100, 200, 300 etc. Não conseguirei colocar 1,00 ou 10,00. Como eu posso alterar o MaskFormatter para aceitar qualquer valor, mantendo as duas casas decimais?

Um abraço.

Não sei se existe algo pronto, mas você pode utilizar um inputVerifier. Por exemplo:

class FormattedTextFieldVerifier extends InputVerifier {
	static DecimalFormat df = new DecimalFormat("###.00", new DecimalFormatSymbols(new Locale("pt","br")));
	
    public boolean verify(JComponent input) {
        if (input instanceof JFormattedTextField) {
            JFormattedTextField ftf = (JFormattedTextField)input;
            AbstractFormatter formatter = ftf.getFormatter();
            if (formatter != null) {
                String text = ftf.getText();
                if ( !text.endsWith(",00" )) {
                	int indice = text.indexOf(",");
                	String tmp = text.substring(indice, text.length());
                	tmp = tmp.replaceAll(" ", "0");
                	text = text.substring(0, indice) + tmp;
                }
            	try {
					df.parse(text);
                	ftf.setText(text);
				} catch (ParseException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
					JOptionPane.showMessageDialog(null, "Valor inválido!");
					return false;
				}
            }
         }
         return true;
     }
     public boolean shouldYieldFocus(JComponent input) {
         return verify(input);
     }
 }

e no objeto JFormattedTextField você chama o método setInputVerifier:

MaskFormatter fmtValor = new MaskFormatter("###,##");
JFormattedTextField tf = new JFormattedTextField(  fmtValor );
fmtValor.setValidCharacters("[telefone removido]");                  
tf.setInputVerifier(new FormattedTextFieldVerifier());

Essa classe te dá uma idéia do que pode ser feito, porém o método verify deve ser alterado
dependendo do tipo de formatação/validação. No exemplo ele vai validar desde que você coloque os três
primeiros números. Neste caso ele completa com “00” no final.

Até mais.

Bom dia,

Testei o código do colega acima, e deu o seguinte erro:

Voltando ao problema, testei no NetBeans, e o valor é formatado corretamente. Só que fui visualizar os registros no banco de dados, e o campo valor está em branco. O estranho é que é um campo não nulo, as outras informações foram salvas normalmente.

Por que será, já que não me aparece nenhuma mensagem de erro?

O tipo de campo valor no banco é VARCHAR, e meu código ficou:

jTValor = new javax.swing.JFormattedTextField(); DecimalFormat df = new DecimalFormat("###.00", new DecimalFormatSymbols(new Locale("pt","br"))); JFormattedTextField jTValor = new JFormattedTextField(new NumberFormatter(df)); jTValor.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(java.awt.event.ActionEvent evt) { jTValorActionPerformed(evt); } });
