Arquivo Discussoes de Programacao e Tecnologia Olá galera, fiz uma aplicação ak, com varias abas(painel) aba cliente, aba fornecedor, na aba cliente eu cadastro os cliente blz.
ja a aba fornecedor eu quero recuperar o cliente cadastrado sem usar botão, quero digitar o CNPJ e recuperar o dados dos clientes apenas com a tecla enter.
ai valeoo
abrazzz
implemente um keylistener para o field onde vc quer executar a operaçao
Oi,
ou então você poderia implementar o FocusListener no campo textfield utilizando
o método focusLost. Assim que o usuario terminar de digitar o CNPJ e mudar de campo,
seja ela com o mouse ou com a tecla tab do teclado, irá carregar as informações do usuário.
Tchauzin!
Isto é muito mais fácil. Pegue todos os componentes que precisam que o ENTER funcione como TAB, e chame este método sobre eles:
/**
* Este método faz com que o ENTER seja considerado como TAB, em componentes como
* um JTextField.
* @param comp O componente.
*/
public static void considerarEnterComoTab (Component comp) {
Set<AWTKeyStroke> keystrokes = comp.getFocusTraversalKeys(KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS);
Set<AWTKeyStroke> newKeystrokes = new HashSet<AWTKeyStroke> (keystrokes);
newKeystrokes.add (AWTKeyStroke.getAWTKeyStroke(KeyEvent.VK_ENTER, 0));
comp.setFocusTraversalKeys (KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS, newKeystrokes);
}

thingol, por favor me salve, ainda coloco o considerarEnterComoTab(txtNome), o meu projeto ja ta pronto, aonde adiciono o codigo e no botão como fazer e ele passaé o codigo.
