Mas onde vc ta adicionando os itens na JComboBox?
1 curtida
Acho q vc colocou manualmente, vai em Design, e nas propriedades da JComboBox, tem alguma coisa do tipo: “Selected Index”, vai ter um valor 0, só trocar por -1.
Senão tiver essa opção, tira print das propriedades
1 curtida
fiz isso que você falou, ele tirou as opções.
Manda o print da tela do netbeans aí, das propriedades
1 curtida
tá certo, outra opção é no initComponents vc setar o
suaComboBox.setSelectedItem(null);
ou
suaComboBox.setSelectedIndex(-1);
1 curtida
Obrigado, me desculpa demorar responder estava no banho e jantando, cara tenho outra dúvida, é sobre a mensagem a ser exibida, depois que eu preencher os dados. Eu tenho que exibir a mensagem: " Preencha todos os Campos" , eu usei o JOptionpane, só que o meu programa, tá dando a mesma resposta com os campos totalmente preenchidos. Onde eu terei que mudar, e como limpar esta mensagem ?
if (seuComboBox.getSelectedItem() == null) {
JOptionPane.showMessageDialog(null, "Por favor, selecione algum item");
} else {
//deixa salvar
}
Não é ai não, é no programa em Geral, agora deu certo, obrigado ai .
