Boa Tarde galera sou novo no java e novo no fórum estou com o seguinte problema
em um determinado momento na minha aplicação dentro de uma janela aciono um botão
o evento deste botão seria chamar outra tela, ele chama a tela no entanto ela vem sem seus
componentes apenas aparece em branco.
Código do evento do botão:
private void jButtonImportarActionPerformed(java.awt.event.ActionEvent evt) {
Importe importe = new Importe();
//nova janela que irá abrir com o evento do botão
JFrameCarregando carregandoJFrame = new JFrameCarregando();
if (!(diretorio == null)) {
try {
this.setVisible(false);
carregandoJFrame.setVisible(true);
//importe apenas um evento executado também ao se apertar o botão
importe.lerArquivo(diretorio);
} catch (Exception ex) {
ex.printStackTrace();
}
} else {
JOptionPane.showMessageDialog(rootPane, "Arquivo não Selecionado");
}
carregandoJFrame.setVisible(false);
this.setVisible(true);
}
O código da Janela que deveria ser aberta segue:
public class JFrameCarregando extends javax.swing.JFrame {
/**
* Creates new form JFrameCarregando
*/
public JFrameCarregando() {
initComponents();
setLocationRelativeTo(null);
}
/**
* This method is called from within the constructor to initialize the form.
