Boa tarde galera sou iniciante no java e me deparei com um problema que não faço ideia do que seja
possuo uma Frame que ao clicar em um botão começa a rodar um processo ao fazer isso eu quero
abrir outra janela para que mostre carregando a janela esta pronta o problema é que quando chamo
a outra tela dentro do evento do botão ela aparece em branco sem os componentes internos neste caso
seriam duas jlabels.
O evento do botao seria:
private void jButtonImportarActionPerformed(java.awt.event.ActionEvent evt) {
Importe importe = new Importe();
JFrameCarregando carregandoJFrame = new JFrameCarregando();
if (!(diretorio == null)) {
try {
this.setVisible(false);
carregandoJFrame.setVisible(true);
importe.lerArquivo(diretorio);
} catch (Exception ex) {
ex.printStackTrace();
}
} else {
JOptionPane.showMessageDialog(rootPane, "Arquivo não Selecionado");
}
carregandoJFrame.setVisible(false);
this.setVisible(true);
}
ja a outra tela seria:
import javax.swing.ImageIcon;
/**

public class JFrameCarregando extends javax.swing.JFrame {
/**

public JFrameCarregando() {
