Galera, é o seguinte, eu to querendo colocar tipo uma janela com opções dentro do meu JFrame. Tipo, eu vou no menu da janela e clico em uma opção e ela insere na janela principal uma lista de opções. Já tentei de tudo que eu to lembrado mas sempre usando o setvisible(true) as opções só aparecem em uma nova janela. O código do frame principal tá aí:
public class frmGerenciarConta extends javax.swing.JFrame {
/** Creates new form frmGerenciarConta */
public frmGerenciarConta() {
initComponents();
}
/** This method is called from within the constructor to
* initialize the form.
* WARNING: Do NOT modify this code. The content of this method is
* always regenerated by the Form Editor.
