FrameView NetBeans

Olá,

Estou fazendo um projeto para a faculdade, onde tenho que criar telas baseadas em tabelas com as funções de inserir, alterar, deletar, etc.
Encontrei no NetBeans uma solução mais rápida através de um projeto Java Desktop Application, que faz tudo automático a partir da tabela.
Este wizard do NetBeans cria classes que extendem FrameView.

O problema é que tenho que ter uma tela inicial que irá chamar as outras telas.

Gostaria de saber se alguém tem a solução para chamar uma FrameView através de um botão em outra FrameView.

Segue o código da classe FrameView que deverá ser chamada:

public class AlunosView extends FrameView {
    
    public AlunosView(SingleFrameApplication app) {
        super(app);

        initComponents();

        // status bar initialization - message timeout, idle icon and busy animation, etc
        ResourceMap resourceMap = getResourceMap();
        int messageTimeout = resourceMap.getInteger("StatusBar.messageTimeout");
	messageTimer = new Timer(messageTimeout, new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                statusMessageLabel.setText("");
            }
        });
	messageTimer.setRepeats(false);
        int busyAnimationRate = resourceMap.getInteger("StatusBar.busyAnimationRate");
        for (int i = 0; i < busyIcons.length; i++) {
            busyIcons[i] = resourceMap.getIcon("StatusBar.busyIcons[" + i + "]");
        }
        busyIconTimer = new Timer(busyAnimationRate, new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                busyIconIndex = (busyIconIndex + 1) % busyIcons.length;
                statusAnimationLabel.setIcon(busyIcons[busyIconIndex]);
            }
        }); 
        idleIcon = resourceMap.getIcon("StatusBar.idleIcon");
        statusAnimationLabel.setIcon(idleIcon);
        progressBar.setVisible(false);

        // connecting action tasks to status bar via TaskMonitor
        TaskMonitor taskMonitor = new TaskMonitor(getApplication().getContext());
        taskMonitor.addPropertyChangeListener(new java.beans.PropertyChangeListener() {
            public void propertyChange(java.beans.PropertyChangeEvent evt) {
                String propertyName = evt.getPropertyName();
                if ("started".equals(propertyName)) {
                    if (!busyIconTimer.isRunning()) {
                        statusAnimationLabel.setIcon(busyIcons[0]);
                        busyIconIndex = 0;
                        busyIconTimer.start();
                    }
                    progressBar.setVisible(true);
                    progressBar.setIndeterminate(true);
                } else if ("done".equals(propertyName)) {
                    busyIconTimer.stop();
                    statusAnimationLabel.setIcon(idleIcon);
                    progressBar.setVisible(false);
                    progressBar.setValue(0);
                } else if ("message".equals(propertyName)) {
                    String text = (String)(evt.getNewValue());
                    statusMessageLabel.setText((text == null) ? "" : text);
                    messageTimer.restart();
                } else if ("progress".equals(propertyName)) {
                    int value = (Integer)(evt.getNewValue());
                    progressBar.setVisible(true);
                    progressBar.setIndeterminate(false);
                    progressBar.setValue(value);
                }
            }
        });

Vc esta utilizando o Netbeans isso???

Tem que criar um novo JFrame!!!

Depois adiciona um JmenuBar = Barra de Menu

Em seguida vc adiciona no Jmenubar um Jmenuitem = Item de menu!!!
Pra chamar o outro formulário vc clica com o botão direito do mouse em cima o Item de menu, Vá em eventos - > action - > actionPerformed

Pra chamar o Jpane!!

Insira o codigo

private void menu_Aluno(java.awt.event.ActionEvent evt) {                                                 
      AlunosView alunosView = new AlunosView(this, true);
      alunosView.show(true);
    }

Veja se funciona!!!

Estou utilizando o NetBeans sim!

Não funciona pq o contrutor da classe AlunosView pede um SingleFrameApplication como parâmetro.

E a classe AlunosView não tem o método ‘show’.

Como você chama esta classe atualmente?
Ela não vem do nada e, se você tentar executar pelo shift + F6 ele dará erro, correto?
Deve existir uma outra classe, dentro deste projeto, que possua uma chamada satisfatória.
Embora eu acredite que

private void menu_Aluno(java.awt.event.ActionEvent evt) {                                                   
     AlunosView alunosView = new AlunosView(new SingleFrameApplication());  
   }

deve funcionar

Tem esta classe AlunosApp que o NetBeans cria também.
Essa sim executa pelo shift + F6.
Mas preciso que ela seja executada apartir de um botão em outro FrameView.

/*
 * AlunosApp.java
 */

package alunos;

import org.jdesktop.application.Application;
import org.jdesktop.application.SingleFrameApplication;

/**
 * The main class of the application.
 */
public class AlunosApp extends SingleFrameApplication {

    /**
     * At startup create and show the main frame of the application.
     */
    @Override public void startup() {
        show(new AlunosView(this));
    }

    /**
     * This method is to initialize the specified window by injecting resources.
     * Windows shown in our application come fully initialized from the GUI
     * builder, so this additional configuration is not needed.
     */
    @Override protected void configureWindow(java.awt.Window root) {
    }

    /**
     * A convenient static getter for the application instance.
     * @return the instance of AlunosApp
     */
    public static AlunosApp getApplication() {
        return Application.getInstance(AlunosApp.class);
    }

    /**
     * Main method launching the application.
     */
    public static void main(String[] args) {
        launch(AlunosApp.class, args);
    }
}
