我使用各种类对项目进行编码,但是当我按下一个调用我的主菜单的按钮时我卡住了,这是我恢复的代码:
我的主要课程:
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
Dimension res = Toolkit.getDefaultToolkit().getScreenSize();
public void run(){
Principal frame = new Principal("Program");
frame.setSize(res.width,res.height);
frame.setResizable(false);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setUndecorated(true);
frame.setVisible(true);
}
});`
现在,我的校长:
public class Principal extends JFrame implements ActionListener {
private DetallesPrincipal DetallesPrincipal;
private ClientesNuevo ClientesNuevo;
private ClientesModificar ClientesModificar;
Container p;
private static final long serialVersionUID = 1L;
final JMenuItem Clientes1,Clientes2,Clientes3;
final JMenuBar MenuBarMain = new JMenuBar();
public Principal (String titulo){
super(titulo);
setLayout(new BorderLayout());
final JMenuBar MenuBarMain = new JMenuBar();
MenuBarMain.setBackground(new Color(177,178,182));
final JMenu MenuMainClientes;
MenuMainClientes = new JMenu("Clientes");
DetallesPrincipal = new DetallesPrincipal();
ClientesNuevo = new ClientesNuevo();
p = getContentPane();
MenuBarMain.add(MenuMainClientes);
Clientes1 = new JMenuItem("Nueva ficha");
MenuMainClientes.add(Clientes1);
Clientes1.addActionListener(this);
p.add(MenuBarMain, BorderLayout.PAGE_START);
p.add(DetallesPrincipal, BorderLayout.CENTER);
}
@Override
public void actionPerformed(ActionEvent e) {
if (e.getSource()==Clientes1){
p.removeAll();
p.repaint();
p.add(ClientesNuevo, BorderLayout.CENTER);
p.revalidate();
p.repaint();
}
我的客户新:
public class ClientesNuevo extends JPanel implements ActionListener {
private static final long serialVersionUID = 1L;
DetallesPrincipal m;
GridBagConstraints gc = new GridBagConstraints();
public ClientesNuevo() {
Dimension size = getPreferredSize();
size.width = 250;
setPreferredSize(size);
setBackground(new Color(111,114,123));
TitledBorder Principal2 = BorderFactory.createTitledBorder("Te encuentras en clientes");
Principal2.setTitleColor(new Color(100,100,100));
Principal2.setTitleFont(new Font("Arial",0,24));
Principal2.setTitlePosition(TitledBorder.BOTTOM);
Principal2.setTitleJustification(TitledBorder.LEFT);
setBorder(Principal2);
JLabel Titulo1 = new JLabel("Nueva ficha cliente");
Titulo1.setFont(new Font("Tahoma",0,36));
JLabel Nombre = new JLabel("Nombre/Razón social ");
JLabel Apellidos = new JLabel("Apellidos ");
JLabel Cif = new JLabel("CIF/DNI ");
JLabel Poblacion = new JLabel("Población ");
JLabel Provincia = new JLabel("Provincia");
JLabel Cpostal = new JLabel("Código postal");
JLabel Telefono = new JLabel("Teléfono");
JLabel Movil = new JLabel("Móvil");
JLabel Notas = new JLabel("Notas");
JTextField NombreText = new JTextField(25);
JTextField ApellidosText = new JTextField(25);
JTextField CifText = new JTextField(15);
JTextField PoblacionText = new JTextField(15);
JTextField ProvinciaText = new JTextField(20);
JTextField CpostalText = new JTextField(15);
JTextField TelefonoText = new JTextField(20);
JTextField MovilText = new JTextField(20);
JTextField NotasText = new JTextField(30);
JButton Aceptar = new JButton("Aceptar");
JButton Cancelar = new JButton("Cancelar");
Aceptar.addActionListener(this);
setLayout(new GridBagLayout());
GridBagConstraints gc = new GridBagConstraints();
gc.gridx = 0;
gc.gridy = 0;
gc.weighty = 1;
add(Titulo1, gc);
gc.anchor = GridBagConstraints.LINE_START;
gc.gridx = 0;
gc.gridy = 1;
add(Nombre, gc);
gc.gridx = 1;
gc.gridy = 1;
add(NombreText, gc);
gc.gridx = 0;
gc.gridy = 2;
add(Apellidos, gc);
gc.anchor = GridBagConstraints.LINE_START;
gc.gridx = 1;
gc.gridy = 2;
add(ApellidosText, gc);
gc.anchor = GridBagConstraints.LINE_START;
gc.weightx = 1;
gc.weighty = 1;
gc.gridx = 0;
gc.gridy = 3;
add(Cif, gc);
gc.anchor = GridBagConstraints.LINE_START;
gc.gridx = 1;
gc.gridy = 3;
add(CifText, gc);
gc.gridx = 0;
gc.gridy = 4;
add(Poblacion, gc);
gc.gridx = 1;
gc.gridy = 4;
add(PoblacionText, gc);
gc.gridx = 2;
gc.gridy = 4;
add(Provincia, gc);
gc.gridx = 2;
gc.gridy = 7;
add(Aceptar, gc);
gc.gridx = 3;
gc.gridy = 7;
add(Cancelar, gc);
}
public void actionPerformed(ActionEvent e) {
removeAll();
repaint();
m = new DetallesPrincipal();
add(m,gc);
revalidate();
repaint();
}
}
好吧,对不起那个墙,但我很迷茫,我只想调用我的 DetallesPrincipal 类的组件,管理这样的程序的更好选择是什么?
