实际上我创建了一个Swing GUI，它有两个按钮（galaxy和iPhone），我创建了2个 java class 来手动设计表，当我使用 new iPhoneTable（）时。 setVisible（true）对于那个按钮我没有得到答案，另一方面我试图将该按钮与另一个摆动GUI连接并且它正常工作。
这是我的主要程序，我拿了重要的代码。
public class MainFrame7 extends javax.swing.JFrame {
iPhoneTable iPheezy = new iPhoneTable();
GalaxyTable galxy = new GalaxyTable();
public MainFrame7() {
initComponents();}
private void jButton4ActionPerformed(java.awt.event.ActionEvent evt) {
iPheezy.setVisible(true);
}
答案 0 :(得分：0)
尝试并运行此示例。我有三节课。主要的一个，iPhone和Galaxy类。我在主GUI中创建了iPhone和Galaxy的对象，按钮将其可见性设置为true
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
public class Test10 extends JPanel {
JButton galaxy = new JButton("Galaxy");
JButton iPhone = new JButton("iPhone");
iPhone iPheezy = new iPhone();
Galaxy galxy = new Galaxy();
public Test10() {
add(galaxy);
add(iPhone);
galaxy.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
galxy.setVisible(true);
}
});
iPhone.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
iPheezy.setVisible(true);
}
});
}
public static void createAndShowGui() {
JFrame frame = new JFrame();
frame.add(new Test10());
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLocationRelativeTo(null);
frame.pack();
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGui();
}
});
}
}
class iPhone extends JFrame {
public iPhone() {
setSize(300, 300);
setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);
setLocationByPlatform(true);
}
}
class Galaxy extends JFrame {
public Galaxy() {
setSize(300, 300);
setDefaultCloseOperation(JFrame.HIDE_ON_CLOSE);
setLocationByPlatform(true);
}
}
修改： 你的代码什么都不做。
public void actionPerformed() 编辑2：我的GUI Builder中的完整代码。工作正常
import javax.swing.JFrame;
public class MainFrame7 extends javax.swing.JFrame {
iPhone iPheezy = new iPhone();
Galaxy galxy = new Galaxy();
public MainFrame7() {
initComponents();
}
