正如@MadProgrammer 所说(对他+1),这绝对不是你想要的好主意
或者,您可能希望通过在方法中覆盖和调用来添加自己的WindowAdapater
以使JFrame
不可最小化等:windowIconified(..)
setState(JFrame.NORMAL);
//necessary imports
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
public class Test {
/**
* Default constructor for Test.class
*/
public Test() {
initComponents();
}
public static void main(String[] args) {
/**
* Create GUI and components on Event-Dispatch-Thread
*/
javax.swing.SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
Test test = new Test();
}
});
}
private final JFrame frame = new JFrame();
/**
* Initialize GUI and components (including ActionListeners etc)
*/
private void initComponents() {
frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
frame.setResizable(false);
frame.addWindowListener(getWindowAdapter());
//pack frame (size JFrame to match preferred sizes of added components and set visible
frame.pack();
frame.setVisible(true);
}
private WindowAdapter getWindowAdapter() {
return new WindowAdapter() {
@Override

}

frame.setState(JFrame.NORMAL);
JOptionPane.showMessageDialog(frame, "Cant Minimize");
