Pan*_*apa 7 java swing jframe jdialog jwindow
我正在为我的笔记本电脑开发一个工具.我想在JFrame中禁用最小化按钮.我已经禁用了最大化和关闭按钮.
以下是禁用最大化和关闭按钮的代码:
JFrame frame = new JFrame();
frame.setResizable(false); //Disable the Resize Button
// Disable the Close button
frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);

请告诉我如何禁用最小化按钮.
正如@MadProgrammer所说(给他+1),这绝对不是你想要的好主意
使用a JDialog并调用setDefaultCloseOperation(JDialog.DO_NOTHING_ON_CLOSE);以确保无法关闭.
您也可以使用JWindow(+1到@MM)或调用setUndecorated(true);您的JFrame实例.
或者,您可能希望通过在方法中覆盖和调用来添加自己WindowAdapater的JFrame非最小化等: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
public void windowClosing(WindowEvent we) {//overrode to show message
super.windowClosing(we);
JOptionPane.showMessageDialog(frame, "Cant Exit");
}
@Override
public void windowIconified(WindowEvent we) {
frame.setState(JFrame.NORMAL);
JOptionPane.showMessageDialog(frame, "Cant Minimize");
}
};
}
}
