javase实现jframe中通过按钮关闭其它jframe窗体

发布时间：2017-10-01 16:15:09编辑：雪饮阅读（）

有这样的一个需求：

需要在一个jframe中去关闭另外一个jframe的窗体。

下面test1为入口的jframe，该jframe中将有一个按钮，点击该按钮就可以关闭另外一个test2的jframe窗体。

 

test1源码：

package test;

import java.awt.BorderLayout;

import javax.swing.JPanel;

import javax.swing.JFrame;

import javax.swing.JLabel;

public class test1 extends JFrame {

    private static final long serialVersionUID = 1L;

    private JPanel jContentPane = null;

    private JLabel jLabel = null;

    public test1() {

       super();

       initialize();

    }

    private void initialize() {

       this.setSize(300, 200);

       this.setContentPane(getJContentPane());

       this.setTitle("JFrame");

    }

    private JPanel getJContentPane() {

       if (jContentPane == null) {

           jLabel = new JLabel();

           jLabel.setText("我是test1窗体");

           jContentPane = new JPanel();

           jContentPane.setLayout(new BorderLayout());

           jContentPane.add(jLabel, BorderLayout.NORTH);

       }

       return jContentPane;

    }

}

 

test2源码：

package test;

import javax.swing.SwingUtilities;

import java.awt.BorderLayout;

import javax.swing.JPanel;

import javax.swing.JFrame;

import javax.swing.JButton;

public class test2 extends JFrame {

    private static final long serialVersionUID = 1L;

    private static test1 test1Obj;

    private JPanel jContentPane = null;

    private JButton jButton = null;

    private JButton getJButton() {

       if (jButton == null) {

           jButton = new JButton();

           jButton.setText("点击我就可以关闭TEST1窗口");

           jButton.addActionListener(new java.awt.event.ActionListener() {

              public void actionPerformed(java.awt.event.ActionEvent e) {

                  //关闭test1窗体的方法

                  test1Obj.dispose();

              }

           });

       }

       return jButton;

    }

    public static void main(String[] args) {

       SwingUtilities.invokeLater(new Runnable() {

           public void run() {

              test2 thisClass = new test2();

              thisClass.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

              thisClass.setVisible(true);

           }

       });

    }

    public test2() {

       super();

       test1Obj=new test1();

       test1Obj.setVisible(true);

       initialize();

    }

    private void initialize() {

       this.setSize(300, 200);

       this.setContentPane(getJContentPane());

       this.setTitle("JFrame");

    }

    private JPanel getJContentPane() {

       if (jContentPane == null) {

           jContentPane = new JPanel();

           jContentPane.setLayout(new BorderLayout());

           jContentPane.add(getJButton(), BorderLayout.NORTH);

       }

       return jContentPane;

    }

}
