Question

java中,我要在一个程序里加什么代码,才能使得我在这个程序里单击按钮后打开另外一个我已经编写好的窗口???

简单的说就是,一个程序的按钮一按,就弹出另外一个我已经做好的新窗口

Answer 1

Button b=new Button(shell,SWT.NONE);

b..addSelectionListener(new SelectionAdapter() {
public void widgetSelected(final SelectionEvent e) {
OTHERSHELL os=new OTHERSHELL(shell);
os.open();
}
});

Answer 2

加一个按钮 Button b=new Button();
然后这个按钮加一个监听器,监听器里面实现监听器的方法接口.接口里面就new你已经编写好的窗口.

import java.awt.Container;
import java.awt.FlowLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;

public class Test extends JFrame {
public Test() {
Container c = getContentPane();
c.setLayout(new FlowLayout());
JLabel jl = new JLabel("我是A");
JButton jb = new JButton("我是A--C");
c.add(jb);
c.add(jl);
setSize(300, 300);
setVisible(true);
jb.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
bb b = new bb();
b.setSize(200, 200);
b.setVisible(true);
dispose();
}
});
}

public static void main(String[] args) {
Test s = new Test();
s.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

class bb extends JFrame {
public bb() {
Container c = getContentPane();
c.setLayout(new FlowLayout());
JLabel jl = new JLabel("我是B");
JButton jb = new JButton("我是B--C");
c.add(jb);
c.add(jl);
jb.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
Test b = new Test();
b.setSize(300, 300);
b.setVisible(true);
dispose();
}
});
}
}
}
