Java Swing内部框架作为对话框 [英] Java Swing Internal Frame As Dialog

问题描述

我已经在netbeans中创建了一个项目。我有一个内部框架，我想要显示为对话框。请帮帮我。
注意：我已经使用窗口的外观和感觉。

解决方案

不要使用 java.awt.Dialog 或 javax.swing.JDialog 。相反，请查看 JOptionPane 方法以' showInternal .. '开头。 EG

  import java.awt。*; 
 import java.awt.event。*; 
 import javax.swing。*; 
 import javax.swing.border.EmptyBorder; 
 
 public class InternalDialog {
 
 public static void main（String [] args）throws异常{
 Runnable r = new Runnable（）{
 
 @Override 
 public void run（）{
 //用户看到的GUI（无框架）
 JPanel gui = new JPanel（new BorderLayout（））; 
 gui.setBorder（new EmptyBorder（2，3，2，3））; 
 
 JDesktopPane dtp = new JDesktopPane（）; 
 gui.add（dtp）; 
 
 ActionListener listener = new ActionListener（）{
 
 @Override 
 public void actionPerformed（ActionEvent e）{
组件c =（组件）的getSource（）; 
 JOptionPane.showInternalMessageDialog（c，Message）; 
} 
}; 
 for（int ii = 0; ii< 3; ii ++）{
 JInternalFrame jif = new JInternalFrame（）; 
 dtp.add（jif）; 
 jif.setLocation（new Point（ii * 30，ii * 20））; 
 jif.setSize（200,50）; 
 jif.setVisible（true）; 
 
 JButton b =新的JButton（点击我！）; 
 b.addActionListener（listener）; 
 jif.add（b）; 
} 
 
 // TODO！ 
 gui.setPreferredSize（new Dimension（280,150））; 
 gui.setBackground（Color.WHITE）; 
 
 JFrame f = new JFrame（Demo）; 
 f.add（gui）; 
 //确保关闭框架后JVM关闭，
 //所有非守护程序线程完成
 f.setDefaultCloseOperation（JFrame.DISPOSE_ON_CLOSE）; 
 //见http://stackoverflow.com/a/7143398/418556演示。 
 f.setLocationByPlatform（true）; 
 
 //确保框架是最小尺寸，它需要为
 //，以便在其中显示组件
 f.pack（）; 
 //应该最后完成，以避免闪烁，移动，
 //调整大小的工件。 
 f.setVisible（true）; 
} 
}; 
 //应该在EDT 
 // http://docs.oracle.com/javase/tutorial/uiswing/concurrency/initial.html 
 SwingUtilities.invokeLater上创建和更新Swing GUI （R）; 
} 
} 
  

I have created one project in netbeans. I have one internal frame, which I want to be displayed as dialog. Please help me. Note:I have used windows look and feel.

解决方案

Don't use a java.awt.Dialog or javax.swing.JDialog. Instead look to the JOptionPane methods that start with 'showInternal..'. E.G.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.border.EmptyBorder;

public class InternalDialog {

    public static void main(String[] args) throws Exception {
        Runnable r = new Runnable() {

            @Override
            public void run() {
                // the GUI as seen by the user (without frame)
                JPanel gui = new JPanel(new BorderLayout());
                gui.setBorder(new EmptyBorder(2, 3, 2, 3));

                JDesktopPane dtp = new JDesktopPane();
                gui.add(dtp);

                ActionListener listener = new ActionListener() {

                    @Override
                    public void actionPerformed(ActionEvent e) {
                        Component c= (Component)e.getSource();
                        JOptionPane.showInternalMessageDialog(c, "Message");
                    }
                };
                for (int ii=0; ii<3; ii++) {
                    JInternalFrame jif = new JInternalFrame();
                    dtp.add(jif);
                    jif.setLocation(new Point(ii*30, ii*20));
                    jif.setSize(200,50);
                    jif.setVisible(true);

                    JButton b = new JButton("Click me!");
                    b.addActionListener(listener);
                    jif.add(b);
                }

                // TODO!
                gui.setPreferredSize(new Dimension(280, 150));
                gui.setBackground(Color.WHITE);

                JFrame f = new JFrame("Demo");
                f.add(gui);
                // Ensures JVM closes after frame(s) closed and
                // all non-daemon threads are finished
                f.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
                // See http://stackoverflow.com/a/7143398/418556 for demo.
                f.setLocationByPlatform(true);

                // ensures the frame is the minimum size it needs to be
                // in order display the components within it
                f.pack();
                // should be done last, to avoid flickering, moving,
                // resizing artifacts.
                f.setVisible(true);
            }
        };
        // Swing GUIs should be created and updated on the EDT
        // http://docs.oracle.com/javase/tutorial/uiswing/concurrency/initial.html
        SwingUtilities.invokeLater(r);
    }
}
