本文介绍了Java Swing内部框架作为对话框的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
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);
}
}
