下面的示例展示了如何在基于swing的应用程序中创建模态对话框。
使用以下API -
JDialog()- 创建标准对话框。JDialog.getContentPane()- 获取对话框的内容面板。Dialog.ModalityType.DOCUMENT_MODAL- 将对话框显示为模式对话框。
示例
package com.yiibai.swingdemo;
import java.awt.BorderLayout;
import java.awt.Container;
import java.awt.Dialog;
import java.awt.FlowLayout;
import java.awt.LayoutManager;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class SwingTester {
public static void main(String[] args) {
createWindow();
}
private static void createWindow() {
JFrame frame = new JFrame("Swing创建模态对话框");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
createUI(frame);
frame.setSize(560, 200);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
private static void createUI(final JFrame frame){
JPanel panel = new JPanel();
LayoutManager layout = new FlowLayout();
panel.setLayout(layout);
JButton button = new JButton("点击这里开始~");
final JDialog modelDialog = createDialog(frame);
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
modelDialog.setVisible(true);
}
});
panel.add(button);
frame.getContentPane().add(panel, BorderLayout.CENTER);
}
private static JDialog createDialog(final JFrame frame){
final JDialog modelDialog = new JDialog(frame, "Swing创建模态对话框",
Dialog.ModalityType.DOCUMENT_MODAL);
modelDialog.setBounds(132, 132, 300, 200);
Container dialogContainer = modelDialog.getContentPane();
dialogContainer.setLayout(new BorderLayout());
dialogContainer.add(new JLabel("欢迎您学习Java/Swing!")
, BorderLayout.CENTER);
JPanel panel1 = new JPanel();
panel1.setLayout(new FlowLayout());
JButton okButton = new JButton("确定");
okButton.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
modelDialog.setVisible(false);
}
});
panel1.add(okButton);
dialogContainer.add(panel1, BorderLayout.SOUTH);
return modelDialog;
}
}
执行上面示例代码，得到以下结果：
