Java Swing实现的定制TextField功能示例

Java Swing实现的定制TextField功能示例

本文实例讲述了java Swing实现的定制TextField功能。分享给大家供大家参考，具体如下：

先来看看运行效果：

具体代码如下：

package themedemo;

import java.awt.BasicStroke;

import java.awt.BorderLayout;

import java.awt.Color;

import java.awt.Graphics2D;

import java.awt.GridLayout;

import java.awt.Insets;

import java.awt.RenderingHints;

import java.util.Map;

import javax.swing.BorderFactory;

import javax.swing.JComponent;

import javax.swing.JFrame;

import javax.swing.JPanel;

import javax.swing.JTextField;

import javax.swing.Painter;

import javax.swing.SwingUtilities;

import javax.swing.UIDefaults;

import javax.swing.UIManager;

import javax.swing.WindowConstants;

public class TextFieldSkinDemo {

public static void main(String[] args) {

SwingUtilities.invokeLater(new Runnable() {

public void run() {

for (UIManager.LookAndFeelInfo laf : UIManager

.getInstalledLookAndFeels()) {

if ("Nimbus".equals(laf.getName())) {

try {

UIManager.setLookAndFeel(laf.getClassName());

} catch (Exception e) {

e.printStackTrace();

}

}

}

for (Map.Entry

.getLookAndFeelDefaults().entrySet()) {

if ((entry.getKey().toString()).startsWith("TextField")) {

System.out.println(entry.getKey() + " = "

+ entry.getValue());

}

}

JFrame frame = new JFrame("jb51.net - TextField Skining Demo");

frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

frame.getContentPane().setLayout(new BorderLayout());

JPanel panel = new JPanel(new GridLayout(0, 1, 20, 20));

panel.setBorder(BorderFactory.createEmptyBorder(20, 20, 20, 20));

panel.setBackground(Color.darkGray);

UIDefaults textFieldDefaults = new UIDefaults();

textFieldDefaults.put("TextField.contentMargins", new Insets(6,

6, 6, 6));

textFieldDefaults.put("TextField[Selected].textForeground",

Color.WHITE);

textFieldDefaults.put("TextField.backgroundPainter",

new Painter() {

public void paint(Graphics2D g, JComponent c,

int w, int h) {

g.setRenderingHint(

RenderingHints.KEY_ANTIALIASING,

RenderingHints.VALUE_ANTIALIAS_ON);

g.setStroke(new BasicStroke(2f));

g.setColor(Color.WHITE);

g.fillRoundRect(0, 0, w - 2, h - 2, 8, 8);

}

});

textFieldDefaults.put("TextField.borderPainter",

new Painter() {

public void paint(Graphics2D g, JComponent c,

int w, int h) {

g.setRenderingHint(

RenderingHints.KEY_ANTIALIASING,

RenderingHints.VALUE_ANTIALIAS_ON);

g.setStroke(new BasicStroke(2f));

g.setColor(Color.LIGHT_GRAY);

g.drhttp://awRoundRect(0, 0, w - 2, h - 2, 8, 8);

}

});

JTextField textField = new JTextField(15);

panel.add(textField);

textField.putClientProperty("Nimbus.Overrides",

textFieldDefaults);

textField.putClientProperty("Nimbus.Overrides.InheritDefaults",

false);

// Add a normal themed slider for comparison

JTextField normalTextField = new JTextField(15);

panel.add(normalTextField);

frame.getContentPane().add(panel, BorderLayout.CENTER);

frame.pack();

frame.setLocationRelativeTo(null);

frame.setVisible(true);

}

});

}

}
