[code]
1.首先自己扩展一个TitledBorder ，源码如下：
public class ComponentTitledBorder implements Border, MouseListener,
SwingConstants {
int offset = 5;
Component comp;
JComponent container;
Rectangle rect;
Border border;
public ComponentTitledBorder(Component comp, JComponent container,
Border border) {
this.comp = comp;
this.container = container;
this.border = border;
container.addMouseListener(this);
}
public boolean isBorderOpaque() {
return true;
}
public void paintBorder(Component c, Graphics g, int x, int y, int width,
int height) {
Insets borderInsets = border.getBorderInsets(c);
Insets insets = getBorderInsets(c);
int temp = (insets.top - borderInsets.top) / 2;
border.paintBorder(c, g, x, y + temp, width, height - temp);
Dimension size = comp.getPreferredSize();
rect = new Rectangle(offset, 0, size.width, size.height);
SwingUtilities.paintComponent(g, comp, (Container) c, rect);
}
public Insets getBorderInsets(Component c) {
Dimension size = comp.getPreferredSize();
Insets insets = border.getBorderInsets(c);
insets.top = Math.max(insets.top, size.height);
return insets;
}
private void dispatchEvent(MouseEvent me) {
if (rect != null && rect.contains(me.getX(), me.getY())) {
Point pt = me.getPoint();
pt.translate(-offset, 0);
comp.setBounds(rect);
comp.dispatchEvent(new MouseEvent(comp, me.getID(), me.getWhen(),
me.getModifiers(), pt.x, pt.y, me.getClickCount(), me
.isPopupTrigger(), me.getButton()));
if (!comp.isValid())
container.repaint();
}
}
public void mouseClicked(MouseEvent me) {
dispatchEvent(me);
}
public void mouseEntered(MouseEvent me) {
dispatchEvent(me);
}
public void mouseExited(MouseEvent me) {
dispatchEvent(me);
}
public void mousePressed(MouseEvent me) {
dispatchEvent(me);
}
public void mouseReleased(MouseEvent me) {
dispatchEvent(me);
}
}
2.测试运行，测试代码如下
public class MyBorder {
public static void main(String[] args) {
try{
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch(Exception e){
e.printStackTrace();
}
final JPanel proxyPanel = new JPanel();
proxyPanel.add(new JLabel("google: "));
proxyPanel.add(new JTextField("www.google.com.hk"));
proxyPanel.add(new JLabel("google Port"));
proxyPanel.add(new JTextField("8080"));
final JCheckBox checkBox = new JCheckBox("测试标题带Checkbox的TitledBorder", true);
final JRadioButton radio = new JRadioButton("测试标题带Radio的TitledBorder", true);
checkBox.setFocusPainted(false);
ComponentTitledBorder componentBorder =
new ComponentTitledBorder(radio, proxyPanel
, BorderFactory.createEtchedBorder());
checkBox.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
boolean enable = checkBox.isSelected();
Component comp[] = proxyPanel.getComponents();
for(int i = 0; i<comp.length; i++){
comp[i].setEnabled(enable);
}
}
});
radio.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent e){
boolean enable = radio.isSelected();
Component comp[] = proxyPanel.getComponents();
for(int i = 0; i<comp.length; i++){
comp[i].setEnabled(enable);
}
}
});
proxyPanel.setBorder(componentBorder);
JFrame frame = new JFrame("ComponentTitledBorder - santhosh@in.fiorano.com");
Container contents = frame.getContentPane();
contents.setLayout(new FlowLayout());
contents.add(proxyPanel);
frame.pack();
frame.setBounds(200, 200, 400, 400);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}
}
