如有如何实现，没有的话也请告之实现的代码。谢谢。
1)简单些
public class Compement_Titleborder_study2 extends JFrame {
public Compement_Titleborder_study2() {
super("Compement_Titleborder_study2");
JCheckBox title = new JCheckBox("Title");
title.setSelected(true);
/*p1.setEnabled(false);//可用这句来完成：初始为disable
*/
final CompTitledPane p1 = new CompTitledPane(title);
title.addItemListener(new ItemListener() {
public void itemStateChanged(ItemEvent e) {
p1.setEnabled(e.getStateChange() == ItemEvent.SELECTED);
}
});
APanel p2 = new APanel();
p1.setTransmittingAllowed(true);//???
p1.setTransmitter(p2);
p1.getContentPane().add(p2);
getContentPane().add(p1, BorderLayout.CENTER);
}
class APanel extends JPanel implements StateTransmitter {
JButton button;
JTextField textField;
APanel() {
button = new JButton("abc");
button.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
System.out.println("Ouch!");
}
});
textField = new JTextField(10);
textField.setText("text");
add(button , BorderLayout.NORTH);
add(textField, BorderLayout.SOUTH);
}
public void setChildrenEnabled(boolean enable) {
button.setEnabled(enable);
textField.setEnabled(enable);
}
}
public static void main (String args[]) {
Compement_Titleborder_study2 frame = new Compement_Titleborder_study2();
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
frame.setSize(280, 110);
frame.setVisible(true);
}
}
2)复杂些
