【Java】重构默认的JTextField

作者:liu-xuewei / 发布于2013/3/1/ 616

重构默认的JTextField为双击后可编辑，失去焦点或按鼠标回车确定输入，不可编辑的组件JPasswordField的重构方式相同


	public class DefaultUnEditableJTextField extends JTextField implements MouseListener{
	private static final long serialVersionUID = -3996533656556699625L;
	public DefaultUnEditableJTextField(int columns) {
	 super(columns);
	 this.setEditable(false);
	 this.addMouseListener(this);
	}

	
	@Override
	public void mouseClicked(MouseEvent e) {
	 if(e.getClickCount()==2){
	 this.requestFocus();
	 this.setEditable(true);
	 }
	 final JTextField text=(JTextField)e.getSource();
	 text.addKeyListener(new KeyListener() {

	 @Override
	 public void keyTyped(KeyEvent e) {
	 }

	 @Override
	 public void keyPressed(KeyEvent e) {
	 if(e.getKeyCode()==KeyEvent.VK_ENTER){
	 text.setEditable(false);
	 }
	 }

	 @Override
	 public void keyReleased(KeyEvent e) {
	 }
	 });
	 text.addFocusListener(new FocusListener() {
	
	 @Override
	 public void focusLost(FocusEvent e) {
	 text.setEditable(false);
	 }
	
	 @Override
	 public void focusGained(FocusEvent e) {
	
	 }
	 });
	}

	@Override
	public void mousePressed(MouseEvent e) {
	}

	@Override
	public void mouseReleased(MouseEvent e) {
	}

	@Override
	public void mouseEntered(MouseEvent e) {
	}

	@Override
	public void mouseExited(MouseEvent e) {
	}
	}
