关于ToolTip

[yuchicsd]

private void initialize()
{
setBounds(420, 5, 480,720);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
getContentPane().setLayout(null);
image=new ImageIcon("\\Turnoff.png").getImage();
jtooltip=new JToolTip();
jtooltip.setComponent(this.getContentPane());//这句有错，我要实现在移动鼠标时在ToolTip中显示坐标该怎么写，鼠标在JFrame的ContentPane中移动
setVisible(true);

getContentPane().addMouseMotionListener(new MouseMotionAdapter() {
public void mouseMoved(MouseEvent e)
{
s=new String(e.getX()+","+e.getY());
jtooltip.setTipText(s);
}
});

没人回复吗？

[gentalguo]

t.setComponent((JComponent) getContentPane());
参数类型不对

但是。我可以保证你这样也出不来你想要的效果。
应该是这样：

import java.awt.Container;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionAdapter;

import javax.swing.JComponent;
import javax.swing.JFrame;

public class ToolTipDemo extends JFrame {
	public ToolTipDemo() {
		super();

		Container c = getContentPane();

		final JComponent jc = (JComponent) c;

		jc.addMouseMotionListener(new MouseMotionAdapter() {
			@Override
			public void mouseMoved(MouseEvent e) {
				jc.setToolTipText(e.getX() + "," + e.getY());
			}
		});

		setSize(600, 400);
		setDefaultCloseOperation(EXIT_ON_CLOSE);
		setLocationRelativeTo(null);
		setVisible(true);
	}

	public static void main(String[] args) {
		new ToolTipDemo();
	}
}
