java获取鼠标坐标
//你运行一下，看在你的电脑上能不能用。
//不能用的话肯定是坐标不对
//把mouseMoved方法里的注释去掉重新获取

java获得鼠标相对于窗体的坐标
有的，你可以去继承MouseEvent这个类，里面有个方法叫做,getXOnScreen()和getYOnScreen(),
getXOnScreen
public int getXOnScreen()
返回事件的绝对水平 x 坐标。在虚拟设备多屏幕环境中，桌面区域可以跨越多个物理屏幕设备，这些坐标相对于虚拟坐标系。否则，这些坐标相对于与
Component 的 GraphicsConfiguration 关联的坐标系。
返回：
x 表示绝对水平位置的整数。
getYOnScreen
public int getYOnScreen()
返回事件的绝对垂直 y 坐标。在虚拟设备多屏幕环境中，桌面区域可以跨越多个物理屏幕设备，这些坐标相对于虚拟坐标系。否则，这些坐标相对于与
Component 的 GraphicsConfiguration 关联的坐标系。
返回：
y 表示绝对垂直位置的整数。
这个就是你在窗体（Frame里的位置了），希望能帮到你。
JAVA中如何获得当前鼠标选中的值
//类名 MyMouseLister
import java.awt.event.MouseEvent
import java.awt.event.MouseListener
public class MyMouseLister implements MouseListener{
public void mouseClicked(MouseEvent e){}
public void mouseEntered(MouseEvent e){}
public void mouseExited(MouseEvent e){}
public void mousePressed(MouseEvent e){}
public void mouseReleased(MouseEvent e){}
}
//类名OnMouseOver
import java.awt.GridLayout
import java.awt.event.MouseEvent
import javax.swing.JFrame
import javax.swing.JLabel
import javax.swing.JPanel
public class OnMouseOver extends MyMouseLister{
private JLabel test1
private JLabel test2
private JLabel test3
private JLabel test4
private JPanel p
private JFrame f
public OnMouseOver(){
test1 = new JLabel("test1.text")
test1.addMouseListener(this)
test2 = new JLabel("test2.text")
test2.addMouseListener(this)
test3 = new JLabel("test3.text")
test3.addMouseListener(this)
test4 = new JLabel("test4.text")
test4.addMouseListener(this)
p = new JPanel(new GridLayout(2,2))
p.add(test1,0)
p.add(test2,1)
p.add(test3,2)
p.add(test4,3)
f = new JFrame("Test")
f.add(p)
f.setVisible(true)
f.setBounds(300, 200, 300, 200)
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE)
}
//事件可以自己换
public void mouseEntered(MouseEvent e) {
if(e.getSource() == test1){
System.out.println(test1.getText())
}else if(e.getSource() == test2){
System.out.println(test2.getText())
}else if(e.getSource() == test3){
System.out.println(test3.getText())
}else if(e.getSource() == test4){
System.out.println(test4.getText())
}
}
public static void main(String[] args) {
new OnMouseOver()
}
}
希望能帮到你虽然这个是JLabel但是道理是相通的，你看看就明白了。
//附上操作表格的方法：
getSelectedColumn()返回列索引
getSelectedRow()返回行索引
getValueAt()返回单元格的值
