我在玻璃窗格下有兩個圖像的代碼。我想要讓每個圖像都在它自己的玻璃窗格下，並且每個玻璃窗格都有自己的mouselistener信號。目前，我已經將它們兩個放在一個玻璃板下面，一個鼠標器用於整個玻璃板。兩幅圖像並排排列，因此將玻璃板分成兩半不應太難。這裏是一個玻璃窗格的代碼，但請注意，我正在嘗試製作兩個玻璃窗格，並且兩個單獨的鼠標監聽器類爲每個圖像。這僅僅是與的**都圖像一個*鼠標監聽代碼：我可以將玻璃窗格分成兩部分，併爲每個窗格添加一個單獨的mouselistener？

giraffewindow.setLayout(new GridLayout(1, 2, 0, 0));
giraffewindow.add(new JLabel(windows));
giraffewindow.add(new JLabel(giraffe));
giraffewindow.pack();
giraffewindow.setTitle("GIRAFFE!");
giraffewindow.setVisible(true);
giraffewindow.setDefaultCloseOperation(DISPOSE_ON_CLOSE);

glass.add(status);

glass.addMouseListener(giraffemouse);
glass.addMouseMotionListener(giraffemouse); //Can I add mouse motion listener to a picture
// setLayout(null);
}
JLabel status = null;
class giraffemousehandler extends MouseAdapter implements MouseListener, MouseMotionListener { //MouseAdapter makes it so that you don't have to have all 7 implemented mouse listener methods
@Override
public void mouseMoved(MouseEvent e) {
// TODO Auto-generated method stub
status.setBounds(e.getX(), e.getY(), 50, 60); //Makes JLabel follow mouse
}
@Override
public void mouseEntered(MouseEvent e) {
status.setText("Enter);
}
@Override

這裏是camickr的請求的代碼，請注意，是兩個不同的鼠標監聽，我很想知道如何做到這一點除此以外。當JLabel遵循鼠標時，1）它離鼠標非常遠，2）它沒有顯示完整的JLabel，3）它在一次退出/輸入後不會改變。我真的很感激的幫助下，這裏是基於camickrs建議代碼：

考慮在看看'JLayer'（用於Java 7，'JXLayer'之前） – MadProgrammer
這是什麼你試圖做的實現？您想要在與玻璃窗格不同的圖像上發生什麼操作？ – MadProgrammer
@MadProgrammer我想在每個圖像上有不同的事件。玻璃窗格就在那裏，以便JLabel不會出現在圖片的下方 –
