好的，所以我终于找到了！现在我只需要帮助了一件事。我需要检测我点击的位置，查看它是否在日历中，然后检测单击了哪个框。 如果你可以帮助我那将是惊人的!!!
这是我的代码！：

答案 0 :(得分：0)
您似乎在顶级MousListener上有JPanel，其中包含许多按钮。由于点击的焦点将随鼠标移动，您是否会验证您的点击是否落在JPanel上而不是其中一个内部子组件上？
如果是这样，可能有一个按钮正在处理鼠标点击。
答案 1 :(得分：0)
在我看来，您从未将鼠标面板添加到主JPanel或任何其他JPanel。也许这样做：
add(mousepanel); // With some kind of BorderLayout
答案 2 :(得分：0)
MouseClick应扩展MouseAdapter并覆盖mouseClicked(MouseEvent e)，而不是实施MouseListener并拥有大量未使用的方法。
无论如何，只需在构造函数中调用addMouseListener(new MouseClick());即可。您不需要MousePanel
