java按钮和标签出现在菜单的JPanel上
我真的希望你能帮我解决这个问题。 我在一个NetBeans应用程序中工作，我用一个JPanel创建了一个动画幻灯片菜单，所以我打算让用户显示滑动的菜单，并覆盖应用程序中当前面板的部分内容，用户与菜单交互（按下菜单上的一个按钮），然后再次隐藏菜单幻灯片
隐藏和显示菜单的照片：
我在这里的问题是，如果菜单（当菜单被释放时）覆盖的内容中有一个jButton或jLabel，它们只是覆盖菜单的内容，它们保持可见，并且它们位于菜单内容的前面
这里的问题：
我尝试过在菜单出现时使用ButtonOrLabel.setVisible(false)方法，通过隐藏一些按钮和标签来修复它，一旦用户按下隐藏菜单的按钮，它们就会再次被设置为可见，然而维护这是一场噩梦，因为我的应用程序非常大，我需要对每个元素（按钮、翻领、面板等）进行管理当它被释放时，会被菜单覆盖
以下是我的jFrame结构：
我注意到的另一个问题是，当按下某个面板中的按钮或用户调整应用程序窗口的大小时，菜单会在中间弹出。它只是立即出现，没有任何动画
那么我做错了什么？如何完成修复？ 谢谢
“编辑后：” 我在这里加入了一些代码来说明这个问题。是MRE版本的主要问题

据我所知，我确信你可以复制并编译这段代码，希望你能重现我所描述的问题
# 1 楼答案
好吧，仍然不是MRE，因为：
所以你只需要：
所有其他组件都与您描述的问题无关
我能解决一些问题，但不是所有问题
鼠标事件被传递给添加了鼠标侦听器的组件。当菜单可见时，当鼠标移动到菜单下的按钮上时，您在菜单上移动鼠标，该按钮会被绘制，因为该按钮添加了鼠标侦听器来处理按钮的滚动效果
在大多数情况下，我可以通过在面板上添加一个假鼠标听筒来防止这种情况：
但是，当您单击“显示菜单”按钮，然后移动鼠标时，仍然会出现问题。不知道为什么
你的逻辑只会操纵setSize（…）方法来隐藏/显示它
但是，当调整框架大小时，将调用布局管理器，该管理器将根据菜单的首选大小重置菜单的大小（），并重新绘制菜单
我使用的解决方案是添加：
在“隐藏菜单”逻辑中添加
在“显示菜单”逻辑中
我从未使用过群组布局。我也不使用布局管理器来显示三维组件，所以我不确定使用GroupLayout是否是解决此类问题的最佳方案
也许相反，菜单应该是框架的
Glass Pane，您可以在需要时显示/隐藏该框架或者你应该使用JLayeredPane
以上两种设计都可以更好地在层中显示组件
