You can find the frame insets by calling the getInsets method (defined in Container). Frame insets are discussed at the top of the Frame API docs. See this question.
您可以通过调用 getInsets 方法（在 Container 中定义）来找到框架插图。Frame 插入在 Frame API 文档的顶部讨论。看到这个问题。
Of course you could always add your mouse listener to the content pane. JFrame has some unexpected behaviour on some methods such as addand setLayout.
当然，您始终可以将鼠标侦听器添加到内容窗格中。JFrame 在某些方法（例如add和 ）上有一些意外行为setLayout。
