问题描述

I am getting a MouseEvent in Java. the getPoint() method is adding the height of the title bar into the y portion of the coordinate.

I我想知道如何找到当前窗口标题栏的高度，以便将y值偏移正确的数量。

I was wondering how I can find the height of the title bar of the current window in order to offset the y value by the correct amount.

推荐答案

您可以通过调用getInsets方法（在Container中定义）来查找帧插入。帧插入在Frame API文档的顶部进行了讨论。 查看此问题。

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.

当然，您总是可以将鼠标监听器添加到内容窗格中。 JFrame在某些方法上有一些意想不到的行为，例如 add 和 setLayout 。

Of course you could always add your mouse listener to the content pane. JFrame has some unexpected behaviour on some methods such as add and setLayout.
