Question

我正在尝试创建一个自动跟踪器，但我遇到了一个随机问题我做了退出＆＃34;退出＆＃34;使用 .getContentPane（）生成右下角的按钮.getSize（）
但在我的基本＆＃34; Jframe的值有些变化（我在打开时添加了系统打印第一个值是 java.awt.Dimension [width = 284，height = 462]
第二个是 java.awt.Dimension [width = 294，height = 472] （这是正确的）
有人可以解释为什么会发生这种情况，因为我的思绪被吹了我正在使用NetBeans 这不是我的完整代码：

    BasicClicker.setLocation(CW(Homef.getContentPane().getSize().width, BasicClicker.getWidth()), BasicClicker.getY());   
  }
 }

注意我尝试删除第一帧，然后立即打开基本帧当我这样做的时候，问题就解决了（我想，我跑了30次没有出现问题），但是......我不知道为什么......帮助！

为什么Jframe size SOME TIME会自行更改？
