我的任务
分享Java Swing JFrame大小不一致
这是我在Stackoverflow中的第一个问题.我从这里收集了很多页面,并没有解决我的问题.我的问题有时(并不总是)我创建的jframe,看起来与我在属性中设置的大小不一样.我使用Netbeans 7.1.2并且只能拖放以进行GUI制作.我还不能做GUI编码.这就是图片
我的窗口组件看起来像是裁剪的.运行时的大小和属性中的大小(minimumsize和preferredsize)是不同的.这与自由设计或绝对设计都发生过.这是什么问题？你知道这个常见的问题吗？我不知道发生了什么.我该如何解决这个问题？对不起,我很抱歉.谢谢.
我不知道代码中的错误,但这是该框架的代码：

不完整的代码,但也许有用.谢谢你的关注……

...AbsoluteConstraints(117, 12, 578, -1)
这是问题的基础.使用pack()时,它与null布局一样有效.
解决方案很简单.使用符合组件首选大小的布局管理器.
