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（并非总是）我创建的 jframe 与我在属性中设置的大小不同。我使用 Netbeans 7.1.2 并且只拖放用于 GUI 制作。我还不能进行 GUI 编码。这是例如图片

我的窗口组件看起来像被裁剪了。运行时的大小和属性中的大小（最小和首选大小）不同。这发生在自由设计或绝对设计中。这是什么问题？你知道这通常有什么问题吗？我不知道会发生什么。我该如何解决这个问题？我对错误感到抱歉。谢谢你。

我不知道代码中的错误在哪里，但这是该框架的代码：

    pack();

不是完整的代码，但可能有用。谢谢大家的关注...

...AbsoluteConstraints(117, 12, 578, -1)

这是问题的基础。null使用时它与布局一样有效pack()。

解决方案很简单。使用符合组件首选尺寸的布局管理器。
