java - JFrame 大小不一致

Question

我的窗口组件看起来像是被裁剪过的。运行时的大小和属性中的大小(最小大小和首选大小)不同。无论是自由设计还是绝对设计，都会发生这种情况。我使用 Netbeans 7.1.2 完成了这些工作。 这有什么问题吗？你知道这通常是什么问题吗？是Matisse的bug吗？我不知道会发生什么。 我该如何解决这个问题？对于错误，我深表歉意。谢谢。

我不知道代码的错误在哪里，但这是该框架的代码:

Answer 1

通常 setPreferredSize 应该适用于大多数布局管理器。您的布局管理器将使用组件的首选尺寸以及最小和最大尺寸，然后使用 setSize 和 setLocation 根据布局规则定位这些组件。

但是，如果您尝试将组件放置在太大而无法容纳的位置，布局管理器将自动调整大小以适合该组件，并且可能不会遵循 setPreferredSize 中设置的尺寸。
