使用嵌套面板
试图为我的游戏构建一个图形用户界面，但无论我使用什么布局，我都无法让面板的嵌套做我喜欢的事情
我的目标是这样的 http://i182.photobucket.com/albums/x202/NekoLLX/CharGenmockup-1.jpg http://i182.photobucket.com/albums/x202/NekoLLX/CharGenmockup2.jpg在疯狂版本的基础上我得到了我喜欢的左侧，但现在右侧离开了我
大意是，单击左侧菜单的标题栏将覆盖与其相关联的内容窗格(将Visible设置为False)

类似于...
老实说，我试着遵循您的代码，但迷路了，所以我重写了它...
基本上，您所依赖的setSize将被布局管理器忽略并在他们认为合适的时候进行更改。
此示例使用GridBagLayout和weighty调整分配给顶视图(2D/3D)和底视图的空间，但您还应了解如何覆盖最终组件的getPreferredSize，以便为布局管理器提供更好的提示。
