Question

尝试为我的游戏构建一个GUI，但无论我使用什么布局，我都无法让面板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

并且建立了疯狂的那些优秀的修改我已经得到了我的左侧，因为我喜欢但现在正确的躲避我

一般的想法是点击左侧菜单的标题栏会将与之关联的内容窗格进行协同处理（设置为可见为false）

有些事情......

老实说，我试过跟你的代码，但迷路了，所以我重新写了......

基本上，你依赖于setSize，它会被布局管理员忽略并在他们认为合适的情况下进行更改。

此示例使用GridBagLayout和weighty调整分配给顶部（2D / 3D）视图和底部视图的空间，但您还应该看一下覆盖{{1}最终组件，为布局管理器提供更好的提示。

getPreferredSize

使用嵌套面板
