JFrame我应该怎么做（包括图片）？

标签： java swing jframe

目前我正在体验与Java制作相关的事情，我想尝试制作如下所示的GUI：

enter image description here

你是如何建议的？

首先，我创建了一个名为“My Frame”的类，它将包含一个包含每个多边形点的数组（因此每个多边形将是一个单独的框架）。

但是经过重新思考后，我想到了这些三角形的目的，我想让它们成为按钮，每次按下其中一个按钮会改变八角形内的内容，所以它更像是三角形的按钮和Octagon本身就是内容窗格，所以你们怎么建议我实现这个目标呢？

另一个相关的问题是，我想让这些三角形与八角形一起移动，如果用鼠标拖动八角形，三角形也随之移动，那么我应该将它们放到八角形框架中吗？ / p>

我想问的另一件事是，因为我将框架设置为未修饰以改变它的形状我取消了调整框架大小的选项以及我使iconify和关闭按钮消失，所以怎么能我添加了这些功能，我搜索了网络，但我没有找到任何解释。

最新编辑： @peeskillet抱歉没有在这里过去几天，家人在医院..我试图实现你所说的我为角三角形做了不同的鼠标监听器，但我遇到了一个问题，mouseEntered和MouseExited事件得到了当鼠标位置带有标签的BORDER（而不是多边形）时调用，所以如果我将鼠标输入标签的边框（但鼠标的位置仍然在多边形之外）然后我决定移动鼠标（虽然我仍然在标签的边框内）在多边形的边框内，它不会检查它是否在里面，因为mouseEntered已被调用，并且在该方法中检查多边形内部的点（相同）问题为mouseExited）所以我尝试了而不是覆盖mouseEntered和mouseExited做我自己的方法只是调用它们mouseEntered2和mouseExited2我每次鼠标移动时都调用它们与mouseMoves事件，但是在我移动mo之后这样做使用它甚至不会被称为mouseMoved事件，我不知道为什么..这里是代码：

只需使用图片。从your last post开始，您试图创建框架的形状。但你可以使用透明图像。
