我为一个朋友写了一个价格计算器（runescape dungeoneering，但这并不是特别重要）。他是一个相当大的团队中的一员，而其他管理员之一在这方面遇到了麻烦。
我在 Windows 7、Java 6u32（我相信是 u32）上的 Eclipse 中编写了这个。他正在运行 Mac OS X 版本 10.7.4，Java 6u33。每当他加载页面时，文本字段都无法正确显示。其中一半在行尾用椭圆缩短。
问题图片：
另外，作为一个附带问题，我想知道为什么图像只在绘制一次后才出现？
感谢您的所有帮助，并对命名错误的变量感到抱歉！我无法弄清楚如何将代码正确嵌入到帖子中，所以我意识到这是非常糟糕的空间 - 我只是复制/粘贴它并使用空间来缩进导入：/。
