我已经运行 Eclipse Indigo 几个月了，我遇到了一个我似乎无法找到答案的错误。我正在创建一个类似于马里奥、旧塞尔达等的小型 2d 横向卷轴游戏。
我打算向我父亲展示我在程序中添加的新功能。我父亲没有上楼在我的电脑上查看我的程序，而是决定他可以使用我不确定的 sudo 屏幕查看工具进入它。这个我们以前用过，基本上它只是让你看到家里另一台电脑的屏幕（在同一个IP接口上），你也可以使用这台电脑。
我不想这样给爸爸看我的节目，所以我叫他上楼来。他做到了，从那时起，eclipse 将不会在您的程序中显示您的 JFrame 内的任何图形。它将显示诸如文字（写在屏幕上）之类的东西，但不会显示任何图形。比如你的背景图片，或者你的角色，或者其他任何东西。我很肯定我的编码没有问题，因为在我父亲进行屏幕查看之前，我已经测试并玩了很多次游戏（我们都在 linux mint 12 上，顺便说一句）。
我认为这个错误与屏幕查看有关。
如果我能得到一些帮助，我会很高兴的。任何都会很棒。谢谢。
