我一直在尝试完成这个终极井字游戏，但我在一个损失在哪里我出了错。我的问题是，当我编译和运行的代码，我得到的是一个空白的图形用户界面Blank GUI。除此之外，代码在后台工作。它只是没有显示构成游戏的垂直和水平线以及棋子。身份证赞赏任何帮助或只是指出我在正确的方向感谢。终极井字游戏的GUI是空白的，每次我运行我的代码
我希望重新看看我的代码会看到我缺少的东西。这是我的XOBoard代码

你已经张贴了大量的代码。当您仅提取重要部分和精确问题时，您很可能会得到一些帮助。 – Kacper
你有没有看到我发布的代码运行时显示的链接（空白图形用户界面）。但我的代码指出，它应该有一个黑色的背景，白色的垂直和水平线..我不知道我错了那就是为什么我提出这两个类.. – enat
我只是想告诉你，并不多人们会阅读你的代码，因为它有很多。 – Kacper
