我需要制作一个最终看起来像这样的程序:

到目前为止,我的代码就是发布的内容,我似乎无法全神贯注于如何使它看起来与我提供的图像完全一样。我真的不知道我还能做什么,我试过四处寻找解决方案,但我无法设法将这些信息与这些信息结合起来使它们一起工作。

所以,我希望其他人可以在这里帮助我,我们将不胜感激! :D

这就是我认为答案建议我做的事情。就像我说的那样,当我也有按钮 10 时,我看不到我的面板 4,我确定这是我看不到但仍然看到的东西。

所以现在我对它进行了一些润色,并尝试按照您所说的去做,但现在它看起来更糟了,所以一定有一些我没有完全理解的东西,哈哈。希望你能看到我的错误。

好吧,我说得更远了,现在最大的问题是按钮 11-18 没有出现在按钮 7-10 的中间。

最佳答案

我会用 3 个网格布局和一个边框布局来实现。例如

  • GridLayout 左/右部分(每个部分一个面板)
    1. GridLayout 按钮 1-6
    2. BorderLayout for buttons 7-10 + panel in CENTER for..
      • GridLayout 按钮 11-18
