我不知道为什么我的代码可以在终端和Eclipse中正确运行，但不能单独作为jar文件运行

[英]I can't figure out why my code runs correctly in terminal and eclipse, but not as a jar file by itself

问题描述

我使用html更改Buttons的颜色，因为那是我可以更改Buttons的颜色并在禁用Button后保持颜色的唯一方法。 如果有人可以告诉我如何解决此问题，将不胜感激。

因此，正如我在评论中指出的，根本原因是按钮上的setEnabled(false) ，使按钮不可单击的一种方法是将setEnabled(false)替换为removeActionListener(this) 。 这将删除操作侦听器绑定，该绑定实际上使按钮在单击时不采取任何操作。

首先，老实说，我不知道为什么您的HTML颜色呈现功能取决于您启动应用程序的方式，但是无论如何，我建议您考虑使用setForeground(...)而不是HTML颜色呈现，因为您知道这可以使用，而不是在按钮或其Action上调用setEnabled(false) ，而是使用Model-View-Control或MVC程序结构，而不是停用按钮，而是停用模型 。 如果您以后想要调试和增强，那么这也将使调试和增强变得更加容易。 例如，在下面的代码中，模型类具有press(int row, int col)方法，该方法首先检查网格单元格是否包含X或O值或是否为空白。 如果不为空，则该方法返回/结束。 否则，它将继续设置模型网格单元的值并更改转弯值（即转弯的值）。 

public void press(int row, int col) {
   // if value already selected, ignore 
   if (valueGrid[row][col] != TttValue.BLANK) {
      return;
   }

这是我的整个代码：
