7x4 网格显示 1 个按钮 28 次，而不是显示 28 个不同的按钮为什么？

分类：编程问答

如何解决7x4 网格显示 1 个按钮 28 次，而不是显示 28 个不同的按钮为什么？

我想在 7x4 自动调整大小的网格中显示下面的 28 个按钮。就目前而言，相等按钮显示了 28 次。我需要在 7x4 网格中显示所有 28 个不同的按钮。我用 row_index 和 col_index 变量配置了所有 28 个不同的按钮，但它仍然无法正常工作。如果您能帮助我找到正确的方向，我将不胜感激。

解决方法

您将所有控件置于 row=row_index,column=col_index。到运行时，row_index 为 7，col_index 为 4。您需要对所有这些按钮的位置进行硬编码，如 row_index=0,col_index=3。然后它会起作用。我现在正在看：
