Question

我有标签FirstName，LastName和License。在我的程序中，我希望它们向左对齐，但我希望它们与它们下方的输入框齐平。目前，它们向左移动了一点。我没有太多的运气让他们过一点点。有什么建议吗？

您可以使用标签的padding选项在窗口小部件的边框内添加填充。

来自文档：

指定要为窗口小部件分配的额外空间量。填充是左上角右下角最多四个长度规格的列表。如果指定的元素少于四个，则默认为top，right默认为left，top默认为left。

例如：

self.last = ttk.Label(..., padding=(2,0,0,0))

您可以在调用grid时使用padx：

self.last.grid(..., padx=20)

但是，最后一个似乎没有区别，因为稍后在代码中将padx和pady值重置为零。您需要删除padx的代码才能生效。

如何在Tkinter / TTK中稍微移动标签中的文本？
