问题描述
限时送ChatGPT账号..我查看了几个在线教程，它们似乎都无法正常工作，单击清除按钮后，我需要取消选择单选按钮..deselect() 方法什么都不做.清除文本和输入框工作正常.请协助.
I have looked at several online tutorials, none of them seem to work properly, I need to have the radio button deselected once the clear button is clicked. The .deselect() method does nothing. Clearing the text and entry boxes is working properly. Please assist.
谢谢，

推荐答案
self.SrcDstport.deselect()
您正在尝试取消选择 StringVar.您需要将其设置为不是选项的值，换句话说，值参数中没有单选按钮使用的值:
You are trying to deselect the StringVar. You need to set it to something that isn't an option, in other words a value that none of the Radiobuttons use in the value argument:
self.SrcDstport.set(None)
