我正在失去理智试图弄清楚这一点。

我的 Python3 Checkbutton 引用 IntVar() 不起作用。每当我在 IntVar 上调用 get() 时，即使选中/选中复选框，我总是得到 0。其他一切，例如。StringVar，Entry 工作正常。

提前感谢您的帮助。

请看下面的配置。

尝试为您的按钮使用 .state() 方法

>>> print(updateOrdertkCheckordstatusCbutton.state())  # checked
('selected',)
>>>> print(updateOrdertkCheckordstatusCbutton.state())  # not checked
()
