设置tkinter复选框默认值的多帧

Question

我想将我的单窗口tkinter GUI逐步移动到多窗口。我试图将名为checkb_ult_tubo的复选框的默认值设置为1（已选中），但尽管我将变量设置为1，默认情况下该复选框仍处于关闭状态。 我甚至尝试在Page5X类块中清除一个新变量（tk.IntVar），并将其设置为1，但复选框仍然显示

这是我的密码

Answer 1

所以我注意到checkb_ult_tubo中的onvalue是0，offvalue是1。我认为当您将复选框的值设置为1时，它保持关闭状态，因为offvalue为1。试试这个：

        checkb_ult_tubo = tk.Checkbutton(sub_frame2,
                                     text="Ultimo rack completo",
                                     variable=self.controller.shared_data['rack_completo_check'],
                                     height=1,
                                     width=15,
                                     command=disable_enable_button,
                                     onvalue=1, offvalue=0)
