无法更改CheckButton变量值

问题描述

我的checkbtn值有点问题。

这是我的代码：

def select_data():
        select_window = Tk()

        var_autoTrader = Intvar()
        check_sites_autoTrader = Checkbutton(select_window,text = 'autoTrader',variable = var_autoTrader)
        var_bestcarfinder = Intvar()
        var_cardady = Intvar()
        var_cars = Intvar()
        var_car_gurus = Intvar()
        var_iseecars = Intvar()
        var_truecar = Intvar()

        check_sites_bestcarfinder = Checkbutton(select_window,text = 'bestcarfinder',variable = var_bestcarfinder)
        check_sites_cardaddy = Checkbutton(select_window,text = 'cardady',variable = var_cardady)
        check_sites_cars = Checkbutton(select_window,text = 'cars.com',variable = var_cars)
        check_sites_car_gurus = Checkbutton(select_window,text = 'car gurus',variable = var_car_gurus)
        check_sites_iseecars = Checkbutton(select_window,text = 'iseecars',variable = var_iseecars)
        check_sites_truecar = Checkbutton(select_window,text = 'truecar',variable = var_truecar)

        check_sites_autoTrader.grid(row = 0,column = 0,sticky = W)
        check_sites_bestcarfinder.grid(row = 1,sticky = W)
        check_sites_cardaddy.grid(row = 2,sticky = W)
        check_sites_cars.grid(row = 3,sticky = W)
        check_sites_car_gurus.grid(row = 4,sticky = W)
        check_sites_iseecars.grid(row = 5,sticky = W)
        check_sites_truecar.grid(row = 6,sticky = W)
         def upload_selected_data():
            print(var_autoTrader.get())// This one does not give me 1 when check is on
            

        btn = Button(select_window,text = 'go!',command = upload_selected_data)
        btn.grid(row = 7,sticky = W+E)

麻烦的是，当我选中复选框时，我的变量没有改变

非常感谢您！

解决方法

可能您是使用Tk()创建了“主窗口”。在这种情况下，您应该使用Toplevel()（而不是Tk()）创建另一个窗口。

这意味着您应将select_window = Tk()行更改为select_window = Toplevel()

python tkinter tkinter.checkbutton
