如果复选框在Tkinter上，则保存其值

Question

我需要帮助。当我保存“box”的值时，它只写“！checkbutton”而不是我想要的值。为什么会发生这种情况以及如何解决它。 所以我希望它在txt中写入onvalue，而不是。！勾选复选框时，选中按钮 如何解决这个问题 此外，如果有办法使复选框变大，我将不胜感激：）

尝试将功能更改为以下内容：

def run():
  # getting the name
    filename = filename_ent.get()

    if filename == '':
        # to show an error that boxes are empty
        messagebox.showerror('Empty Box', 'Make sure to to fill the filename box.')
    elif os.path.exists(f'{filename}.txt'):
        # to show an error if the file already exists
        messagebox.showerror(
            'File exists', 'File already exists, try some other name not used before')
    else:
        # to open the file for python
        new = open(f'{filename}.txt', '+w', encoding='utf-8')
        # to write the name and email inside the file
        new.write(f'Admin of the event: {clicked.get()}\n{responsible.get()} \n{var.get()}')
        lfilename.config(text=f'The Feedback has been written successfully!')  # to change the label to the name
        os.startfile(f'{filename}.txt')  # to open the file in a new window

简言之，您忘了调用var.get()，而是说box，这就是checkbutton本身

另外，我将第二个if语句更改为elif，因为有多个if将导致第二个if被执行，无论第一个if上的条件是什么。只要试着用你的代码说一个空文件名，你就会发现问题所在

希望这有帮助，如果有任何错误或疑问，请务必让我知道
