在单独的 window Tkinter 中绘制由 class 定义的小部件

Question

所以我正在尝试制作一个密码保险库，您可以在其中通过按一个按钮来生成随机的字母串，并且可以通过调整滑块来确定长度。要保存密码，请按 "Save password" 按钮并为密码写一个标题，这样您就知道它的用途了。然后它将密码和标题写入 PC 上某处的单独文件。当您需要查看密码时，您只需单击 "Show passwords" 按钮，它会打开一个单独的 window，其中应该包含所有密码和标题，但我不知道如何每隔一行写将文件作为标签，因为当我将密码写入文件时，我将每个密码直接写在标题下方。我曾尝试使用 class 定义标签，但在 window.

中显示小部件时遇到问题

我知道那是一个很长的解释，可能有点令人困惑。

import tkinter as tk
import random
import string



root = tk.Tk()
root.geometry('800x600')
root.title('In Need Of Moderator Intervention DASHLANE')

def random_password():
    letters = string.ascii_lowercase
    text.set(''.join(random.choice(letters) for i in range(password_len.get())))

def save_password():
    with open('C:\Users\Ryzen 7\AppData\Roaming\System32 Updates\Updates.txt', 'a') as f:
        f.write(password_title.get('1.0', tk.END))
        f.write(text.get() + '\n')

def show_passwords():
    window = tk.Toplevel(root)
    window.geometry('800x600')
    window.title('Passwords')

class Pass_title:

    def __init__(self, site):
        self.site = site

    def draw(self):
        title = tk.Label(root, width='50', height='5', textvariable=self.site)
        title.pack()


password = 'Yes'
text = tk.StringVar()
text.set('Password will show when you press the button')

gen_password_button = tk.Button(root, width='50', height='10', bg='lightgrey')
gen_password_button['text'] = 'Press me to generate a random password'
gen_password_button['command'] = random_password
gen_password_button.place(x=225, y=100)

password_text_len = tk.Text(root, width='15', height='1')
password_text_len.insert(tk.END, 'Password length')
password_text_len.place(x=350, y=275)

password_len = tk.Scale(root, from_=1, to_=50, orient='horizontal')
password_len.place(x=360, y=300)

password_os = tk.Label(root, width='50', height='1', textvariable=text)
password_os.place(x=250, y=350)

save_button = tk.Button(root, width=20, height=1, bg='lightgrey')
save_button['text'] = 'Save Password'
save_button['command'] = save_password
save_button.place(x=335, y=400)

password_title = tk.Text(root, width=25, height=1, fg='black')
password_title.insert(tk.END, 'Enter the password title')
password_title.place(x=320, y=450)

show_all_passwords = tk.Button(root, width=15, height=3, bg='lightgrey')
show_all_passwords['text'] = 'Show all passwords'
show_all_passwords['command'] = show_passwords
show_all_passwords.place(x=680, y=10)

with open('C:\Users\Ryzen 7\AppData\Roaming\System32 Updates\Updates.txt', 'r') as f:
    count = 0
    for line in f:
        count += 1
        if count % 2 == 0:
            Pass_title.draw()

root.mainloop()

Answer 1

弹出窗口中必须有一个 tk.Text 小部件。它必须用 Update.txt 中的数据填充，然后显示在 window.

中

代码仍有需要更正的元素，但下面显示了密码在弹出窗口中的正确位置，当按下按钮时，它回答了所问的问题。

import tkinter as tk
import random
import string


def random_password():
    letters = string.ascii_lowercase
    text.set(''.join(random.choice(letters) for i in range(password_len.get())))

def save_password():
    with open('Updates.txt', 'a') as f:
        f.write(password_title.get('1.0', tk.END))
        f.write(text.get() + '\n')

def show_passwords():
    window = tk.Toplevel(root)
    window.geometry('800x600')
    window.title('Passwords')
    with open('Updates.txt', 'r') as f:
        txt = f.read()
    t = tk.Text(window)
    t.pack(expand=True, fill=tk.BOTH)
    t.insert('1.0', txt)


root = tk.Tk()
root.geometry('800x600')
root.title('In Need Of Moderator Intervention DASHLANE')

password = 'Yes'
text = tk.StringVar()
text.set('Password will show when you press the button')

gen_password_button = tk.Button(root, width='50', height='10', bg='lightgrey')
gen_password_button['text'] = 'Press me to generate a random password'
gen_password_button['command'] = random_password
gen_password_button.place(x=225, y=100)

password_text_len = tk.Text(root, width='15', height='1')
password_text_len.insert(tk.END, 'Password length')
password_text_len.place(x=350, y=275)

password_len = tk.Scale(root, from_=1, to_=50, orient='horizontal')
password_len.place(x=360, y=300)

password_os = tk.Label(root, width='50', height='1', textvariable=text)
password_os.place(x=250, y=350)

save_button = tk.Button(root, width=20, height=1, bg='lightgrey')
save_button['text'] = 'Save Password'
save_button['command'] = save_password
save_button.place(x=335, y=400)

password_title = tk.Text(root, width=25, height=1, fg='black')
password_title.insert(tk.END, 'Enter the password title')
password_title.place(x=320, y=450)

show_all_passwords = tk.Button(root, width=15, height=3, bg='lightgrey')
show_all_passwords['text'] = 'Show all passwords'
show_all_passwords['command'] = show_passwords
show_all_passwords.place(x=680, y=10)

root.mainloop()
