我用 Tkinter 编写了一个密码生成器，并设置了一个 messagebox，当网站的数据已经在数据库中时它会弹出.是否有允许我从弹出窗口复制文本的选项?因为这些密码真的很长.或者我需要进入保存它的文件来复制它吗?

I've written a password generator with Tkinter and have set a messagebox that pops-up when the data for the website is already in the database. Is there an option that allows me to copy the text from the pop-up? Because these passwords are really long. Or do I need to go into the file where it is saved to copy it?

messagebox.showinfo(title=website, message=f" Email: {email}\nPassword: {password}")

推荐答案

试试这个:

import tkinter as tk


class Popup:
    def __init__(self, title:str="Popup", message:str="", master=None):
        if master is None:
            # If the caller didn't give us a master, use the default one instead
            master = tk._get_default_root()

        # Create a toplevel widget
        self.root = tk.Toplevel(master)
        # A min size so the window doesn't start to look too bad
        self.root.minsize(200, 40)
        # Stop the user from resizing the window
        self.root.resizable(False, False)
        # If the user presses the `X` in the titlebar of the window call
        # self.destroy()
        self.root.protocol("WM_DELETE_WINDOW", self.destroy)
        # Set the title of the popup window
        self.root.title(title)

        # Calculate the needed width/height
        width = max(map(len, message.split("\n")))
        height = message.count("\n") + 1
        # Create the text widget
        self.text = tk.Text(self.root, bg="#f0f0ed", height=height,
                            width=width, highlightthickness=0, bd=0,
                            selectbackground="orange")
        # Add the text to the widget
        self.text.insert("end", message)
        # Make sure the user can't edit the message
        self.text.config(state="disabled")
        self.text.pack()

        # Create the "Ok" button
        self.button = tk.Button(self.root, text="Ok", command=self.destroy)
        self.button.pack()

        # Please note that you can add an icon/image here. I don't want to
        # download an image right now.
        ...

        # Make sure the user isn't able to spawn new popups while this is
        # still alive
        self.root.grab_set()
        # Stop code execution in the function that called us
        self.root.mainloop()

    def destroy(self) -> None:
        # Stop the `.mainloop()` that's inside this class
        self.root.quit()
        # Destroy the window
        self.root.destroy()


def show_popup():
    print("Starting popup")
    Popup(title="title", message="Message on 1 line", master=root)
    print("Ended popup")
    print("Starting popup")
    Popup(title="title", message="Message\nOn 2 lines", master=root)
    print("Ended popup")

root = tk.Tk()
root.geometry("300x300")

button = tk.Button(root, text="Click me", command=show_popup)
button.pack()

root.mainloop()

它只是一个简单的类，其行为很像 messagebox.showinfo.如果需要，您可以添加图标.请注意，缺少某些功能，但它应该适用于您的代码.

It's just a simple class that behaves a lot like messagebox.showinfo. You can add an icon if you want. Please note that some of the functionality is missing but it should work with your code.
