python - 选择、复制和粘贴表单 Tkinter Python 布局网格

Question

我需要选择、复制和粘贴我的表单 tkinter 的一些信息。但我做不到。我想复制名字“安吉丽娜朱莉”并粘贴到任何地方。我该怎么做？我需要使用网格布局来做到这一点。我发现了一些带有包装和放置的教程。但我只对 Lyaout Grid 感兴趣

from tkinter import *
from tkinter import ttk
import tkinter as tk

class Form:

    def __init__(self):
        pass

    def form(self):
        self.root = Tk()
        self.root.geometry('850x600')
        self.root.title("PVE - Formulário Estudar")

        self.canvas = tk.Canvas(bg='light blue', scrollregion=(0, 0, 1500, 3300))
        self.canvas.bind('<Enter>', self._bound_to_mousewheel)
        self.canvas.bind('<Leave>', self._unbound_to_mousewheel)
        self.canvas.pack(fill='both', expand=True)

        f = tk.Frame(self.canvas, background="light blue")

        # you need to create a window into the canvas for the widget to scroll
        self.canvas.create_window((5, 5), window=f, anchor="nw")

        yvbar = ttk.Scrollbar(self.canvas, orient='vertical', command=self.canvas.yview)
        xvbar = ttk.Scrollbar(self.canvas, orient='horizontal', command=self.canvas.xview)

        yvbar.pack(side='right', fill='y')
        yvbar.config(command=self.canvas.yview)

        xvbar.pack(side='bottom', fill='x')
        xvbar.config(command=self.canvas.xview)

        self.canvas.config(yscrollcommand=yvbar.set, xscrollcommand=xvbar.set)

        ttk.Label(f, width=20, text='Name: ', font='Arial 12 bold', background="light blue", anchor='w')\
        .grid(column=0, row=1, padx=20, pady=10)

        ttk.Label(f, width=40, text='Angelina Jolie', font='Arial 12 bold', foreground="blue",
              background="light blue").grid(column=1, row=1, padx=20, pady=10)

        self.root.mainloop()


    def _bound_to_mousewheel(self, event):
        self.canvas.bind_all("<MouseWheel>", self._on_mousewheel)

    def _unbound_to_mousewheel(self, event):
        self.canvas.unbind_all("<MouseWheel>")

    def _on_mousewheel(self, event):
        self.canvas.yview_scroll(int(-1 * (event.delta / 120)), "units")



if __name__ == '__main__':
    a = Form()
    a.form()

我不确定您是否要将值复制到剪贴板，或者您想询问如何将另一个元素的值设置为现有元素的值，但是，我添加了一个复制按钮，两者都可以，看看在下面的代码中了解我是如何做到的。

from tkinter import *
from tkinter import ttk
import tkinter as tk
import pyperclip


class Form:

    def __init__(self):
        pass

    def copy_name(self):
        # Get the current label value 
        user_name = self.name_label['text']
        # Copy the value to the clipboard 
        pyperclip.copy(user_name)
        # Update "paste" the value to the second label 
        self.copy_name_label.config(text=user_name)
        
        print("{} was copied to your clipboard".format(user_name))

    def form(self):
        self.root = Tk()
        self.root.geometry('850x600')
        self.root.title("PVE - Formulário Estudar")

        self.canvas = tk.Canvas(bg='light blue', scrollregion=(0, 0, 1500, 3300))
        self.canvas.bind('<Enter>', self._bound_to_mousewheel)
        self.canvas.bind('<Leave>', self._unbound_to_mousewheel)
        self.canvas.pack(fill='both', expand=True)

        f = tk.Frame(self.canvas, background="light blue")

        # you need to create a window into the canvas for the widget to scroll
        self.canvas.create_window((5, 5), window=f, anchor="nw")

        yvbar = ttk.Scrollbar(self.canvas, orient='vertical', command=self.canvas.yview)
        xvbar = ttk.Scrollbar(self.canvas, orient='horizontal', command=self.canvas.xview)

        yvbar.pack(side='right', fill='y')
        yvbar.config(command=self.canvas.yview)

        xvbar.pack(side='bottom', fill='x')
        xvbar.config(command=self.canvas.xview)

        self.canvas.config(yscrollcommand=yvbar.set, xscrollcommand=xvbar.set)

        ttk.Label(f, width=20, text='Name: ', font='Arial 12 bold', background="light blue", anchor='w') \
            .grid(column=0, row=1, padx=20, pady=10)
        
        self.name_label = ttk.Label(f, width=40, text='Angelina Jolie', font='Arial 12 bold', foreground="blue",
                                    background="light blue")
        self.name_label.grid(column=1, row=1, padx=20, pady=10)

        self.copy_name_label = ttk.Label(f, width=40, text='', font='Arial 12 bold', foreground="blue",
                                         background="light blue")
        self.copy_name_label.grid(column=2, row=1, padx=20, pady=10)

        copy_button = tk.Button(f, text="Copy", command=self.copy_name)
        copy_button.grid(column=3, row=1, padx=20, pady=10)
        self.root.mainloop()

    def _bound_to_mousewheel(self, event):
        self.canvas.bind_all("<MouseWheel>", self._on_mousewheel)

    def _unbound_to_mousewheel(self, event):
        self.canvas.unbind_all("<MouseWheel>")

    def _on_mousewheel(self, event):
        self.canvas.yview_scroll(int(-1 * (event.delta / 120)), "units")

    a = Form()
    a.form()
