Python tkinter（复制/粘贴不适用于其他语言）

Question

I found out that whenever i switch the language from english to russian tkinter stops reacting to Ctrl + C , Ctrl + V or Ctrl + X .

It still works when i switch back to english, even if the text is in russian.

I tried all code snippets i could find on stack exchange remotely related to copy-paste topic, adding stuff similar to original code like self.bind('<Control-м>', self.paste) ("м" is the same button in russian as "v" in english), but still nothing works.

Would really appreciate any help/ideas on how to fix it.

Answer 1

from Tkinter import Tk, Entry   

def _onKeyRelease(event):
    ctrl  = (event.state & 0x4) != 0
    if event.keycode==88 and  ctrl and event.keysym.lower() != "x": 
        event.widget.event_generate("<<Cut>>")

    if event.keycode==86 and  ctrl and event.keysym.lower() != "v": 
        event.widget.event_generate("<<Paste>>")

    if event.keycode==67 and  ctrl and event.keysym.lower() != "c":
        event.widget.event_generate("<<Copy>>")


master = Tk()
master.geometry("500x500+1+1")
master.bind_all("<Key>", _onKeyRelease, "+")
Entry(master).pack()
Entry(master).pack()
Entry(master).pack()
master.mainloop()

I did this.

1.First received the current layout language on the advice of here :

def is_ru_lang_keyboard(self):
    u = ctypes.windll.LoadLibrary("user32.dll")
    pf = getattr(u, "GetKeyboardLayout")
    return hex(pf(0)) == '0x4190419'

2. Then I defined the keys() method taking into account the layout, because without a condition in the case of the English layout, the method gave a duplicate string when inserting:

    def keys(event):
        if self.is_ru_lang_keyboard():
            if event.keycode==86:
                event.widget.event_generate("<<Paste>>")
            if event.keycode==67: 
                event.widget.event_generate("<<Copy>>")    
            if event.keycode==88: 
                event.widget.event_generate("<<Cut>>")    
            if event.keycode==65535: 
                event.widget.event_generate("<<Clear>>")
            if event.keycode==65: 
                event.widget.event_generate("<<SelectAll>>")

3.Bound the keys() method of the Entry field to the "Control-KeyPress" event:

self.my_entry.bind("<Control-KeyPress>", keys)

Answer 3

You can use <Key> to check what keycode is used when you press Control-м and then use it to find keysym on page like Tcl/Tk - keysym . Maybe you will have to use <Control-Cyrillic_em>

import tkinter as tk

def copy(event):
    print('copy')

def paste(event):
    print('paste')

def test(event):    
    print('event.char:', event.char)
    print('event.keycode:', event.keycode)
    print('event.keysym:', event.keysym)
    print('---')

root = tk.Tk()

root.bind('<Key>', test)

root.bind('<Control-c>', copy)
root.bind('<Control-v>', paste)
root.bind('<Control-Cyrillic_em>', paste)

root.mainloop()
