如何分配热键? [英] how to assign hotkeys?

问题描述

请帮助为顶部条目菜单打开"分配热键.

please help to assign hotkeys to the top entry menu "OPEN".

import tkinter

def fileOpen():
    print('qwerty')

def makeMenu(parent):
    top = tkinter.Menu(parent) 
    parent.config(menu = top)                           

    file = tkinter.Menu(top, tearoff = False)
    file.add_command(label = 'Open...', command = fileOpen, accelerator = 'ctrl+o')
    top.add_cascade(label = 'File', menu = file)

    #top.bind_class(top, '<Control-Key-o>', fileOpen)

root = tkinter.Tk()

makeMenu(root)

root.mainloop()

我需要按CTRL + O"运行函数fileOpen"

I need to by pressing "CTRL + O" runs the function "fileOpen"

推荐答案

您需要:

1. 将 fileOpen 绑定到根窗口 (root) 而不是菜单栏 (top).

1. Bind fileOpen to the root window (root) instead of the menubar (top).

使 fileOpen 接受一个参数，当您按下 Ctrl+o 时，该参数将被发送给它.

Make fileOpen accept an argument, which will be sent to it when you press Ctrl+o.

以下是解决这些问题的脚本版本:

Below is a version of your script that addresses these issues:

import tkinter

######################
def fileOpen(event):
######################
    print('qwerty')

def makeMenu(parent):
    top = tkinter.Menu(parent) 
    parent.config(menu = top)                           

    file = tkinter.Menu(top, tearoff = False)
    file.add_command(label = 'Open...', command = fileOpen, accelerator = 'ctrl+o')
    top.add_cascade(label = 'File', menu = file)


root = tkinter.Tk()

############################################
root.bind_all('<Control-Key-o>', fileOpen)
############################################

makeMenu(root)

root.mainloop()
