Python 中的移位和大写锁定状态 [英] Status of shift and caps lock in Python

问题描述

我正在使用 Python 2.5 编写 TkInter 应用程序，我需要找出大写锁定和换档键的状态(真或假).我已经在网上搜索了所有但找不到解决方案.

I'm writing a TkInter application using Python 2.5 and I need to find out the status of the caps lock and shift keys (either true or false). I've searched all over the net but cant find a solution.

推荐答案

Tkinter 中的键盘事件可能很棘手.

Keyboard events in Tkinter can be tricky.

我建议您按顺序查看以下内容:

I suggest you have a look at the following, in order:

• http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm
• http://infohost.nmt.edu/tcc/help/pubs/tkinter/events.html(阅读关于事件的整章)
• http://www.faqts.com/knowledge_base/view.phtml/aid/4281

• http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm
• http://infohost.nmt.edu/tcc/help/pubs/tkinter/events.html (read the whole chapter on events)
• http://www.faqts.com/knowledge_base/view.phtml/aid/4281

这是一个显示键码和状态事件参数值的程序.您可以使用它进行实验.点击窗口，然后敲击键盘.

Here is a program that displays the value of the keycode and state event parameters. You can use this to experiment. Click in the window, then hit the keyboard.

from Tkinter import *
root = Tk()

def key(event):
    print "Keycode:", event.keycode, "State:", event.state

def callback(event):
    frame.focus_set()
    print "clicked at", event.x, event.y

frame = Frame(root, width=100, height=100)
frame.bind("<Key>", key)
frame.bind("<Button-1>", callback)
frame.pack()

root.mainloop()
