How to show the status of CAPS Lock Key in tkinter?
tkinterpythongui-programming
We can use the <Lock-KeyPress> and <Lock-KeyRelease> bindings to check if the CAPS Lock Key is ON or off. In the following example, we will create two user-defined functions "caps_lock_on()" and "caps_lock_off()" which will capture the event of Lock-KeyPress and Lock-KeyRelease and print the status on the screen.
示例
# Import required libraries
from tkinter import *
from tkinter import ttk
# Create an instance of tkinter frame
win = Tk()
# Define the geometry of the window
win.geometry("700x250")
win.title("CAPS Lock Status")
def caps_lock_on(e):
label_caps.config(text="CAPS Lock is ON")
def caps_lock_off(e):
label_caps.config(text="CAPS Lock is OFF")
label_caps = Label(win, font="Helvetica 15 bold")
label_caps.pack(pady=20)
win.bind("<Lock-KeyPress>", caps_lock_on)
win.bind("<Lock-KeyRelease>", caps_lock_off)
win.mainloop()
输出
When the user presses the CAPS Lock, it will show its current status, whether it is ON or OFF.
