我们可以使用<Lock-KeyPress>和<Lock-KeyRelease>绑定来检查 CAPS 锁定键是打开还是关闭。在下面的示例中,我们将创建两个用户定义的函数“ caps_lock_on()”和“ caps_lock_off()”,它们将捕获 Lock-KeyPress 和 Lock-KeyRelease 的事件并在屏幕上打印状态。
# 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()输出结果
当用户按下 CAPS Lock 时,它将显示其当前状态,无论是 ON 还是 OFF。
