您能帮我吗,我有以下代码:
root = tkinter.Tk()
root.geometry("100x200")
root.resizable(0, 0)
def loop():
print("test")
root.after(1000,loop)
button=Button(root, text="Start Loop", command=loop).place(x=10,y=10)
root.mainloop()
而且我想在某个时候停止由另一个def手动或自动调用的after循环。我们如何才能停止循环?
谢谢您的建议。
采用这种方法的接缝:
var=None #I have given this variable an value
def start_loop():
global var
print("test")
button_start.configure(text="Stop Loop", command=stop_loop)
var = root.after(1000,start_loop) # now the variable has this value
def stop_loop():
button_start.configure(text="Start Loop", command=start_loop)
root.after_cancel(var) # apply the command for this var which is the loop started early
button_start=Button(root, text="Start Loop", command=start_loop)
button_start.place(x=10,y=10)
希望这是正确的方法,我一直都在寻找它!
