Question

我正在尝试使用Tkinter Text Widget制作动画。我希望它每1秒在Text小部件上编写每个帧。这是我目前的代码：

from tkinter import *

frames = ["-o","--o","---o"]

speed = 1000
def clear():
    text.delete(0.0, END)

def movie(event):
    text.delete(0.0, END)
    for frame in range(len(frames)):
        text.insert(END, frames[frame])
        root.after(speed, clear)

root = Tk()
root.title("Animation")
root.minsize(400,400)
root.maxsize(width=root.winfo_screenwidth()-20, height=root.winfo_screenheight()-20)
text = Text(root, highlightcolor="black", highlightbackground="white",width=400, insertbackground="white", height=400, foreground="white", background="black", font="Courier")
text.pack()
root.bind("<Return>", movie)

但是，此代码的输出是

-o--o---o

而不是：

-o[wait a second][clear]--o[wait a second][clear]---o[wait a second][clear]

我该如何解决这个问题？

我发现了我的问题！ .after（）函数几乎像返回函数一样工作。在那里，当被调用时，当前功能停止。这是我的固定代码：

from tkinter import *
frame = 0
frames = ["-o","--o","---o"]

speed = 1000
def clear():
    text.delete(0.0, END)

def movie(event=""):
    global frame
    if frame < len(frames):
        text.delete(0.0, END)
        text.insert(END,frames[frame])
        frame += 1
        root.after(speed, movie)

def movie1(event):
    global frame
    frame = 0
    movie("<Return>")

root = Tk()
root.title("Animation")
root.minsize(400,400)
root.maxsize(width=root.winfo_screenwidth()-20, height=root.winfo_screenheight()-20)
text = Text(root, highlightcolor="black", highlightbackground="white",width=400, insertbackground="white", height=400, foreground="white", background="black", font="Courier")
text.pack()
root.bind("<Return>", movie)

Tkinter等待功能不起作用
