我想寫一個基本tkinter的例子,將顯示一個框架延伸框。此時下面的代碼將只打印最終結果,而不顯示框的移動。如何修復代碼,以便隨着時間的推移使用類似移動的代碼,以便隨着時間的推移修改形狀?動畫Tkinter
from tkinter import Tk, Canvas, Frame, BOTH
from time import sleep
class Example(Frame):
def __init__(self, parent):
Frame.__init__(self, parent)
self.parent = parent
self.parent.title("Board")
self.pack(fill=BOTH, expand=1)
self.canvas = Canvas(self)
self.ctr = 10
self.initUI()
def initUI(self):
print(self.ctr)
#The first four parameters are the x,y coordinates of the two bounding points.
#The top-left and the bottom-right.
r = self.canvas.create_rectangle((self.ctr * 10), 0, (self.ctr * 10 + 50), 50,
outline="#fb0", fill="#fb0")
'''
canvas.create_rectangle(50, 0, 100, 50,
outline="#f50", fill="#f50")
canvas.create_rectangle(100, 0, 150, 50,
outline="#05f", fill="#05f")
'''
self.canvas.pack(fill=BOTH, expand=1)
if self.ctr > 0:
self.updateUI()
def updateUI(self):
self.ctr -= 1
sleep(1)
self.initUI()
def main():
root = Tk()
root.geometry("400x100+300+300")
ex = Example(root)
root.mainloop()
if __name__ == '__main__':
main()
