如何使用 tkinter Canvas 一次创建多个文本?

How to use tkinter Canvas to create multiple text one time?

例如:

for i in range(10000):
   canvas.create_text(10*i,100,text='test',fill='red')

主要window卡在运行这部分。如何在加载文本时避免它?

你可以使用after()来替换for循环,这样它就不会阻塞tkinter mainloop:

def show_text(n=0):
    # show 20 text in each iteration
    for i in range(20):
        y, x = divmod(n+i, 20)
        canvas.create_text(x*50, y*10, text='test', fill='red', anchor='nw')
    n += 20
    if n < 10000:
        canvas.after(1, show_text, n)

show_text() # start the after() loop
