python - Python TKInter：AttributeError：“NoneType”对象没有属性“create_image”

Question

我正在尝试创建 Tkinter GUI，但在尝试将 gif 图像放在画布上时出现属性错误。

canvas_1 = Canvas(width = 800, height = 450, bg = "blue").pack()
gif = PhotoImage(file = "C:\\Users\\Luke\\Desktop\\fb.gif")
canvas_1.create_image(0, 0, image = gif, anchor = NW)

这是我得到的错误

  canvas_1.create_image(0, 0, image = gif, anchor = NW)
AttributeError: 'NoneType' object has no attribute 'create_image'

提前致谢。

Answer 1

在Tkinter，方法.pack和.grid返回None。他们不返回Widget.

修复很简单。将其拆分为 2 行：

canvas_1 = Canvas(width = 800, height = 450, bg = "blue")
canvas_1.pack()
