使tkinter画布原点居中

Question

在不将配置事件处理程序绑定到画布的情况下，是否可以将可调整大小的tkinter.canvas的原点保持在中心位置？我希望获得与以下python脚本相同的结果，但不使用bind

我找了两个小时后就放弃了。有我错过的小部件选项吗

import tkinter
from PIL import ImageTk

def centerCanvasOrigin(e):
    root.update()
    cnv.scan_dragto(round(cnv.winfo_width()/2), round(cnv.winfo_height()/2), 1)
    
root = tkinter.Tk()
cnv = tkinter.Canvas()
cnv.pack(fill = tkinter.BOTH, expand = 1)
cnv.bind("<Configure>", centerCanvasOrigin)
img = ImageTk.PhotoImage(file="img/image.png")
cnv.create_image(0, 0, image = img)
centerCanvasOrigin(True) #i know, sry about this :)

root.mainloop()

Answer 1

Is it possible to keep the origin of a resizable tkinter.canvas centered without binding a Configure event handler to the canvas?

不，不是
