Question

我的目标是创建一个画布，它作为一个bg图像，里面有一个框架，里面包含各种标签（标签的数量可以增长），为了模拟它，我创建了一个更大尺寸的框架而不是画布，但你可以看到，当你使用滚动条时，bg图像也会移动。如何在不移动背景图像的情况下移动画布内的什么？甚至可能吗？

 def pr_onFrameConfigure(canvas):
    '''Reset the scroll region to encompass the inner frame'''
    canvas.configure(scrollregion=canvas.bbox("all"))

from tkinter import *

_F_CassaCenter = Tk()


#Master Frame to hold the canvas and scrollbar
_F_CarrelloMain = LabelFrame(_F_CassaCenter, text = "Window")
_F_CarrelloMain.pack()

#Canvas
_C_Maincanvas = Canvas(_F_CarrelloMain, width = 450, height = 300)
_C_Maincanvas.pack(side="left")
_C_Maincanvas.pack_propagate(False)


#Canvas Background image
bgimage = PhotoImage(file="C:\\Users\\Harry\\Desktop\\bg.png")
_C_Maincanvas.create_image(225,150,image = bgimage)
_C_Maincanvas.image_names()

#ScrollBar
_S_Carrello = Scrollbar(_F_CarrelloMain, orient="vertical", command=_C_Maincanvas.yview)
_S_Carrello.pack(side="left", fill="y")
_C_Maincanvas.configure(yscrollcommand=_S_Carrello.set)


#Inside the canvas
_F_OuterCarrelloInner = Frame(_C_Maincanvas, bg="orange")
_F_OuterCarrelloInner.pack()

_F_CarrelloInner = Frame(_F_OuterCarrelloInner, width = 100, height = 350,bg = "green")
_F_CarrelloInner.pack(padx=10, pady=10)
_F_CarrelloInner.pack_propagate(False)

#Canvas internal window to hold stuff that will grow
_C_Maincanvas.create_window((225, 150), window = _F_OuterCarrelloInner)
_F_OuterCarrelloInner.bind("<Configure>", lambda event, canvas=_C_Maincanvas:     pr_onFrameConfigure(_C_Maincanvas))



_F_CassaCenter.mainloop()

修改

我将此功能附加到滚动条，但它将内框移动到画布右侧

def custom_yview(*args, **kwargs):
    _C_Maincanvas.yview(*args, **kwargs)
    x = _C_Maincanvas.canvasx(225)
    y = _C_Maincanvas.canvasy(150)
    _C_Maincanvas.coords("background", x,y)

tkinter - 带滚动条和bg图像的画布
