不能用滚动条适当调整框架的大小，让我们说屏幕的全宽

Question

我的问题是，我不能正确的大小框架，我的程序内容，以全屏宽度或改变它在所有。我只得到一个大的根窗口和一个小窗口锚定它的左上角与我的内容在它。但我希望我的内容能够很长，这可能会去从显示器的另一边到另一边

from tkinter import *
def update_scrollregion(event):
    photoCanvas.configure(scrollregion=photoCanvas.bbox("all"))

root = Tk()
root.geometry("1700x900")   

#i tried to change the width below without success, it doesnt change anything either gets smaller nor bigger
photoFrame = Frame(root, width=250, height=190, bg="#EBEBEB")
photoFrame.grid()
photoFrame.rowconfigure(0, weight=1) 
photoFrame.columnconfigure(0, weight=1) 

photoCanvas = Canvas(photoFrame, bg="#EBEBEB")
photoCanvas.grid(row=0, column=0, sticky="nsew")

canvasFrame = Frame(photoCanvas, bg="#EBEBEB")
photoCanvas.create_window(0, 0, window=canvasFrame, anchor='nw')

txt=Text(canvasFrame, height=2, width=30)
Button(canvasFrame, text="Button1", borderwidth=0, bg="#EBEBEB").grid(row=1, column=1, padx=5, pady=5, sticky="nsew")
txt.insert(INSERT, "imagine a very long text here which should stretch from the left side of my screen to the right side of it")  
txt.grid(row=1, column=2, padx=5, pady=5)

photoScroll = Scrollbar(photoFrame, orient=VERTICAL)
photoScroll.config(command=photoCanvas.yview)
photoCanvas.config(yscrollcommand=photoScroll.set)
photoScroll.grid(row=0, column=1, sticky="ns")

canvasFrame.bind("<Configure>", update_scrollregion)

root.mainloop()```

您需要添加。。root.rowconfigure（0，weight=1）和root.columnconfigure（0，weight=1）并设置photoFrame.grid（sticky=NSEW）

from tkinter import *

def update_scrollregion(event):
    photoCanvas.configure(scrollregion=photoCanvas.bbox("all"))

root = Tk()
root.geometry("1700x900")
root.rowconfigure(0, weight=1)
root.columnconfigure(0, weight=1)

#i tried to change the width below without success, it doesnt change anything either gets smaller nor bigger
photoFrame = Frame(root, width=250, height=190, bg="#EBEBEB")
photoFrame.rowconfigure(0, weight=1)
photoFrame.columnconfigure(0, weight=1)
photoFrame.grid(sticky=NSEW)

photoCanvas = Canvas(photoFrame, bg="#EBEBEB")
photoCanvas.rowconfigure(0, weight=1)
photoCanvas.columnconfigure(0, weight=1)
photoCanvas.grid(row=0, column=0, sticky="nsew")

canvasFrame = Frame(photoCanvas, bg="#EBEBEB")
canvasFrame.rowconfigure(1, weight=1)
canvasFrame.columnconfigure(2, weight=1)
canvasFrame.grid(sticky=NSEW)

photoCanvas.create_window(0, 0, window=canvasFrame, anchor='nw')

# txt = Text(canvasFrame, height=2, width=30)
txt = Text(canvasFrame)
txt.insert(INSERT, "imagine a very long text here which should stretch from the left side of my screen to the right side of it, imagine a very long text here which should stretch from the left side of my screen to the right side of it")
txt.grid(row=1, column=2, padx=5, pady=5, sticky=NSEW)

Button(canvasFrame, text="Button1", borderwidth=0, bg="#EBEBEB").grid(row=1, column=1, padx=5, pady=5, sticky="nsew")

photoScroll = Scrollbar(photoFrame, orient=VERTICAL)
photoScroll.config(command=photoCanvas.yview)
photoCanvas.config(yscrollcommand=photoScroll.set)
photoScroll.grid(row=0, column=1, sticky="ns")

canvasFrame.bind("<Configure>", update_scrollregion)

root.mainloop()
