无法使用滚动条正确调整框架的大小，无法说出整个屏幕的宽度

2024-05-18 • 问答

我的问题是我无法正确地将程序内容的框架大小调整为全屏宽度或完全更改。我得到的只是一个大的根窗口，在它的左上方停着一个小窗口，其中包含我的内容。但是我希望我的内容能够很长，可能会从显示的一侧移到另一侧。

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,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,pady=5)

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

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

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

root.mainloop()
