使用 place（而不是打包）将滚动条与列表框对齐

Question

我想从代码中删除任何“pack”的痕迹，只使用“place”，以便将滚动条定位在列表框附近并沿着列表框的整个高度拉伸它。之前是可以的，后来用pack修改了代码。

现在我想删除所有包并只使用地方

import tkinter as tk   
from tkinter import ttk
from tkinter.scrolledtext import ScrolledText 


window = tk.Tk()
window.geometry("800x800")

frame_title = tk.Frame(window)
frame_title.pack(fill='both', expand=True, pady=5, padx=5)

listbox_title = tk.Listbox(frame_title, selectbackground="#960000", selectforeground="white", bg="white", width = 50, height = 20)
listbox_title.place(x=1, y=1)
listbox_title.configure(font=("Arial", 12))

scrollbar_title = tk.Scrollbar(frame_title)
scrollbar_title.place(x=500, y=1)

scrollbar_title['command'] = listbox_title.yview
listbox_title.config(yscrollcommand=scrollbar_title.set)

listbox_title.bind('<Double-Button-1>') 


text_download = ScrolledText(window, bg="white", width = 50, height = 10)
text_download.place(x=1, y=500)
text_download.configure(font=("Arial", 14))


window.mainloop()

您可以将滚动条直接绑定到列表框或文本小部件，然后当您更改父小部件的大小时它会动态改变。

scroll_bar = tk.Scrollbar(frame_title)
scroll_bar.config(command=listbox_title.yview)
listbox_title.config(yscrollcommand=scroll_bar.set)

## For Verticle Scrollbar ##
scroll_bar.place(in_=listbox_title, relx=1.0, relheight=1.0, bordermode="outside")

## For Horzontal Scrollbar ##
scroll_bar.place(in_=listbox_title, relx=0.0, rely=1.0, relwidth=1.0, bordermode="outside")

然后您可以正常放置列表框。

更新代码：

import tkinter as tk   
from tkinter import ttk
from tkinter.scrolledtext import ScrolledText 


window = tk.Tk()
window.geometry("800x800")

frame_title = tk.Frame(window)
frame_title.pack(fill='both', expand=True, pady=5, padx=5)

listbox_title = tk.Listbox(frame_title, selectbackground="#960000", selectforeground="white", bg="white", width = 50, height = 20)
listbox_title.place(x=1, y=1)
listbox_title.configure(font=("Arial", 12))

## Vertical Scroll Bar ##
scrollbar_title = tk.Scrollbar(frame_title, command=listbox_title.yview, orient="vertical")
listbox_title.config(yscrollcommand=scrollbar_title.set)
scrollbar_title.place(in_=listbox_title, relx=1.0, relheight=1.0, bordermode="outside")

listbox_title.bind('<Double-Button-1>') 


text_download = ScrolledText(window, bg="white", width = 50, height = 10)
text_download.place(x=1, y=500)
text_download.configure(font=("Arial", 14))


window.mainloop()

使用 place（而不是打包）将滚动条与列表框对齐

Align the scrollbar to the listbox using place (and not pack)
