我在基于Tkinter的终端界面中遇到了滚动行为问题。我正在使用scrolledtext.ScrolledText小部件来显示输出，我希望实现以下行为：
1.当用户手动向上滚动时，文本区域应该保持在该位置，即使窗口的大小被调整了。
1.如果在用户向上滚动时打印新文本，则文本区域应停留在当前滚动位置，除非用户已经在文本区域的底部，在这种情况下，它应自动向下滚动以显示新内容。
我已经尝试过几种方法，包括yview()和see(tk.END)方法，但我无法得到所需的行为。
下面是我的代码的简化版本：

import tkinter as tk
import tkinter.font as tkFont
from tkinter import scrolledtext

class TerminalApp:
    def __init__(self, root_):
        self.user_input_var = None
        self.root = root_

        self.font = tkFont.Font(family="Courier", size=12)
        self.text_area = scrolledtext.ScrolledText(self.root, wrap=tk.WORD, font=self.font)
        self.text_area.pack(expand=True, fill="both")

        # Create the edit menu
        self.edit_menu = tk.Menu(self.root, tearoff=0)
        self.edit_menu.add_command(label="Copy", command=self.copy_text, accelerator="Ctrl+Shift+C")
        self.edit_menu.add_command(label="Paste", command=self.paste_text, accelerator="Ctrl+Shift+V")

        # Bind right-click event to show the edit menu
        self.text_area.bind("<Button-3>", self.show_edit_menu)

        # Bind keyboard shortcuts
        self.root.bind("<Control-Shift-c>", self.copy_text)
        self.root.bind("<Control-Shift-v>", self.paste_text)
        self.text_area.bind("<Control-Shift-C>", self.copy_text)
        self.text_area.bind("<Control-Shift-V>", self.paste_text)

    def write_output(self, output):
        yview = self.text_area.yview()[1]
        self.text_area.configure(state="normal")
        self.text_area.insert(tk.END, output)
        self.text_area.configure(state="disabled")
        if yview == 1.0:
            self.text_area.see(tk.END)

    def stop(self):

    def print(self, *args, **kwargs):
        text = "".join(map(str, args))
        end = kwargs.get("end", "\n")
        self.write_output(text + end)

            self.root.clipboard_append(selected_text)

    def paste_text(self, event=None):
        clipboard_text = self.root.clipboard_get()
        if clipboard_text:
            self.text_area.insert(tk.INSERT, clipboard_text)

    def input(self, prompt=""):

                            borderwidth=0, selectborderwidth=0, insertborderwidth=0, border=0.0)

            entry.destroy()

        if prompt:
            self.print(prompt, end="")
        yview = self.text_area.yview()[1]
        self.user_input_var = tk.StringVar()
        entry = tk.Entry(self.text_area, textvariable=self.user_input_var, font=self.font, relief=tk.FLAT,
                         borderwidth=0, border=0.0, insertborderwidth=0, selectborderwidth=0)
        entry.pack(side=tk.LEFT, fill="x", padx=0, pady=0, ipady=0, ipadx=0, expand=True)
        self.text_area.window_create(tk.INSERT, padx=0, pady=0, stretch=1, window=entry)
