Question

我正在尝试使用Python 3.4.2和tkinter / ttk创建一个文本编辑器。加载我的文件后，文本将从文件底部插入文本小部件，使文件文本“向后”。首先插入文件的最后一行，最后一行插入。一切都会有所帮助。谢谢。

from tkinter import *
from tkinter import ttk
import os

class Main(Frame):
  def __init__(self, master):
    Frame.__init__(self, master)
    self.grid()
    self.create_widgets()

  def create_widgets(self):
    self.body = Text(self, width=50, height=15)
    self.body.grid(row = 0, column = 0, sticky = W)

    self.save_label = Label(self, text="File to Save to:")
    self.save_label.grid(row = 2, column = 0, sticky = W)

    self.save_entry = ttk.Entry(self)
    self.save_entry.grid(row = 3, column = 0, sticky = W)

    self.save_button = ttk.Button(self, text="Save File", command=self.save)
    self.save_button.grid(row = 4, column = 0, sticky = W)

    self.read_label = Label(self, text="File to Read:")
    self.read_label.grid(row = 2, column = 1, sticky = W)

    self.read_entry = ttk.Entry(self)
    self.read_entry.grid(row = 3, column = 1, sticky = W)

    self.read_button = ttk.Button(self, text="Read File", command=self.read)
    self.read_button.grid(row = 4, column = 1, sticky = W)

    scrollbar = ttk.Scrollbar(root, orient=VERTICAL, command=self.body.yview)
    scrollbar.grid(row = 0, column = int(1), sticky = 'ns')
    self.body.config(yscrollcommand=scrollbar.set)

    self.quit_button = ttk.Button(self, text="Quit", command=self.close)
    self.quit_button.grid(row = 5, column = 0, sticky = W)

  def close(self):
    root.destroy()
    quit()

  def save(self):
    body = self.body.get('0.0', 'end-1c')
    file = self.save_entry.get()

    file = open(file, "w")
    file.write(body)
    file.close()

  def read(self):
    self.body.delete("0.0", END)
    file = self.read_entry.get()

    file = open(file, 'r')
    file_data = file.readlines()

    for i in file_data:
      self.body.insert('1.0', str(i))

    file.close()

root = Tk()
root.title("NotePad")
root.geometry("500x600")
root.attributes("-fullscreen", True)
app = Main(root)

root.mainloop()

您告诉tkinter将每行放在"1.0"。如果您希望将每一行添加到最后，请使用"end"

for i in file_data:
  self.body.insert('end', str(i))

顺便说一下，文本小部件的第一个字符位于"1.0"，而不是"0.0"。虽然"0.0"将如何实现tkinter，但正确的索引是"1.0"。

例如，使用此：

body = self.body.get('1.0', 'end-1c')

......而不是这个：

body = self.body.get('0.0', 'end-1c')

如何更改文件文本在Tkinter Text Widget中的插入顺序？
