如何清除/删除Tkinter Text小部件的内容?

问题描述

我正在Ubuntu上的TKinter中编写一个Python程序以导入和打印Text小部件中特定文件夹中文件的名称.它只是将文件名添加到Text中的先前filname中小部件，但我想先清除它，然后添加一个新的文件名列表.但我正在努力清除Text小部件的上一个列表文件名.

I am writing a Python program in TKinter on Ubuntu to import and printthe name of files from particular folder in Text widget.It is just adding filenames to the previous filnames in the Textwidget, but I want to clear it first, then add a fresh list of filenames.But I am struggling to clear the Text widget's previous list offilenames.

有人可以解释一下如何清除Text小部件吗?

Can someone please explain how to clear a Text widget?

屏幕截图和编码如下:

import os
from Tkinter import *

def viewFile():
    path = os.path.expanduser("~/python")
    for f in os.listdir(path):
        tex.insert(END, f + "\n")

if __name__ == '__main__':
    root = Tk()

    step= root.attributes('-fullscreen', True)
    step = LabelFrame(root, text="FILE MANAGER", font="Arial 20 bold italic")
    step.grid(row=0, columnspan=7, sticky='W', padx=100, pady=5, ipadx=130, ipady=25)

    Button(step, text="File View", font="Arial 8 bold italic", activebackground=
           "turquoise", width=30, height=5, command=viewFile).grid(row=1, column=2)
    Button(step, text="Quit", font="Arial 8 bold italic", activebackground=
           "turquoise", width=20, height=5, command=root.quit).grid(row=1, column=5)

    tex = Text(master=root)
    scr=Scrollbar(root, orient=VERTICAL, command=tex.yview)
    scr.grid(row=2, column=2, rowspan=15, columnspan=1, sticky=NS)
    tex.grid(row=2, column=1, sticky=W)
    tex.config(yscrollcommand=scr.set, font=('Arial', 8, 'bold', 'italic'))

    root.mainloop()

推荐答案

我只是添加了'1.0'进行检查，

I checked on my side by just adding '1.0' and it start working

tex.delete('1.0', END)
