How to clear/delete the contents of a Tkinter Text widget?
提问by Fahadkalis
I am writing a Python program in TKinteron Ubuntu to import and print
the name of files from particular folder in Textwidget.
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 Textwidget's previous list of
filenames.
我正在TKinterUbuntu 上编写一个 Python 程序，以从小Text部件中的特定文件夹导入和打印文件的名称。它只是将文件名添加到Text小部件中以前的文件名，但我想先清除它，然后添加一个新的文件名列表。但是我正在努力清除Text小部件以前的文件名列表。
Can someone please explain how to clear a Textwidget?
有人可以解释如何清除Text小部件吗？
Screenshoot and coding is giving below:
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()

我通过添加“1.0”来检查我的身边，它开始工作
tex.delete('1.0', END)

According to the tkinterbook the code to clear a text element should be:
根据 tkinterbook 清除文本元素的代码应该是：
text.delete(1.0,END)
This worked for me. source
这对我有用。来源
It's different from clearing an entry element, which is done like this:
它不同于清除一个入口元素，它是这样完成的：
entry.delete(0,END) #note the 0 instead of 1.0
entry.delete(0,END) #注意0而不是1.0

from Tkinter import *
app = Tk()
# Text Widget + Font Size
txt = Text(app, font=('Verdana',8))
txt.pack()
# Delete Button
btn = Button(app, text='Delete', command=lambda: txt.delete(1.0,END))
btn.pack()
app.mainloop()
Here's an example of txt.delete(1.0,END)as mentioned.
这是一个txt.delete(1.0,END)如上所述的例子。
The use of lambdamakes us able to delete the contents without defining an actual function.
的使用lambda使我们能够在不定义实际函数的情况下删除内容。

this works
这有效
import tkinter as tk
inputEdit.delete("1.0",tk.END)

for me "1.0" didn't work, but '0' worked. This is Python 2.7.12, just FYI. Also depends on how you import the module. Here's how:
对我来说，“1.0”不起作用，但“0”起作用。这是 Python 2.7.12，仅供参考。还取决于您如何导入模块。就是这样：
import Tkinter as tk
window = tk.Tk()
textBox = tk.Entry(window)
textBox.pack()
And the following code is called when you need to clear it. In my case there was a button Save that saves the data from the Entry text box and after the button is clicked, the text box is cleared
并在需要清除时调用以下代码。在我的例子中，有一个按钮 Save 保存了 Entry 文本框中的数据，点击按钮后，文本框被清除
textBox.delete('0',tk.END)
