How to clear/delete the contents of a Tkinter Text widget?
Question:
I am writing a Python program in TKinter
on Ubuntu to import and print
the name of files from particular folder in Text
widget.
It is just adding filenames to the previous filnames in the Text
widget, 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 of
filenames.
Can someone please explain how to clear a Text
widget?
Screenshoot and coding is giving below:
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()
Answers:
I checked on my side by just adding ‘1.0’ and it start working
tex.delete('1.0', END)
you can also try this
According to the tkinterbook the code to clear a text element should be:
text.delete(1.0,END)
This worked for me. source
It’s different from clearing an entry element, which is done like this:
entry.delete(0,END) #note the 0 instead of 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.
The use of lambda
makes us able to delete the contents without defining an actual function.
this works
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:
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
textBox.delete('0',tk.END)
I think this:
text.delete("1.0", tkinter.END)
Or if you did from tkinter import *
text.delete("1.0", END)
That should work
A lot of answers ask you to use END
, but if that’s not working for you, try:
text.delete("1.0", "end-1c")
text.delete(0, END)
This deletes everything inside the text box
