Select all text in a Text widget using Python 3 with tkinter
Tkinter text widgets are used for creating text fields that contain multiline user input. It has many inbuilt functions and methods which can be invoked to perform certain operations on text widgets. In contrast, let us assume that we have written a bunch of context in the text widget and if we want to select all the text, then we can use tag_add(tag, range) to select the text and add tag and tag_configure(tag, options) to style the tag property.
Example
#Import tkinter library
from tkinter import *
#Create an instance of tkinter frame
win = Tk()
#Set the geometry
win.geometry("750x200")
def select_text():
text.tag_add("start", "1.0","end")
text.tag_configure("start",background="black", foreground= "white")
#Create a Text Widget
text= Text(win)
text.insert(INSERT, "Python is an interpreted, high-level and generalpurpose
programming language. Python's design philosophy emphasizes
code readability with its notable use of significant indentation")
text.pack()
#Create a button to select all the text in the text widget
button= Button(win, text= "Select", background= "gray71", command=select_text)
button.pack(pady=20, side= TOP)
win.mainloop()Output
Executing the above code will display a window with a button "Select" which can be used to select all the content written in the text widget.
Now, click the "Select" button to select all the text in the widget.
