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.
#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()
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.
