Tkinter Entry widget is used to display a single line text. Using tkinter Entry widget, we can set its value or content by triggering a button. It has mainly two types of operation: insert and delete.
Using the Tkinter Button widget, we will set the content of the Entry widget.
#Import the required libraries from tkinter import * #Create an instance of tkinter frame win= Tk() #Define a function to change the value def change_text(txt): text.delete(0,END) text.insert(0,txt) #Set the geometry of frame win.geometry("600x250") #Create an Entry Widget text= Entry(win) text.pack() #Create a button to change/set the content btn= Button(win,text="Set", command=lambda:change_text("My New Text")) btn.pack(pady=20) win.mainloop()
Running the code will display a window containing a button that will set the value or text of the entry widget.
Now click on the “Set” button to set a new value for Entry Widget.
