Reading and Updating data of the Text box
We can place one text box and one button on the window. On click of the button one fixed string saying welcome will be displayed on the text box. For this the lambda of the button is used to call a function my_upd(). Inside the function my_upd() we kept one line of code.
This will add the string Welcome to text box object t2.
We can modify the script and take user input in t1 text box and then pass the same data to t2 text box on button click. After passing the data we can delete the text ( data ) entered by user in t1 text box. The code inside the function my_upd() will change.
The first line will read the data entered by user and add it to t2 text box. Second line will delete the data from first text box t1.
