How can I set the text widget contents to the value of a variable in Python/Tkinter?

Question

I am writing a program to assist with a trivial part of my job that can be automated. My purpose here is to:

1. Copy and paste a chunk of plain text into a Tkinter text widget

2. Use that pasted chunk of text as the value of a variable so that the variable can have certain characters pulled and returned down the line.

I have a functioning little bit of code. For example, here is my text widget and the lines of code I use to get and print its contents:

textBox = Text(root)

textBox.focus_set()

def get_input():
    print textBox.get(1.0, 'end-1c')

Then I use a button that uses the command get_input. It works when it comes to printing the contents of the widget.

Now that I know how to properly call on the contents and 'get' them, I would like to learn how I can assign those contents (a string) to the value of a variable.

Are you asking how to assign the results of a function call to a variable? Like the_text = textBox.get(...)? – Ardine

Bryan Oakley, yes thats what I want. I need my code to eventually interact with the text i put into the entry field. – Goodfellowship

Answer 1

I think what you want is this. It will delete all the text and then insert a variable.

def set_input(value):
    text.delete(1.0, "END")
    text.insert("END", value)

It is Python 2.x only. Python 3 requires that "END" be END from the Tk namespace.

Insert a variable? What does it mean? – Sternutatory

In the OP's question, he said he wanted to (I think) set the value of the text. This deletes all the text, then inserts the variable, basically overwriting it. – Leicestershire

Still does not make any sense for me. – Sternutatory

Right, so in Tkinter, you can't directly set the value of a text widget, so you have to delete all the text, then insert the text you want to set it to. – Leicestershire

Answer 2

def set_value():
    text.insert("end-1c", value)

OK, so it's a useful answer. However, it's the normal 'style' on Stack Overflow to offer an explanation with your answer - even if this is very brief. – Cadenza
