Adding scroll bar to text box in Tkinter Python

[manojkowshik]

Hi Guys,

I'm new to Python. And I'm preparing a GUI in Python and I need to add scroll bar to the Text box. And I'm using 'Tkinter GRID' manager for this. Attached is the image of text box what I need.
I'm getting very large text box if I add a Scroll Bar into it. Below is the code what I have tried,
Please any body help me.

TextBox1 = Entry(resultFrame)
datFileText.grid(row=2, column=0, padx=20, ipadx=200, ipady=40)
scrollBar1 = ScrolledText(TextBox1 )
scrollBar1.grid(sticky=E)

Thanks in advance
Manoj

You don't show what datFileText is in the code you posted. Below is a Tkinter application with a Tkinter.Text widget and scrollbars. The ScrolledText module in Python 2.7 uses the same constructor as Tkinter.Text.

A Tkinter.Entry widget can only be scrolled horizontally. It takes some extra work to setup. The New Mexico Tech Tkinter 8.4 reference can show you how.

It's much easier if you add the Pmw extension and use the ScrolledText widget from Pmw. http://www.ittc.ku.edu/~niehaus/clas.../scrolltext.py
