Question

I am using IDLE to learn Python 2.7 on Windows 7.

The Vertical scroll bar works fine but I cannot find
a way to activate the Horizontal scroll bar.

Is there a horizontal scroll bar in Python’s IDLE?

Thanks

Answer 1

Horizontal Scroll Bars for IDLE

from http://code.activestate.com/lists/python-list/26878/
(not my code, found it on this site)
It is dated Wed, 08 Mar 2000

Works for Python 2.6 but I can’t get to work in 2.7. I get an error saying that the file is open some where. For me, the file he is talking about is located in:C:\Python27\ArcGIS10.1\Lib\idlelib It will be different if you do not have the ArcMap program which comes with python and installs it for you.

I finally got around to adding horizontal scroll bars to the IDLE
editor window to help when you get those LONG lines of code. They
changes are rather mionor (4 new lines of code) and were made in the
EditorWindow.py module. To make the changes in IDLE, open
EditorWindow.py and perform a search for ‘vbar’ which is in the
EditorWindow class, __init__ method. Add those lines that have ###
appended to them and VOILA you have it. Unfortunately, the scrollbar
appears BELOW the row and column information in IDLE 0.5 (sigh).

    self.vbar = vbar = Scrollbar(top, name='vbar')
    self.hbar = hbar = Scrollbar(top, orient=HORIZONTAL, name='hbar') ###
    ...
    vbar['command'] = text.yview
    vbar.pack(side=RIGHT, fill=Y)
    hbar['command'] = text.xview        ###
    hbar.pack(side=BOTTOM, fill=X)      ###

    text['yscrollcommand'] = vbar.set
    text['xscrollcommand'] = hbar.set   ###

Hope this is helpful.
