Horizontal Scroll Bars for IDLE

from <a href="http://code.activestate.com/lists/python-list/26878/" rel="nofollow">http://code.activestate.com/lists/python-list/26878/</a>
(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.

<blockquote>
 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, <code>__init__</code> method. Add those lines that have <code>###</code>
 appended to them and VOILA you have it. Unfortunately, the scrollbar
 appears BELOW the row and column information in IDLE 0.5 (sigh).

<pre><code> 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 ###
</code></pre>
 
 Hope this is helpful.

No. IDLE does not have horizontal scrollbars for two reasons:

<ol>
<li>Its text editor has few features.</li>
<li>You shouldn't be writing long lines of code. See the <a href="http://www.python.org/dev/peps/pep-0008/#maximum-line-length" rel="nofollow">Maximum Line Length</a> section of the PEP 8 Style Guide for Python Code </li>
</ol>

I'm using IDLE 2.7.3, Windows 7, and I can scroll horizontally by holding down the center mouse button/scroll wheel, and "dragging" around the cursor like that.

blocks|key|1939770|text|我可能还不是Python专家/专家，但这个问题是一个用户体验/可用性问题。有些人可能会说“是啊，PEP8风格指南……诸如此类”，但如果我的空闲窗口有一定的大小(比方说宽度小)，作为一个用户，我没有理由不能滚动。这仅仅是由于糟糕的设计造成的糟糕的用户体验。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1939771|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I may not be a Python expert/guru yet but this question is a user-experience / usability question more than anything. Some might say "Yeah, PEP 8 style guide... blah blah blah" but if I have the IDLE window a certain size (let's say small width), there's no reason I as a user shouldn't be able to scroll. It's simply poor user-experience as a result of poor design.

No, the text scrolls horizontally based on where the insertion point or selection is.

No, because Python PEPs <a href="http://www.python.org/dev/peps/pep-0008/#maximum-line-length" rel="nofollow">emphasize</a>, that line length should be 79 symbols at most. Most of the people violates this of course.

Horizontal Scroll Bars for IDLE, for Python 3.6.

Thanks to Amber and his/her answer, I've found the way to make it work for Python 3.6.

You have to make some changes in the same class <code>EditorWindow</code>, but now it's located in a different module: "editor.py" at %python%\Lib\idlelib\ (win).

First you have to make a change in the same method <code>__init__</code>. And then create a new method <code>handle_xview</code> for the same class.

Here is the code, you have to add the lines that end with <code>###</code>: 

<pre><code> self.vbar = vbar = Scrollbar(text_frame, name='vbar')
 self.hbar = hbar = Scrollbar(text_frame, orient=HORIZONTAL, name='hbar') ###
 ...
 vbar['command'] = self.handle_yview
 vbar.pack(side=RIGHT, fill=Y)
 text['yscrollcommand'] = vbar.set

 hbar['command'] = self.handle_xview ###
 hbar.pack(side=BOTTOM, fill=X) ###
 text['xscrollcommand'] = hbar.set ###
</code></pre>

And the method:

<pre><code>...
def handle_yview(self, event, *args):
...
...
def handle_xview(self, event, *args): ###
 "Handle Horizontal scrollbar." ###
 self.text.xview(event, *args) ###
 return 'break' ###
...
</code></pre>

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
