#34335 — mini browser with python

[Multipart message — attachments visible in raw view] — view raw

Python help.

I can connect to and download a web page,
html code, and save it to a file.  If connected 
to the web, I can change the settings on  KWrite 
to open the file and navigate the page, 
 (just like a browser does).

I want to view the html file without using a browser 
or KWrite as I do now. 

Customer wants a direct connect to a dedicated 
website.  Their clients can be using any 
browser. This gives them a a direct connect to 
a dedicated website for a specific purpose.
  
In other words I need a mini, simple browser; 
something I can build that will open, read and 
display a saved html or the connected url site.

I would appreciate some direction.

What will be the output of this mini browser?  Plain text?  Rendered
graphics?  An audible screen reader?  Something else?

What web standards does this mini browser need to support?  Full HTML5?
Partial HTML?  CSS?  Javascript?  Flash?

How about:

import os.path, webbrowser

webbrowser.open("file://" + os.path.abspath(your_file))

> I would appreciate some direction.

You'd get more useful answers if you'd give some
more context.  For example:

* Which platform?
* Which version of Python?
* Which GUI (if any)?
* What capabilities do you need?  CSS? Javascript?
* Are there any unusual requirement?


Hope this helps,

A few responders have ask for this information. 

Platform can be linux or Windows.
Currently: Linux runs Python 2.7
 and Windows runs 2.6.3; 
Windows can be XP and above.
My program is built with Python and Tkinter
I convert the program using py2exe.

There are no special requirements. 
The client will design around my capabilities.

The html page will simply be a display of data. 

Right now I need some way to display 
15 to 20 lines of html in its own window or 
as part of my screen. 

I am trying to avoid using any commercial
browser. 

GTK has a webkit, and QT has a webkit and 
Suse, wich I use has libwebkitgtk-1_0-0.

All at some time I will have to look at all. 
I thought If someone had done this already 
The learning curve could be lowered.

Thanks for the interest,
jimonlinux

Could you open a shell window and run a text web browser such as Lynx?

That is a possibility but then every machine
will have to have Lynx.  That is not quite
what the customer wants.
  
Also, I can download the site to a file, convert 
the data to text,  then display it in a Text widget. 

I appreciate the help,

Or you can download and work with it in memory.

Using existing html parser.

The complication in displaying html is with placing images and other 
boxed content, including tables, and flowing text around the boxes. If 
the html you want to work with is simple and has a somewhat fixed 
format, you should be able to extract all the info as either text or a 
table and be able to format and place it how you want.

What you are suggesting is what was suggested when this 
project was originally discussed.

However, I was naive about the complications of simply 
viewing a web page. And, making something like this work on 
Linux and Windows.

I've come to the conclusion that processing the data with
a parser and formatting it in a widget is the only way to make it 
work on both platforms.  Parsing the data also gives one the 
ability to produce a module that will work in multiple versions of 
either platform and still keep control of all of the code. 

I appreciate the Help,
