Thank you very much - I was about to check out EXTjs along with
DojotoolKit today.
It looks like I might be able to get this done using web tech.

Hi,
Also Dojotoolkit has windows (or actually Dijit does which is part of
Dojotoolkit):

To my knowledge also Kendo UI does have such a window you're looking for.

To get what I want I will have to use a javascript framework - I
understand. But that said, I have been researching several of the
javascript frameworks and they do in fact allow new tabs (using
chrome). Example: google mail will allow multi-pages (actually tabs)
of contacts just with multi clicks on the GMAIL dropdown. But that
wasn't what I was hoping for - I want individual windows/forms that I
can resize, move, Max, Min, etc... So far the only thing I have found
was the electron app I spoke about earlier. The electron framework
allowed windows that can be resized, moved about the screen, and
closed. I am still researching but so far only Electron. BTW the
Electron is really a desktop app using web tools (css, html,
javascript, and nodejs). I'm guessing (mostly from your emails) that
there are javascript frameworks that will allow what I looking for -
I just haven't found it YET!

No John,
I don't think you understand what we are saying :-)
Like I said earlier - Django is a HTML framework - like ALL HTML
framework, it renders the pages you are seeing on the backend and
presents the information to the user. That is per design in the HTML
world. You click on a link and then the server renders a new page
and so on. There is no way to add "windows" in any other way than to
open a new browser. That is the way HTML works.
If you want to add a fancy single page application (which is what
you are suggesting) then the only way to do so is to use a
Javascript framework of some kind. What that does is to add the
ability to do windows and the like - just in the way you want to do
it - and that is still within the "web UI wold". If you look at
things like the google cloud engine interface or gmail or the amazon
AWS interface, that is all done on the web, with a web UI. However
all of those pages REQUIRE javascript to function.
So it is often requested and I am currently working on a single page
application that uses django for the backend, but HTML cannot render
the single page application - that is done in a javascript
framework. So web UI is completely on par with a desktop application
but it requires more components that you are willing to use :-)

The reason I wanted Django was to insure that the data is valid
(using python). When they enter the data and the submit button
is clicked I want to be able to modify the response using python.
So what I'm hearing from the list - is that in general - people
are not using the Django template system. Is that right?
I have been doing a little research and have discovered a couple
of javascript tools that allow multi -
windows/forms/dialogs/frames. But then - like you said - I'm
replacing the Django template system.
It seems that web UI is still not up to the desktop abilities.
That's not good. BTW I was looking at Electron and discovered
that it can easily match the desktop multi-window and it's using
web tech. So I'm guessing it is possible but not often requested.

Hi,
I think you are not thinking this completely through correctly.
Django is a framework used to generate HTML pages. HTML pages
render one page at a time in one webbrowser window. That is the
way HTML works.
You can via javascript do some funky things, like Single page
applications - but then most of the templating engine in django
isn't used. You could create templates on the backend and send
them via ajax to the frontend but that is mainly used for
rendering partial pages and not for complete pages. Also, it
would be really cumbersome to write the code.
If you already have a REST backend, why do you need django at
all? Django isn't the best framework for getting information
from a REST API and then publishing the information. You really
should be looking into running a single page application in
that case...
Django can be used to create a REST backend for the single page
application however.

I have the backend covered with REST. When I try to
google hybrid google comes up with hybrid mobile apps. I
did find fragment.js but I don't see any type of real
information on how to use it. I did find some info on
javascript and multi-windows but here again it looks like
it wants to replace the template system that Django uses.
It just seems to me that this issue must have come up in
the past. There must be a solution provided by Django
without replacing parts of the Django framework????

Hi.
Yes and no. Usually you do SPA, a single page application,
that just talks to backend, Django in this case, using
some means. REST api and JSON data is quite common.
So basically you need only one template that fires up rest
of your interface.
There are though alternative approaches like using hybrid
of JS library to request HTML fragments and render them
using JS. Fragments then are generated using templates.

But doesn't Django provide the template system? Do
you replace the template system with DoyuoToolkit?

Hi,
This actually doesn't have anything to do with
Django, but frontend. Basically you need to pick
some Javascript UI framework that supports
features you're after.
Personally I've only used Dojotoolkit (free,
nicely licensed) and ExtJS (commercial).

Hi,
I have a desktop CRUD application that allows
the same form to be opened many times.
Example: I can open a customer's (A) record in
one window/form and then from the first
window/form (customer A's) open a second or
third window to process customer B or customer
C etc... all without closing any of the
windows/forms. IOW I can have many windows
open at the same time all using the same form
with different customer records.
How can I do this with Django? I would like
to replace the desktop app with a web app
using Django.
