Re: emulate desktop multi-windows

[johnf]

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

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

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 :-)

Re: emulate desktop multi-windows

[Jason]

In other words, Django has the ability to generate HTML from the context 
you provide it, which is then rendered by the browser.  It doesn't have the 
ability to manipulate as you want because you need to set up a method for 
the browser to communicate back to the server.

That's what people here are saying.  You have the ability to handle 
requests, process data and return responses with django.  Now you need to 
use browser-side development in order to have your users *consume* and 
*interact* with your Django application.

Re: emulate desktop multi-windows

[Andréas Kühne]

HI John,

Django is a HTML framework - you would need to add the javascript part
yourself - that's just the way it works.

There are several different ways of doing what you want, here are a couple
of examples:
http://www.qooxdoo.org/current/widgetbrowser/
https://www.primefaces.org/showcase/ui/overlay/dialog/basic.xhtml

I wouldn't use qooxdoo, but the dialogs are nice :-)

It's really just a matter of searching google

Look into which JS framework you want to use and then the ui will solve
itself.

Dear Johnf,

You can also take a look at django-jstemplate at 
. From their page:


   A templatetag framework for easier integration of mustache.js
   , dust.js
   , handlebars.js
   , or other JavaScript templates with
   Django templates.


Best regards,
Karol

Re: emulate desktop multi-windows

[johnf]

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

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.

Doesn't opening a new browser window imply using lots of memory?
