Hello List,
Well I know about the framework fur Javascript library in Lazarus, but I'm
thinking in the past year or so, what will it take to design a gui
application using Lazarus, and make it work like a web app that act the
same
as the desktop version, without any specific components for it.
Then today I found the following link:
http://blogs.gnome.org/alexl/2010/11/23/gtk3-vs-html5/ and it looks like
someone made something like that on GTK3.
The problem is that I do not have the time to do it myself (or I would
have
created at least the start for it), what will it take to create something
like that for Lazarus that is not dependent on the widgets (it will not
care
if it's GTK, Qt, WinAPI etc..), and take also 3rd party components for it
?
You should first answer the question this man asks:
"Now, I want to know, Is this useful?"
The answer IMHO is: no.
Each and every GUI or user action/change/whatnot will result in a request
from the browser to the webserver (with corresponding result sent back), and
will cause a lot of traffic.
I did not want to use it on the server side but on client side. The server
side should be contacted only when there is a requirement and not for
everything.
Unless they plan on translating the whole of GTK3 to Javascript, I don't see
how you can do that ? How to create a hover effect, tooltips, whatnot,
whenever the mouse moves ? What to do when a user clicks a button ?
All GUI/business logic - of necessity - would reside on the server ?
(unless I'm missing something fundamental, of course)
While this is fine and doable for small apps, it is not scalable at all. If
100 users use your system, it will crash under the load (if not earlier).
More to the point would be the morfik approach:
- Design and code your app as you do now.
- Translate the lot to Javascript+HTML+CSS
Because then, the browser does all the GUI work, and only when necessary
(get
data from server or store data on server) does the server get a request.
I am building all blocks for the latter approach, but it is slow progress.
Is that what the fpWeb will do at the end ?
fpweb will be used to do the server part, yes.
Michael.
