Aligning Elements

Hello

Does anyone have a chunk of code from a view that would show me how best to align my form form elements?

I know how to add elements, but my alignment abilities are currently limited to "addBreak," or something like "style: '{position=absolute; margin-left: 25px}'!

It seems like the WebFieldSet object could be useful to name and position labeled controls for, say data entry, but there are not examples of such in the WebDemoApp.

Boy, I am really going to owe you guys a nice demo screencast showing a novice the basics!

Rob

Hi Rob,

I would simply use tables for that. Yes I know, there are that movement
from tables to DIVs, but personally I think this gone to far. And we
have an excellent table support in Aida, why not use it?

A simple example:

   e := WebElement new.
   e table class: #webGrid; width: 200.
   e cell align: #right; add: 'Name: '.
   e newCell addInputFieldAspect: #name for: self observee.
   e newRow.
   e cell align: #right; add: 'Surname: '.
   e newCell addInputFieldAspect: #surname for: self observee.
   ^e

Now you can setup some additional CSS for that table. In above example I
reused default webGrid CSS class for that. Just rename that to something
else and introduce additional css method. Ok, you can even do that
inline by simply send:

        e table style: 'css for that table'

It would be nice to have such visual builder, but developing it is not
simple at all and there are just too many failures of such projects out
there. Therefore I rather work on simplifying programming of web apps
instead of investing into such a risky project.

I hope, once in the future we can even have a book :) In the meantime
please continue asking good questions because that way a material for a
book is being collected.

Well, I make my living out of Aida, so answering to the questions is
simple. Not to mention a good feeling having a community!
