[ajax] progress bar

[Leszek Gawron <lg...@mobilebox.pl>]

This question is probably directed to Sylvain: as you are rewriting ajax 
support with dojo library is there a control to display some kind of 
progress bar when performing ajax requests? In fact a simple hourglass 
or "Loading..." floating div would suffice.

Currently, when an Ajax request is posted, the cursor is changed to 
"wait", which changes the mouse cursor to an hour class. Now this isn't 
really visible (especially on FF where it changes only when the mouse 
moves).

It's currently hard-coded, but we can change that. In order for it to be 
easy, here's what I suggest:
- if a "cforms-wait" element is present, then show it when an Ajax 
request takes more than e.g. 0.5 second to answer,
- otherwise change the cursor to an hour class,
- and let advanced users override all this with some JS functions.

That way, you can just provide whatever you want in the "cforms-wait" 
element, with images, absolute positioning, etc, etc.

WDYT?

Sylvain, preparing the Dojo commit :-)
