Re: Portlet Drag and Drop

Hi Rich,

Yes, we are using aria to communication drag and drop functionality. We are using the 'grab' state on items that can be moved and 'dropeffect' state on elements that are valid drop targets. We are also using 'selected' and 'activedescendent' to communicate which item has focus.

Colin,

Scratch the last note. Have you implemented aria drag/drop in the imagegallery tool. I can't see it from the example? It is not clear from looking at the source. It would be nice to know if an image in the gallery is draggable. We are looking for real world test cases for ATs.

Portlet Drag and Drop
<ecblank.gif><ecblank.gif>

Hi,

I know there has been some conversation about the best user experience  
for reordering portlets. I thought it would be useful if I built an  
example to show the alternate user experience.

You can see the new experience here: http://build.fluidproject.org/sakai-imagegallery-tool/sample-code/reorderer/portal/portalWithAvatarClone.html
and the original experience here: http://build.fluidproject.org/sakai-imagegallery-tool/sample-code/reorderer/portal/portal.html

One of the problems with the new example is that it also showcases one  
of our evil bugs. :)  The bug is that the drop target shows up  
somewhere but the portlet drops elsewhere.
http://issues.fluidproject.org/browse/FLUID-407  It's quite a tricky  
little bug from a technical standpoint because the underlying problem  
is that we are getting browser events in the wrong order.  We have a  
strategy for working around this issue but it is quite complex and  
will take a while to implement.
