View Full Version : Ext.BorderLayout: collapsible&animate: Performance

2 Mar 2007, 5:36 AM
I modified the organiser example from ext-1.0-alpha2 to use a animated colapsible BorderLayout and use 700 png icons from http://famfamfam.com/lab/icons/silk as image source to test JsonView Performance.

While image selection and scrolling was still very fast, I noticed that the colapse animation, resizing and tabbing became very slow. I tested this with IE7.

If have no idea if this could be tuned or if it's a browser limitation.
