I would see this feature more general like "supporting a paging widget" and in conjunctions with this support for block loading of data. There are already open enhancement issues: http://bugzilla.qooxdoo.org/show_bug.cgi?id=4463 http://bugzilla.qooxdoo.org/show_bug.cgi?id=4554
Feel free to add your comments / requirements or open a separate issue report if the existing don't match. > Secondly does the model dispose of items so that it eventually does not > hold millions of items? If so how is this controlled? That's were block loading comes into play, I guess. For sure, you want to be able to load data in blocks and the model should get populated.
