http://stackoverflow.com/questions/24294316/how-can-i-make-qooxdoo-virtual-list-scalable
I need to show list of data , at least 1 million rows (Big data , machine
learning). I do not need to show at once , remotetablemodel of qooxdoo
table works fine but instead of table i choose list as design choice.
Below is a test i've made.
//create the model data, 1mil itemsvar rawData = [];for (var i = 0; i
< 1000000; i++) {
rawData[i] = "Item No " + i;}var model = new qx.data.Array(rawData);
//create the listvar list = new qx.ui.list.List(model);this.getRoot().add(list);
I understand the point that it will take long to generate rawdata and
assign it to list. But the problem is after assigning the list , the
virtual list itself is almost non-responsive.
Scrolling is very slow , navigating by down arrow freezes a few secs too.
Qooxdoo virtual infrastructure is suppose to render only visible items if i
understand correctly? But in above test case it is so slow. I expect to
work like remote table model .
Tested with qooxdoo latest 4.0.0 and 3.5.1 , on Chrome 35 stable.
