Hello All!
how can I sort QxListItems in a QxList?
Lets say we have a QxList with QxListItem children. My thoughts were:
window.application.main = function() {
var list = new QxList(); list.set({top:50,left:50});
list.add(new QxListItem('Will'));
list.add(new QxListItem('Anna'));
list.add(new QxListItem('Tom'));
list.add(new QxListItem('Diana'));
list.add(new QxListItem('Pete'));
function qxlistitemCompare (a,b) {
var av = a.getLabel();
var bv = b.getLabel();
return av < bv ? -1 : ( av == bv ? 0 : 1 );
}
var btn = new QxButton('Sort'); btn.set({top:50,left:200});
btn.addEventListener('click',function(e){
var items = list.getChildren();
items.sort(qxlistitemCompare);
for(var i=0;i<items.length;i++) {
list.add(items[i]);
}
});
this.add(btn);
this.add(list);
};
The array is sorted correctly but the problem seems to be that re-adding
the items to the list is not enough to enforce a resorting or recreation
of the items.
Any Ideas what I have to do to make it work? 2 Cents are welcome ;-)
try to add a locationY job to the layout queue of each child:
yourListItem.addToLayoutChanges("locationY");
I have not tried it but possible it helps with your problem.

Thank you.
