Now i use this inside my custom class : Dynamic item sizes.
For that case , it dosen’t scroll to absolute bottom , sometimes it stop at
middle of the list.

qx.Class.define('phwabe.utils.list.InfiniList', {
extend: qx.ui.list.List,
members: {
__deferredCall: null,
__scrollBottom: false,
syncWidget: function(jobs) {
if (jobs.scrollBottom) {
this.scrollToY(1e99)
console.log("bottom")
// return
}
var firstRow = this._layer.getFirstRow();
var rowSize = this._layer.getRowSizes().length;
for (var row = firstRow; row < firstRow + rowSize; row++) {
var widget = this._layer.getRenderedCellWidget(row, 0);
if (widget !== null) {
var height = widget.getSizeHint().height;
this.getPane().getRowConfig().setItemSize(row, height);
}
}
},
_initLayer: function() {
this.base(arguments);
this._layer.addListener("updated", this._onUpdated, this);
},
_onUpdated: function(event) {
if (this.__deferredCall === null) {
this.__deferredCall = new qx.util.DeferredCall(function() {
qx.ui.core.queue.Widget.add(this);
console.log("Updated")
}, this);
}
this.__deferredCall.schedule();
}
}
});
Can i get some advices? doing that _onUpdated also not working well.
