addNotRegex() did work for me, but was just way too slow with any
substantial amount of data (>50 lines or so).
I am using a "brute-force" filter at the moment, something along the
following outline:
this.tableModel = new qx.ui.table.model.Simple();
this.data = [some array holding the data]; // can be multidimensional
var filter = qx.ui.form.TextField();
filter.addListener('input', function(e) {
var searchVal = e.getData().toLowerCase();
if (searchVal == undefined || searchVal == null || searchVal == '') {
return;
}
var dataFiltered = [];
var i, dataStr;
var len = this.data.length;
for (i=0; i<len; i++) {
dataStr = this.data[i][1].toLowerCase(); // filtering on col 1 of a
// 2-dimensional array
if (dataStr.indexOf(searchVal) != -1) {
dataFiltered.push(this.data[i]);
}
}
this.tableModel.setData(dataFiltered);
}, this);
Could be improved, of course (no need to filter all the data again on the
2nd, 3rd, ... character; perhaps a timer based timeout for starting the
filtering). But is faster than I can type for several thousands of lines in
my case.
Your mileage might vary ...
Cheers,
Fritz
