Hi Stewart,
I guess you could implement an custom event on your subclass of
qx.ui.table.model.remote.
So first define an event like "onRowCountCompleted"
In the handler of function _loadRowCount you could do like this:
_loadRowCount : function(firstRow, lastRow)
{
var clazz = this;
handler = function(result, ex, id)
{
// We got (presumably) valid data. Apply it to the table
clazz._onRowCountLoaded(result);
clazz.fireDataEvent('onRowCountCompleted', result);
};
...
So you should able to add a listener to your table model and easyly check
if e.getData() is 0 ;)
If you need more detailed information, so be free to ask.
Hope, could help!
