Override ListGrid Sort(), prefetchData

[igorr2001]

Hi!

I have been using SmartGwt 4.0.
My questions:
1)Can I @Override sort method ListGrid?
2)Can I run prefetchData before fetchData if I need time for prepare date?
3)Can I stop sorting by Server in handler event onSortChanged event if SortEvent event cancel() method is absent ?

I too am curious if there is a way to cancel the SortEvent for the SortChangedHandler (point #3).

listGrid.addSortChangedHandler(new SortChangedHandler() {
        @Override
        public void onSortChanged(SortEvent event) {}
			
    });

No, not really. In general, the framework provides various ways to cancel something *the end user* is doing.

This handler can be triggered by a lot of things, including your own code that has triggered a sort, or internal framework code that has triggered a sort. In those kinds of scenarios cancellation makes no sense, as of course your code or our code assumes the method calls are being obeyed!

Thank you kindly.

Speaking of cancelling something the end user is doing, I am looking for an equivalent handler to addHeaderClickHandler(HeaderClickHandler) for handling the user applying a new sort via the Configure Sort... window. I assume since you can handle the header click events and cancel them that there is a way to similarly handle Configure Sort... change events?
Thanks

I see there is a MultiSortCallback, so perhaps what I am looking for here is to integrate my own header context-menu item that opens the multi-sort dialog and provide's custom callback logic here.

...confirming this provided the capability I needed.
