Is there a simple way to confirm/cancel listgrid clicks

[mathias]

Hi, playing around with a feature request we got today.

Basically, i'm wondering if there is any way to cancel clicks on a grid. For example, say i want to throw up a confirmation dialog every time a row is clicked in a grid, and only change the selection in the grid if the user clicks yes in the confirmation dialog.

I tried cancelling the events in clickhandler and selectionchanged handler, but that didn't do much. Is there something else that can be done here?

I got it working with a rowdownhandler and then a selectionchanged handler. For reference code below (and if you have a better way, feel free to point out my mistakes!

        grid.addRowMouseDownHandler(rowMouseDownEvent -> {
            rowMouseDownEvent.cancel();
            SC.ask("Sure?", "Yeah", aBoolean -> {
                if(aBoolean){
                    GWT.log("YEAH, lets do rowclick!! row " + rowMouseDownEvent.getRowNum() + ", col" + rowMouseDownEvent.getColNum());
                    grid.selectSingleRecord(rowMouseDownEvent.getRecord());
                }
            });
        });

grid.addSelectionChangedHandler(selectionEvent -> {
            GWT.log("selection changed!!");
            if (grid.getSelectedRecord() != null) {
                details.showItem(grid.getSelectedRecord());
                showDetailPane();
            }
        });
