Smartgwt listgrid set cursor to pass icon field

I worked on this problem for a long time, but I could not solve it. I have a listgrid with a field type icon. I would like to change the cursor to a “hand” above the icon.

I searched the Internet and saw that there are several solutions. One of them uses addCellOverHandlerto list grid. But I do not understand how you can change the cursor for the specified listgrid field.

this.addCellOverHandler(new CellOverHandler() {

    @Override
    public void onCellOver(CellOverEvent event) {
    // not able to get the field and setCursor()        
    }
});

My field in listgrid is defined as:

ListGridField iconField = new ListGridField("icon");
iconField.setAlign(Alignment.CENTER);
iconField.setType(ListGridFieldType.ICON);
iconField.setIcon("icons/icon.gif");

As someone pointed to the forum, there is a method setCursor()for listgrid, but not just for the field ...

If anyone has a key ... Thanks
