Smartgwt ListGrid auto generated selection checkbox column freezing

I am using smartGwt 4.0, ListGrid allows us to add multiple columns with auto generated checkbox selection. I am using below property to get checkboxs for each record in the grid,

listGrid.setSelectionAppearance(SelectionAppearanc e.CHECKBOX);

I have many columns in the ListGrid so it comes with horizontal scrollbar, when i try to scroll to the right side, the selection checkbox column gets scrolled and after verifying mutil column values user has to scroll all the way left to select the record, this is bit annoying, is there a way to freez the checkbox column in ListGrid...?
