UFT :: Unable to select checkboxes from SWFTREEVIEW

Question

I want to select check boxes which are in SwfTreeView. I tried to get getitem and getitemcount and it is returning 0. Below is the hierarchy of object SwfWindow().SwfWindow().SwfTreeView("swfname:=treeListVarTypes")

Please suggest possible ways to select checkboxes from SwfTreeView. Check boxes are like Systematic is parent and SPREAD, NON SPREAD are their childs.
