QTreeView grid line color

I am using QTreeView to display expandable table. But the grid is not showing on QTreeView like on QTableView.

I have tried below code in Ui designer for the property styleSheet of treeview

gridline-color: rgba(255, 255, 255, 255);

But still the grid lines are invisible. What could be the issue?


Try this hack:

QTreeView::item { border: 0.5px ; border-style: solid ; border-color: lightgray ;}
