TreeView used in Qt Designer New Form dialog?

[Bitruder]

I have a tree model and I want the top level items to look different from those below it. Specifically, the new form dialog in Qt Designer has a tree view with exactly this (see screenshot). How can I replicate this? I've looked through the Qt Designer source code, but I can't pin down what widget that is.

Thanks!

It's a QTreeView or QTreeWidget with a custom delegate that uses QStyle::drawPrimitive() to render the button-like looks of top level items.
