You almost had it QTreeView::item should be the one. Bookmark Qt Style Sheets Reference. That whole section is a pretty good read if you are doing this sort of thing

The font of the content of a QTreeView should be styled via the QTreeview itself e.g. QTreeview {font-size: 20pt;} and not via the style of the item

Thanks. I'll try this later and get back to you.

I tried this->setStyleSheet(QString("QTreeView::Item{font: 87 12pt 'Arial Black';}")); in the StandardTreeView with no success. I also tried making the i in "item" lower case like what you've listed. I will peruse the style sheet reference for some hints.

After looking at the stylesheet reference, I tried QTreeView::item::text and QTreeView::item:text and QTreeView::item.text and QTreeView::text with no success.

Actually playing after playing in the designer QTreeView {font: 20pt, 'Arial Black'} works, changing the item font. It looks like the view does render the item even though QTreeView::item {color: red} changes the color on the item

Awesome! Your last comment was the key. Thanks.
