QTreeView, how to call an action when mouse hovers over a row?
I am using C++ Qt5. Currently I have a QStandardItemModel being displayed as a QTreeView with multiple rows and columns. I am aware of using setStyleSheet(), but that just seems to change the color of the row. What I'm looking for is when the mouse hovers over a row, a function is called which I can then use to manipulate my game.

Could you explain me better, what data do you need from the row or do you only want that function to be called when you change rows?

I'm looking for a unique id from each row/col and as I hover over the row/col, a function is called with the unique id from the row & col.

you could give more detail about the ID besides providing a Minimal, Complete, and Verifiable example, to track the hover you could use the mouseMoveEvent method of QTreeView or the editorEvent on a delegate. Your current question is partly clear, but partly misleading, so we need more details.

I agree with @eyllanesc, I would overloadmouseMoveEvent(). May be, it's worth to mentionQTreeView::indexAt()for this which Returns the model index of the item at the viewport coordinates point.

You can use delegate (http://doc.qt.io/qt-5/qtwidgets-itemviews-stardelegate-example.html) and QStyle::State_MouseOver to check if mouse over a row.
You should override paint method.
void paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const {
if(index.row() == 2 && (option.state & QStyle::State_MouseOver)) {
painter->fillRect(option.rect, Qt::blue);
} else {
QStyledItemDelegate::paint(painter, option, index);
}
}
