How to GET row height in QTreeWidget/QTreeView

Question

I just want to get the row height from a QTreeWidgetItem. I searched a lot but nothing hits.

What I want to do is to resize the wrap widget which contains a QTreeWidget to enable all rows in the tree are visible (or to say, it will be a bottomless expanding widget).

sizeHint will always return -1 since I have never set them.

Answer 1

int QTreeWidget::rowHeight(const QModelIndex& index) const

Should suffice.
