[PySide] QAbstractTableModel headerData() Qt.BackgroundRole - Ignored?

[Cristián Maureira-Fredes]

Hello,

Nothing to worry about C++,
if you have a QTableView object, you can just use:

.setStyleSheet("QHeaderView::section{background-color: green;}")

on the object.

For example,
modifying the example:

https://code.qt.io/cgit/pyside/pyside-setup.git/tree/examples/widgets/itemviews/addressbook

Precisely the "addreswidget.py" file, adding the same line
under the declaration "tableView = QTableView()"

Produces:

Cheers


PS: There is a small tutorial regarding stylesheet on the docs:
