Question

I would like to get a cell/row to look like this in a QTableView:

When running Ubuntu, the QStyledItemDelegate works for both the QTreeView and the QTableView, but on Windows, it only works on QTreeView, and only if I don’t reimplement the paint method.

So my 2 questions are:

How do I get the QStyledItemDelegate to look like the above image in a QTableView?

How do I get the QStyledItemDelegate to look like the above image when reimplementing paint?

The image beside the text is not neccessary. I am just looking for the styled hover and selection box.
Just in case this is needed, my Qt version is 4.7.2.

I finally figured enough of it out.

What I did not solve is why not overriding QStyledItemDelegate.paint() has a different effect from overriding it like:

def paint(self, painter, option, index):
    QStyledItemDelegate.paint(self, painter, option, index)

but that was not part of my question anyway.

What I did solve is how to get the native appearance when painting manually. Previously, when painting the item, I used:

QApplication.style().drawControl(QStyle.CE_ItemViewItem, option, painter)

which had the issue of not painting the native focus or selection. I had a look at the method signature of QApplication.style().drawControl():

void QStyle::drawControl ( ControlElement element, const QStyleOption * option,
                           QPainter * painter, const QWidget * widget = 0 )

and noticed the widget parameter, and tried passing in a QTreeView. It worked. It does not matter what QTreeView is passed, but it makes the view render natively.

So in the end, rendering a native QTableView is as simple as calling:

QApplication.style().drawControl(QStyle.CE_ItemViewItem, option, painter, QTreeView())

in the QStyledItemDelegate‘s paint method.
