Can't style QHeaderView::section:selected in QSS stylesheet

The title says it all: I seem unable to change the background color (or any other property) of a QHeaderView section using the QHeaderView::section:selected selector using Qt 4.7.0. Here's the relevant code:

Code:

---

QHeaderView::section:selected
{
    background-color: red;
}

---

This is what I have now:

Attachment 7269

And this is what I would like to achieve (the selected section is highlighted):

Attachment 7270

According to the documentation, this ought to be possible:

Quote:

---

QHeaderView: Supports the box model. The sections of the header view are styled using the ::section sub control. The section Sub-control supports the :middle, :first, :last, :only-one, :next-selected, :previous-selected, :selected, and :checked pseudo states.

Am I doing it right?

(I couldn't find anything on that subject in the bug database, and I don't have Qt 4.8 handy to check if the behavior is different.)

Try the QHeaderView::section:checked selector... the section headers are like toggling push buttons. The :selected options seem more about formatting tab bars or lists (and nothing to do with selections).

Thanks for the suggestion. Unfortunately using the QHeaderView::section:checked selector has no effect either...

Works fine here:

Code:

---

#include <QtGui>
#include <QtSql>
#include "connection.h"
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    if (!createConnection())
        return 1;
 
    QSqlTableModel model;
    model.setTable("person");
    model.select();
 
    QTableView v;
    v.setStyleSheet( "QHeaderView::section:checked { background-color: green; }");
    v.setModel(&model);
    v.show();
 
    return app.exec();
}

It also works if you apply the style sheet to just the horizontal or vertical header.

No luck here. Here's my test app, derived from yours but without the SQL stuff:

Code:

---

#include <QApplication>
#include <QStringList>
#include <QTreeWidget>
#include <QTreeWidgetItem>
 
int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
 
    QTreeWidget v;
    v.setColumnCount(2);
    v.setStyleSheet("QHeaderView::section:checked { background-color: green } QHeaderView::section:hover { background-color: red }");
    v.setSortingEnabled(true);
    v.addTopLevelItem(new QTreeWidgetItem(&v, QStringList() << "John" << "Doe"));
    v.show();
 
    return app.exec();
}

Setting QHeaderView::section:hover works but setting QHeaderView::section:checked doesn't.

I also tried with QTableView as you did in your test, same problem.

Qt 4.7.0 on Windows Vista.

Thanks,

Linux and Qt 4.7.4: QTreeWidget does not work, QTableWidget does if the table has content.

Highlighting is part of the style... perhaps Windows Vista style does not honour it? I don't have a Vista box hand to try on.

I reported a bug: https://bugreports.qt.nokia.com/browse/QTBUG-23689.

Thanks all for your help.
