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

[dictoon]

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:


QHeaderView::section:selected
{
background-color: red;
}
This is what I have now:

7269

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

7270

According to the documentation (http://developer.qt.nokia.com/doc/qt-4.7/stylesheet-reference.html), this ought to be possible:


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.)

Cheers,

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:


#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();
}

displays:
7278
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:


#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.
