Show Icons in Header of QTreeView

[blackbubblegum]

Hey there,

I have a QTreeView and reimplemented a QStandardItemModel. For some special columns I want to display icons instead of text. So I rewrote QStandardItemModel::headerData(...). I should return a QVariant created with an Icon at these columns. But the icon is not shown in the QTreeView. Instead the header is empty there.

My code looks like this:



QVariant result = QStandardItemModel::headerData( section,
orientation,
role
);

if (result.toString().compare(QString("Special Column")) == 0)
{
QPixmap pixmap = QPixmap(5, 5);
pixmap.fill(Qt::red);
QIcon icon = QIcon(pixmap);
result.setValue(icon);
}
return result;


I tried it with returning a lot of different Variants (icon, string, pixmap etc.) but nothing except QString works.

Did I mised something?
Do I need to reimplement paint from HeaderView?

Thanks and happy new year to all of you,
bbg

No one, any idea?
Do you need further information?

It seems to work for me, but note that you need to return the icon for DecorationRole instead of DisplayRole.
