Setting background of QHeaderView using model's headerData() doesn't work

    • 804a18ef0ec4a054778e223c8cec6ee26dec3f76 (qt/qtbase/5.12)

    Description

      QHeaderView does not respect BackgroundRole or DecorationRole as described in the documentation under Appearance: "QHeaderView respects the following item data roles: TextAlignmentRole, DisplayRole, FontRole, DecorationRole, ForegroundRole, and BackgroundRole."

      Setting color or style of fonts (ForegroundRole or FontRole, respectively) in headerData() is working, but BackgroundRole is not respected, either by returning "QVariant(QColor(Qt::blue))" or "QBrush(QColor(Qt::blue))". Likewise, DecorationRole is ignored in headerData().
