    Default Change focus/selection color for single cell in QTableView

    I have a table that renders a cell background green or red depending on its value. Here's a picture:

    When I select/focus the table row, the green color is lost:

    I would like to keep a greenish color only for the single cell on focus/selection. Perhaps I would make it a slightly darker green color. How would I go about doing this?

    Here is my code that renders the cell green or red:

    Qt Code:
    1. QVariant ExternalDataSourcesTableModel::data(const QModelIndex & index, int32_t role) const
    2. {
    3. ...
    4.  
    5. if (role == Qt::BackgroundRole)
    6. {
    7. if (index.column() == static_cast<int>(Column::STATUS)) {
    8. if (externalDataSource.getStatus(reason) == "OK") {
    9. return QColor(Qt::green);
    10. }
    11. else {
    12. return QColor(Qt::red);
    13. }
    14. }
    15. }
    16.  
    17. ...
    18. }

    You create a QStyledItemDelegate subclass that implements paint() the way you want and then attach it to the column of the view with QAbstractItemView::setItemDelegateForColumn()
