    Default The QAbstractItemModel' data method failed to overwrite background

    I have a QTreeView which has a stylesheet applied to items with "QTreeView::item{background-color:#F7F7F7}". The view has a custom model and in the data method, I change the background of some specific cells like this :
    Qt Code:
    1. if (index.column() == 3 && role == Qt::BackgroundColorRole)
    2. {
    3. return QColor("#F4FF81");
    4. }
    To copy to clipboard, switch view to plain text mode 
    But this is not working to overwrite the value set in stylesheet. Is there anyone who can tell me what I miss? Thanks!!!

    Stylesheets seem to override and ignore the formatting data coming from the model. See this thread for some suggestions and details:

    Either just extend the model to return the other color for the other columns or is a QIdentityProxyModel to supply the "fall back" background color for cells for which the original model didn't provide any.

    Cheers,
