How do I customizing QTreeView header by stylesheet

[graniteDev]

I am trying to style the header of a QTreeView but there is nothing in the style sheet examples page pertaining to the header.

my code

    m_model = new QStandardItemModel(this);
    m_model->setHorizontalHeaderItem(0,new QStandardItem(QString("Key")));
    m_model->setHorizontalHeaderItem(1,new QStandardItem(QString("Value")));
    ui->treeView->setModel(m_model);

    QFile styleSheet = "./style/vmapViewer.qss";
    styleSheet.open(QFile::ReadOnly);
    ui->treeView->setStyleSheet(styleSheet.readAll());
    styleSheet.close();

my style sheet

QWidget {
    background-color: #2D3D46;
}

QTreeView {
    alternate-background-color: #171E22;
}
QTreeView::branch {
    color: #fff;
}
QHeaderView {
    color: #fff;
    background-color: #000;
}

but as you can see, the headers are still white, along with the text

OK....then does anyone know how to find all the style sheet options for a particular object?

Headers are implemented via QHeaderView class so you need to style that, not QTreeView. See here for an example and here for a list of supported sub-controls and pseudo states.
