Question

I’m building a custom QAbstractItemModel model.

The first column contains icons, the second one – text.

This is the code of the data method:

QVariant data ( const QModelIndex & index, int role = Qt::DisplayRole ) const
{
    if(role != Qt::DisplayRole )
        return QVariant();

    int col = index.column();
    if (col == 0)
    {
        return iconProvider->icon(QFileIconProvider::Folder);
    }
    else if (col == 1)
    {
        return "TEXT";
    }
}

But all I get in the resulting Table View is just text in the second column. There’s no folder icon in the first column.

Am I missing something here?

Qt::DisplayRole is only for text. Add:

if ( role == Qt::DecorationRole ) {
    return iconProvider->icon(QFileIconProvider::Folder);
}
