QTableView header invisible

[caduel]

well, without your code... just a guess. Do you check roles in headerData()?

I assume your setting columnCount? Heres a snippet from my model that works:

int TableDetailModel::columnCount(const QModelIndex &parent) const
{
    Q_UNUSED(parent);
    return 2;
}
 
QVariant TableDetailModel::headerData(int section, Qt::Orientation orientation, int role) const
{
    if (role != Qt::DisplayRole)
        return QVariant();
 
    if (orientation == Qt::Horizontal) {
        switch (section) {
            case 0:
                return tr("Id");
 
            case 1:
                return tr("Description");
 
            default:
                return "Unknown!";
        }
    }
    return QVariant();
}

int TableDetailModel::columnCount(const QModelIndex &parent) const
{
    Q_UNUSED(parent);
    return 2;
}

QVariant TableDetailModel::headerData(int section, Qt::Orientation orientation, int role) const
{
    if (role != Qt::DisplayRole)
        return QVariant();
    
    if (orientation == Qt::Horizontal) {
        switch (section) {
            case 0:
                return tr("Id");
                
            case 1:
                return tr("Description");
                
            default:
                return "Unknown!";
        }
    }
    return QVariant();
}

Yes I had ::columnCount and ::headerData. But, I was missing the following from ::headerData

if (role != Qt::DisplayRole)
    return QVariant();

if (role != Qt::DisplayRole)
    return QVariant();

Silly mistake on my part. But you're reply helped me figure out what was missing. The headers are showing up with this snippet in place

thanks!

Hi, thanks for your post. I have the same situation. But I wanna hide the column header. I tried many ways, but there's still an empty header (row 0). I can remove all headers or just row header (column 0) like you do. Could you help me out? Thanks in advance.

Hi, could anybody please help me create a table without row-header (row 0). It'd look like this:

Row1|data-1|data-2
Row2|data-3|data-3

data-x is editable while Row1/row2 is not (it's header-like). I tried many ways but still not able to do so.

Thanks.

Have you tried view->horizontalHeader()->hide() or is that not what your looking for?

Great! It's exactly what I'm looking for! Thank you so much!
