QTableview data display font question

How to change qtableview data display font?

Use QWidget::setFont() or make your model return the desired font for Qt::FontRole.

Use QWidget::setFont() or make your model return the desired font for Qt::FontRole.

jpn, I've set the font using setFont(), but now the cell does not resize automaticly!!! How do I resize a cell acoording to font size? Do you have maybe some example?

[jpn]

What about the other solution?

[MarkoSan]

I have no idea how to achieve that ...

[jpn]

You said you have QTableView so you have a model too, right? QAbstractItemModel::data() returns data for various roles. Qt::FontRole is one of them.

I have:

• class, subclassed from QTableView (my view)
• class, subclassed from QStandardItemModel (my model)
• class, subclassed from QItemDelegate (my delegate)

How do I get to this font role?

[jpn]

QVariant MyCustomModel::data(const QModelIndex& index, int role) const
{
    if (index.isValid() && role == Qt::FontRole)
        return QFont(...);
 
    return QStandardItemModel::data(index, role);
}

QVariant MyCustomModel::data(const QModelIndex& index, int role) const
{
    if (index.isValid() && role == Qt::FontRole)
        return QFont(...);

    return QStandardItemModel::data(index, role);
}

Well, this is my code for data() function:

QVariant CShoppingCartModel::data(const QModelIndex &index, int role) const
{
    if(index.isValid() && role==Qt::EditRole)
        return m_pMerchandizeOrder->orders()->at(index.row()).strDisplayString;
        //QStandardItemModel::data(index, role);
    if(index.isValid() && role==Qt::FontRole)
        return QFont("Courier New", 24, QFont::Bold);
    return QVariant();    // returns invalid record
}

QVariant CShoppingCartModel::data(const QModelIndex &index, int role) const
{
    if(index.isValid() && role==Qt::EditRole)
        return m_pMerchandizeOrder->orders()->at(index.row()).strDisplayString;
        //QStandardItemModel::data(index, role);
    if(index.isValid() && role==Qt::FontRole)
        return QFont("Courier New", 24, QFont::Bold);
    return QVariant();    // returns invalid record
}

To copy to clipboard, switch view to plain text mode 

And the result is still the same, the cell size is not updated. What is still missing?
