how to color a cell in a QTableView

[JeanC]

Got it working thanks
For those interested my code:

in the .h file add:

class Delegate : public QItemDelegate
 {
 Q_OBJECT
 public:
 Delegate(QWidget *parent = 0) : QItemDelegate(parent) {}
 void paint(QPainter *painter, const QStyleOptionViewItem &option,
                const QModelIndex &index) const;
 };

class Delegate : public QItemDelegate
 {
 Q_OBJECT
 public:
 Delegate(QWidget *parent = 0) : QItemDelegate(parent) {}
 void paint(QPainter *painter, const QStyleOptionViewItem &option,
                const QModelIndex &index) const;
 };

To copy to clipboard, switch view to plain text mode 

in the .cpp, in a constructor

table->setItemDelegate(new Delegate);

table->setItemDelegate(new Delegate);

To copy to clipboard, switch view to plain text mode 

and the event:

//---------------------------------------------------
void Delegate::paint(QPainter *painter, const QStyleOptionViewItem &option,
                          const QModelIndex &index) const
{
QString val;
if (qVariantCanConvert<QString>(index.data()))
    val = qVariantValue<QString>(index.data());
if (val == "1")
	{
  painter->fillRect(option.rect, option.palette.highlight());
	}
else
  QItemDelegate::paint(painter, option, index);
}

//---------------------------------------------------
void Delegate::paint(QPainter *painter, const QStyleOptionViewItem &option,
                          const QModelIndex &index) const
{
QString val;
if (qVariantCanConvert<QString>(index.data()))
    val = qVariantValue<QString>(index.data());
if (val == "1")
	{
  painter->fillRect(option.rect, option.palette.highlight());
	}
else
  QItemDelegate::paint(painter, option, index);
}
