How i can draw a rect 22x22 to make clickabel && emit a signal to parent QWidget
like a ....

QPixmap pix(22, 22);
pix.fill(normalcolor); ... ?


I tested to put in direct a QToolButton but loop to infinite..... and is a setIndexWidget....




Qt Code: 
  1. void BaseDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
  2. {
  3.     /////////qDebug() << "### index-column   " << index.column();
  4.  
  5.     if (index.column() == 0) { 
  6.         /* not on edit only  flags |= Qt::ItemIsSelectable; */
  7.         QString numer = index.model()->data(index, Qt::DisplayRole).toString();
  8.         QString text = QString("(%1)").arg(numer);
  9.         QToolButton * button1 = new QToolButton(tas);
  10.         button1->setText(text);
  11.         tas->setIndexWidget(index,button1);  
  12.     }  else if (index.column() == 1) {
  13.        /* not on edit only  flags |= Qt::ItemIsSelectable; */
  14.         QString coder = index.model()->data(index, Qt::DisplayRole).toString();
  15.         QStyleOptionViewItem myOption = option;
  16.         myOption.displayAlignment = Qt::AlignLeft | Qt::AlignVCenter;
  17.         myOption.palette.setColor( QPalette::Text , Qt::red );
  18.         drawDisplay(painter, myOption, myOption.rect,coder);
  19.         drawFocus(painter, myOption, myOption.rect);
  20.  
  21.     }
  22.         ...............
  23.  
  24.  
  25. }
  26.  
  27. /* header */
  28.  
  29. class BaseDelegate : public QSqlRelationalDelegate
  30. {
  31.     Q_OBJECT
  32.  
  33. public:
  34.     BaseDelegate( QTableView *ta , QObject *parent );
  35.     void paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const;
  36.     QWidget *createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const;
  37.     void setEditorData(QWidget *editor, const QModelIndex &index) const;
  38.     void setModelData(QWidget *editor, QAbstractItemModel *model, const QModelIndex &index) const;
  39. private slots:
  40. private:
  41.     QTableView *tas;
  42.  
  43. };
