Adding button to QTableview

Question

I have created one table by using QTableview and QAbstractTableModel . In one of the cells, I want to add one help button in the r

Answer 1

I got the solution .. Old paint method :

void MyDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
 {
     QStyleOptionButton button;
     QRect r = option.rect;//getting the rect of the cell
     int x,y,w,h;
     x = r.left() + r.width() - 30;//the X coordinate
     y = r.top();//the Y coordinate
     w = 30;//button width
     h = 30;//button height
     button.rect = QRect(x,y,w,h);
     button.text = "=^.^=";
     button.state = QStyle::State_Enabled;

     QApplication::style()->drawControl( QStyle::CE_PushButton, &button, painter);
 }

here is the updated paint() method .

void MyDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
 {
         QItemDelegate::paint(painter, option, index);
  if(index.row()==8)//since i have to make it display only at (8,0) position .
 {
  if(index.column()==0)
  {
     QStyleOptionButton button;
     QRect r = option.rect;//getting the rect of the cell
     int x,y,w,h;
     x = r.left() + r.width() - 20;//the X coordinate
     y = r.top();//the Y coordinate
     w = 15;//button width(based on the requirement)
     h = 15;//button height(based on the requirement)
  button.icon= QIcon(QString::fromUtf8("Resources/HelpIcon.png"));
  button.iconSize = QSize(20,20);
     button.rect = QRect(x,y,w,h);
     button.text = "";//no text . since if text will be given then it will push the icon to left side based on the coordinates .
     button.state = QStyle::State_Enabled;

     //QApplication::style()->drawControl( QStyle::CE_PushButton, &button, painter);

  QApplication::style()->drawControl( QStyle::CE_PushButtonLabel, &button, painter);//To make the Button transparent .

  }
  }
}
