How to get Icons in QTableWidgetItem to take up the whole item space

Posted something about this earlier... but it kinda got lost in the posts... so im posing the question again with a better title haha.

i have written a custom item delegate... but it doesnt seem to work

Code:

---

class MyItemDelegate: public QItemDelegate
{
public:
   MyItemDelegate(QObject* pParent = 0) : QItemDelegate(pParent)
   {
   }
   void MyItemDelegate::paint(QPainter* painter, const QStyleOptionViewItem& option, const QModelIndex& index) const
   {
      QIcon icon = qvariant_cast<QIcon>(index.data(Qt::DecorationRole));
      drawBackground(painter, option, index);
      drawDecoration(painter, option, option.rect, icon.pixmap(option.rect.size()));
      drawFocus(painter, option, option.rect);
   }
};

---

anyone have any ideas? im real desperate to get this thing working, ive been working on it for days now and i dont know where else to look

seriously though... anyone see anything obvious that i am not doing? im going insane over here... its like im taking crazy pills!

got something to work... not perfect, but the icon will now keep aspect ration in the item. enjoy!!!

#include <QStyledItemDelegate>
#include <QPainter>
 
class ItemDelegate : public QStyledItemDelegate
{
public:
    enum ItemDataRole { SubTextRole = Qt::UserRole + 100 };
 
    ItemDelegate(QObject *parent = 0) : QStyledItemDelegate(parent) {}
    QSize sizeHint(const QStyleOptionViewItem &option, const QModelIndex &index) const;
    void paint(QPainter *p, const QStyleOptionViewItem &option, const QModelIndex &index) const;
};
 
QSize ItemDelegate::sizeHint(const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    QIcon icon = qvariant_cast<QIcon>(index.data(Qt::DecorationRole));
    QString line1 = index.data(Qt::DisplayRole).toString();
    //QString line2 = index.data(SubTextRole).toString();
 
    int textW = option.fontMetrics.width(line1);
    QSize iconSize = icon.actualSize(option.decorationSize);
 
    return QSize(iconSize.width() + 4,
                 iconSize.height() + 2 + option.fontMetrics.lineSpacing() * 2 + 4);
}
 
void ItemDelegate::paint(QPainter *p, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    p->save();
 
    QString line1 = index.data(Qt::DisplayRole).toString();
    QString line2 = index.data(SubTextRole).toString();
 
    QStyleOptionViewItemV4 opt(option);
    initStyleOption(&opt, index);
 
    QStyle *style = opt.widget->style();
    style->drawPrimitive(QStyle::PE_PanelItemViewItem, &opt, p, opt.widget);
 
    if (option.state & QStyle::State_Selected)
        p->setPen(QPen(option.palette.brush(QPalette::HighlightedText), 0));
 
    QRect itemRect = option.rect.adjusted(2, 2, -2, -2);
    QRect r = QStyle::alignedRect(opt.direction, Qt::AlignHCenter | Qt::AlignLeft, itemRect.size(), itemRect);
    opt.icon.paint(p, r);
 
    int h = option.fontMetrics.lineSpacing();
    QRect textRect(itemRect.left(), itemRect.bottom() - h, itemRect.width(), h);
 
    p->drawText(textRect, Qt::AlignVCenter | Qt::AlignHCenter, line1);
 
    QColor subTextColor = p->pen().color();
    subTextColor.setAlphaF(.5);
 
    p->restore();
}
