Displaying QTextEdit content into QTableView cell

hisoft

Hi,

I have a QTableView associated to QItemDelegate. I reimplemented the createEditor and paint methods :

createEditor() method :
@
QWidget *ModelDelegate::createEditor(QWidget parent,
const QStyleOptionViewItem &/ option */,
const QModelIndex & index) const
{
if (index.column() != 0)
{
QTextEdit * editor = new QTextEdit(parent);
editor->setFixedHeight(150);
return editor;
}
else
return NULL; // First column is not editable
}
@

paint() method :
@
void ModelDelegate::paint(QPainter *painter, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
QStyleOptionViewItemV4 optionV4 = option;
initStyleOption(&optionV4, index);

 QStyle *style = optionV4.widget? optionV4.widget->style() : QApplication::style();

 QTextDocument doc;
 QString value = index.model()->data(index, Qt::DisplayRole).toString();
 doc.setHtml(value);

 // Painting item without text
 optionV4.text = QString();
 style->drawControl(QStyle::CE_ItemViewItem, &optionV4, painter);

 QAbstractTextDocumentLayout::PaintContext ctx;

 // Highlighting text if item is selected
if (optionV4.state & QStyle::State_Selected)
     ctx.palette.setColor(QPalette::Text, optionV4.palette.color(QPalette::Active, QPalette::HighlightedText));
else
    ctx.palette.setColor(QPalette::Text, QColor("white"));

 QRect textRect = style->subElementRect(QStyle::SE_ItemViewItemText, &optionV4);
 painter->save();
 painter->translate(textRect.topLeft());
 painter->setClipRect(textRect.translated(-textRect.topLeft()));
 doc.documentLayout()->draw(painter, ctx);
 painter->restore();

}
@
Now, the problem is that when i edit a cell and insert formatted text with some images, those images are not correctly shown into the cell (instead i’ve a little blank icon).

Any idea ?

Thanks.
