Rich text in table view

How to display rich text in table view?

[spirit]

you can try this, a little bit tricky, but works

MyItemDelegate::MyItemDelegate(QObject *object)
	: QItemDelegate(object)
{
	m_label = new QLabel();
	m_label->setTextFormat(Qt::RichText);
}
 
MyItemDelegate::~MultistringsItemDelegate()
{
	delete m_label;
	m_label = 0;
}
 
QWidget *MyItemDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
	Q_UNUSED(option);
	Q_UNUSED(index);
	return new QLineEdit(parent);
}
 
void MyItemDelegate::setModelData(QWidget *editor, QAbstractItemModel *model, const QModelIndex &index) const
{
	QLineEdit *lineEdit = qobject_cast<QLineEdit *>(editor);
	if (!lineEdit)
		return;
	model->setData(index, lineEdit->text());
	model->setData(index, QString("<span style=\" color:#0ff000;\">%1</span>").arg(lineEdit->text()), Qt::DisplayRole);
}
 
void MyItemDelegate::drawDisplay(QPainter *painter, const QStyleOptionViewItem &option, const QRect &rect, const QString &text) const
{
	m_label->setText(text);
	QPalette pal(m_label->palette());
	pal.setColor(QPalette::Active, QPalette::Window, option.state & QStyle::State_Selected ? pal.color(QPalette::Highlight) : pal.color(QPalette::Base));
	m_label->setPalette(pal);
	m_label->resize(option.rect.size());
	QPixmap p = QPixmap::grabWidget(m_label);
	painter->drawPixmap(option.rect, p);	
}

MyItemDelegate::MyItemDelegate(QObject *object)
	: QItemDelegate(object)
{
	m_label = new QLabel();
	m_label->setTextFormat(Qt::RichText);
}

MyItemDelegate::~MultistringsItemDelegate()
{
	delete m_label;
	m_label = 0;
}

QWidget *MyItemDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
	Q_UNUSED(option);
	Q_UNUSED(index);
	return new QLineEdit(parent);
}

void MyItemDelegate::setModelData(QWidget *editor, QAbstractItemModel *model, const QModelIndex &index) const
{
	QLineEdit *lineEdit = qobject_cast<QLineEdit *>(editor);
	if (!lineEdit)
		return;
	model->setData(index, lineEdit->text());
	model->setData(index, QString("<span style=\" color:#0ff000;\">%1</span>").arg(lineEdit->text()), Qt::DisplayRole);
}

void MyItemDelegate::drawDisplay(QPainter *painter, const QStyleOptionViewItem &option, const QRect &rect, const QString &text) const
{
	m_label->setText(text);
	QPalette pal(m_label->palette());
	pal.setColor(QPalette::Active, QPalette::Window, option.state & QStyle::State_Selected ? pal.color(QPalette::Highlight) : pal.color(QPalette::Base));
	m_label->setPalette(pal);
	m_label->resize(option.rect.size());
	QPixmap p = QPixmap::grabWidget(m_label);
	painter->drawPixmap(option.rect, p);	
}

To copy to clipboard, switch view to plain text mode

Or you can take a look at the "similar threads" table on the bottom of the thread page.

thank u so much guys!

you can also make like this

...
void MyItemDelegate::drawDisplay(QPainter *painter, const QStyleOptionViewItem &option, const QRect &rect, const QString &text) const
{
	Q_UNUSED(rect);
	QTextDocument doc;
	doc.setHtml(text);
	doc.drawContents(painter, option.rect);
}
...

{
	Q_UNUSED(rect);
	QTextDocument doc;
	doc.setHtml(text);
	doc.drawContents(painter, option.rect);
}
