sizeHint based off visible text

[joshuajcarson]

I've searched the forums for sizeHint, but I have been unable to find out to figure out a good sizeHint based off the visible text when displaying html. Currently the sizeHint works wonderfully for all the text in the cell (I just see how many characters are in the QTextDocument), but not so good for just giving a good sizeHint for the characters my user will actually see. Can someone point me in the right direction?

I've found a solution that works. Here is the code

if (qVariantCanConvert<QString>( index.data() ) ) {
	QString htmlText = qVariantValue<QString>(index.data());
	QTextDocument qtd;
	qtd.setHtml(htmlText);
	qtd.setTextWidth(-1);
	QSize toRet;
	toRet.setWidth( ceil( qtd.idealWidth() ) );
	toRet.setHeight( ceil( qtd.size().height() ) );
	return toRet;
} else {
	return QItemDelegate::sizeHint(option, index);
}

if (qVariantCanConvert<QString>( index.data() ) ) {
	QString htmlText = qVariantValue<QString>(index.data());
	QTextDocument qtd;
	qtd.setHtml(htmlText);
	qtd.setTextWidth(-1);
	QSize toRet;
	toRet.setWidth( ceil( qtd.idealWidth() ) );
	toRet.setHeight( ceil( qtd.size().height() ) );
	return toRet;
} else {
	return QItemDelegate::sizeHint(option, index);
}

To copy to clipboard, switch view to plain text mode 

I'm sure there might be a better way, but this seems to work. The QTextDocument gives back a QSizeF, which means it might round down when it should be rounding up all the time. If someone knows of a better way to do this, I'm all ears.
