Html text bounding rectangle

[bunjee]

/* virtual */ const unsigned int ZeInfoItem::UpdateHeight(const unsigned int width)
{
	QTextDocument document;
	document.setHtml(mTextComponent.getText());
	document.setTextWidth(width);
 
	mHeight = document.size().height();
	return mHeight;
}

/* virtual */ const unsigned int ZeInfoItem::UpdateHeight(const unsigned int width)
{
	QTextDocument document;
	document.setHtml(mTextComponent.getText());
	document.setTextWidth(width);

	mHeight = document.size().height();
	return mHeight;
}

To copy to clipboard, switch view to plain text mode 

Here is a function to retrieve the height of an HTML text bounding rectangle.
Unfortunately it's quite slow, when called repetitively.

Do you have a better solution ?
Thanks.
