KListViews can do it, too.  Just do something like this:

QString MyListViewItem::key(int column, bool ascending)
{
t = text(col);

// pad numbers for some user-friendly sorting
QRegExp re("[^\\d](\\d+)");
int location = t.length();
do
{
	location = t.findRev(re, location - t.length() - 1);
	if(location != -1)
	{
		QString numberPart = *re.capturedTexts().at(1);
		t.replace(location + 1, numberPart.length(), numberPart.rightJustify(500, 
'0'));
	}
} while(location != -1);

// if it starts with a number pad the number with zeros
QRegExp re2("^(\\d*)(.*)");
if(-1 != re2.search(t))
{
	QString numberPart = *re2.capturedTexts().at(1);
	t = *re2.capturedTexts().at(2);
	if(!numberPart.isEmpty()) t.prepend(numberPart.rightJustify(500, '0'));
}

return t;
}
