static QChar getNextChar ( const QString &  s, int  location  )

inlinestatic

Here is the caller graph for this function:

int naturalCompare	(	const QString &	s1,
		const QString &	s2,
		Qt::CaseSensitivity	cs
	)

Natural number sort, skips spaces.

Examples: 1, 2, 10, 55, 100 01.jpg, 2.jpg, 10.jpg

Note on the algorithm: Only as many characters as necessary are looked at and at most they all are looked at once.

Slower then QString::compare() (of course)
