<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Hm, at first sight this looks like the loop does essentially nothing - if it finds an empty string in the hash, it puts an empty string with the same key into the hash. Am I overlooking something, or could the entire loop be removed?</pre>

I assumed that since it uses a qvariant that this cannot be guaranteed, in which case the loop overwrites non-string values with an empty string. If we can guarantee it will always be a string, then does it really need to be a qvariant?</pre>

This is wrong.
String, Bool, ByteArray, Char, Date, DateTime, Double, Int, LongLong, StringList, Time, UInt, or ULongLong can be converted to a string with reasonable content
So what this code eventually did was to override few (mostly custom) types with empty strings resp. a dash, ie. at best melt unknown information - what would likely have been a bug since toString() would still return an empty string when this is used. With the patch from "-" -> "" the loop is pointless unless you actively want to destroy information where you explicitly do not know what it is.
QVariant will (likely) be required for Model/View invocation</pre>
