Collection class
Message 1 in thread
Hi everyone,
What is the most appropriate collection class to store a series of values
(not pointers)? Also, is it safe for a function to return a result which
is typed as one of the collection class, ie., QVector<MyClass> function
(...)?
Thanks,

I guess it would depend on how you wish to access the elements in the
collection. If you haven't already looked the different options are
described at:
http://doc.trolltech.com/3.0/collection.html#collection-classes
My guess is you would be interested in one of:
QValueList,
QValueVector,
QValueStack, or
QMap
As for returning a collection class I don't see why not. If its a large
collection though you might consider using a pointer as otherwise the whole
container has to be copied when the function ends.
