I hope my reply will be appropriate (maybe I won't explain anything you did
not know, but since I wrote this class, this mail ringed a bell for me).
It looks like QList::append( obj ) tries somewhere to assign a SoutModule
(i.e. module1 = module2), but this assignment operator has not been defined
manually (and is not generated automatically by the compiler since
assigning this way would need to re-define member objects...that have been
declared const, which is not possible by design).
Usually, the solution would be to either:
* find another method from QList that does not require the object to be
* turn these const members as non-const
* define ourself a assignment operator (but it does not seem possible since
there are const members anyway).
I have not read the QList documentation right now, so unless we really do
*not* want SoutModule to be assignable (and I think we have no reason not
to want it), removing the 'const' like Steve did seems sensible.
