Hi,
once again I was wrong.
The issue is triggered according to what you comment in the
listForLevel() function (the one I was talking about sooner)... But what
exactly and why? I'm still searching...

Hello,
Sorry for not being able to get back to you on IRC. I have been
busy with another project of mine at my university for quite some
time now.
If a method was virtual before and is pure virtual now then one
can't call that function as the method is of an abstract class
now in Qt5 (and hence can't be instantiated). Just removing these
function calls won't help either as the classes that derive from
these will also remain an abstract class until these pure virtual
functions are reimplemented in the derived classes.
So the calls to these specific functions will automatically turn
up as errors during the compilation process (thus automatically
highlighting the need to take care of the now pure virtual
function). Can you please explain why then is it needed to use
pragma in these cases?
Regards,
Aroonav.
Apart from what Aroonav said, I'd like to add that if there were
these errors, then they would have appeared at compilation time only.
Since each derived class *needs* to define the function that it's
deriving from the abstract base class.
You are right, the problem wasn't this... I figured out after, that it
was because of the Qt::UserRole that changed in Qt5.
Now I tracked the segmentation fault to
/src/browsers/CollectionTreeItemModelBase.cpp, in
void CollectionTreeItemModelBase::listForLevel(int level,
Collections::QueryMaker * qm, CollectionTreeItem * parent)
It appears that removing the last line (QTimer) removes the fault and
that the slot is never triggered. I cannot go further for now. If you
have any ideas.. please tell.
Cheers!
Olivier
