Compiling error

[vfernandez]

I'm getting this compiling error but I can't find the problem. Any ideas?

You can't copy a QObject - and this is what you implicit do when you define a QList<QObject>.
You can use a QList<QObject*> or not derive from QObject.

Ok, I've made it not being a QObject and implemented the operator==() and now it works. Thanks.
