Deleting QObject?

[HamedMasafi]

Why you are deleting object that inherited from QObject??

Because it has no parent, and failure to manually delete it will lead us to memory leak.

[HamedMasafi]

It can have a parent if the QObject's constructor is called on this line

And about deleting QObjects, from qdoc:

You must not delete the QObject directly if it exists in a different thread than the one currently executing. Use deleteLater() instead, which will cause the event loop to delete the object after all pending events have been delivered to it.
