More specifically: at the end of the session, Wt will delete the
application object. The entire WObject tree that sits below the
WApplication object will be deleted. The reference documentation of
WObject explains this:
A second feature of WObject is that they allow ownership organization
in ownership object trees. When an object is created with another
object as parent, it's ownership is transferred to the parent. If not
deleted explicitly, the child object will be deleted together with the
parent. Child objects may also be deleted manually: they will remove
themselves from their parent in the process.
parent->addWidget(new WText("blah")) inserts the WText (a WObject) in
the child list of the parent (also a WObject), so when the parent is
deleted, the child is deleted too.
Best regards,
Wim.
