Andreas Kling	bc319d9e88	LibCore: Make CObject reference-counted ... Okay, I've spent a whole day on this now, and it finally kinda works! With this patch, CObject and all of its derived classes are reference counted instead of tree-owned. The previous, Qt-like model was nice and familiar, but ultimately also outdated and difficult to reason about. CObject-derived types should now be stored in RefPtr/NonnullRefPtr and each class can be constructed using the forwarding construct() helper: auto widget = GWidget::construct(parent_widget); Note that construct() simply forwards all arguments to an existing constructor. It is inserted into each class by the C_OBJECT macro, see CObject.h to understand how that works. CObject::delete_later() disappears in this patch, as there is no longer a single logical owner of a CObject.	2019-09-22 00:25:25 +02:00
