Review request for KDE Frameworks and Christoph Feck.


Repository: kwidgetsaddons


Description
-------

While the layout of the tooltip sets the tooltip as parent of the content widget, we don't really need to take ownership of it. We can just restore the old parent once we are done.
This prevents a double delete crash if someone (by accident) deletes first the tooltip and then the content.
