QPointer: add a static assertion to help the user when using a wrong template type
Sometimes people mistype QPointer<Foo *> when they actually must use QPointer<Foo>, add a static assertion for an improved error message (rather than the usual weird template mess). Change-Id: Ic77e3e752ac1906b94f3432eaededf0f7a2737be Reviewed-by: Marc Mutz <>
