Hello,I've stumbled upon QPixmap having operator=(QPixmap&&) but missing QPixmap(QPixmap&&), however it seems like there are a lot of Qt classes in the same situation, for example:

Is there any good reason for these classes to not have move constructor, or is it just an unfortunate omission?
Because the implementation of a move constructor for those classes requires the private class to be defined in the public header, but all those classes are pimpl'd, so by definition you don't have that private class available.
Cf. the "Move ctors for q_declare_shared types" thread we had some time ago, and https://codereview.qt-project.org/#/c/115213/ .
