* Examples: C++ style cleanupKai Köhne2022-09-071-10/+11
| | | | | | | | | | | | | Run clang-format on all files. Unify the headers to use the canonical include variants: single class includes instead of #include <QtGui>. Finally, using signals and slots instead of Q_SIGNALS and Q_SLOTS. Pick-to: 6.4 Change-Id: I033dad85a4a25600ec4e3171bede8b98e584cf5d Reviewed-by: Lars Knoll <lars@knoll.priv.no>

* Simplify and fix spectrum build structureKai Köhne2021-08-021-0/+108
It is not obvious why the example did go to quite a length to make ffpeg a separate dynamic library. Just build it always as a static library. The code is LGPLv2.1, but that is compatible with the BSD-3-Clause license of the example. Also move the actual application out of the sub-app directory into the top level directory. This is much more intuitive to use. Pick-to: 6.2 Change-Id: Ib6173ce21dab78d02190fb0b38c90629b41d26cd Reviewed-by: Qt CI Bot <qt_ci_bot@qt-project.org> Reviewed-by: Lars Knoll <lars.knoll@qt.io>
