When building and installing qt6 packages from Gentoo, no example or example sources are installed, and there is no USE-flag which could enable that. Reproducible: Always Steps to Reproduce: 1. emerge dev-qt/qtbase:6 Actual Results: No examples installed. No option to install examples. Expected Results: Available option for installation of examples and example sources. Examples are available in QtCreator when they're properly installed. Without them, "Examples" tab should be empty.

We do not install examples (yet), so no need to worry about files or qtbase remembering a bad path. Looking at other distros (at least those that do not set this to a docdir like we were and there are many), putting this under lib/*qt6/ alongside qt6/bin seems to be the typical choice. For actual source code examples, Qt has opted to not support installing these anymore (QTBUG-86302) so we'd have to doins -r ourselves either way, likely like normal docs unless something expects to find these in the Qt examples dir.

QtCreator expects sources of examples in QT6_EXAMPLESDIR when it making instance of example project. "doins -r" into correct directory works for me.

"doins -r" into correct directory works for me. Thanks, will keep that in mind when I get to that then (won't happen right away, but it's on my TODO to integrate this in the eclass).
Hm, I have USE=examples working fine locally but after trying out Qt Creator I'm kind of having second thoughts about this approach. 1. does not seem to be much point in going through the trouble of *building* examples, all Qt Creator needs is the sources to build them itself -- at best it's some never-really-used standalone demos buried in QT6_EXAMPLESDIR that adds a maintenance/testing cost (plus had to do ugly workarounds given some of them mis-installed in double examples dir) 2. similarly to qt-docs, a user could be interested in a more complete set of examples sources 3. installed examples mismatch with qt-docs given didn't do the USE=doc approach to give the same limited set, this results in a lot of dead examples in Qt Creator Feels may be better off with a qt-examples package (like suggested in bug #669268) or maybe better yet qt-docs[examples] given could re-use logic+USE. Could probably revert the above commit too given there won't be arch-specific data if it is just sources. Before making anything final, may end up packaging qt-creator:6 myself so I can happy with how it turns out.
(In reply to Ionen Wolkens from comment #4) >maybe better yet qt-docs[examples] Yeah, this seems to be working pretty well -- qt creator examples tab is looking complete and things work. Liking this better than per-package. Full qt-docs-6.5.2[examples,html,qch,*] is a good ~600MB installed with 20554 files though.

Docs also provide the example-manifests needed for Qt Creator to find them. Also improve intructions for bumping, albeit it is simpler than it looks and should rarely need updates outside major bumps. Interestingly the formerly gone broken png from qt-docs:5 makes a comeback inside the qtdoc-examples archive.

See bug #881433, turns out probably should not build examples. So old location makes more sense if we are only going to install sources in it. Note does mean qtbase will need to be rebuilt before start using that location though (unused currently).
