Support Thumbnails in KDE (Dolphin)
Is your feature request related to a problem? Please describe.
F3D gorgeous thumbnails do not show on KDE. KDE appears to have a custom protocol (ie does not support standard thumbnailers).
See: https://discuss.kde.org/t/3d-file-thumbnailer/4173
Describe the solution you'd like
Write a plugin to supports thumbnails in KDE.
After a quick inspection, a simple KDE thumbnailer is not too complex.
For instance the blend file thumbnailer is composed of 3 files.
Describe alternatives you've considered
Using another file manager :cry:
Contribution
I have no experience in KDE development but if F3D is interested in supporting this features I could probably lend a hand!
That looks surprisingly simple. We should be able to rely on f3d::window::renderToImage and convert the result to the QByteArray.
That'd be nice, but can we ship it ?
In any case, we can create this plugin In Another repo and rely on packager to ship it.
We can even put it in F3D but not enable it in the binary release.
For reference, Arch package containing the thumbnailers : https://archlinux.org/packages/extra/x86_64/kdegraphics-thumbnailers/
There is a dependency on ghostscript for example to generate thumbnails for .ps files.
Should we contribute directly there?
Hum, that is an interesting approach. here is the source code: https://invent.kde.org/graphics/kdegraphics-thumbnailers
We would need to discuss with the maintainers of this project

I've posted there: https://discuss.kde.org/t/trying-to-reach-kdegraphics-thumbnailers-developer/17471
Finally got a clear answer from a dev here: https://invent.kde.org/graphics/kdegraphics-thumbnailers/-/issues/1
TLDR: KDE will move to standard thumbnailer mechanism, as all other file managers.
The mechanism has been implemented and is supposed to arrive with KDE Frameworks 6.6 in September.^1
