            Bug ID: 479122
           Summary: Konqueror on KF6 can't display PDFs using Okular part
    Classification: Applications
           Product: okular
           Version: 24.01.85
          Platform: Gentoo Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: okular-devel at kde.org
          Reporter: stefano.crocco at alice.it
  Target Milestone: ---

I setup Konqueror so that it embeds PDF files using Okular part instead of
opening them in the Okular application. However, with the KF6 versions of both
Konqueror and Okular, this doesn't work: clicking on a PDF file results in
Okular being launched. This happens because Konqueror uses
KParts::PartLoader::partsForMimeType("application/pdf") and (at least on my
system) the returned list doesn't contain "okularpart", despite Okular being
installed and okularpart.so existing in the system.

I think this is caused by two factors:
- okularpart.so (at least on my system) is installed in /usr/lib64/qt6/plugins,
while other parts (dolphinpart.so, arkpart.so and katepart.so) are installed in
/usr/lib64/qt6/plugins/kf6/parts
- okular_part.json only lists application/vnd.kde.okular-archive as mimetype

After adding "application/pdf" to the list of mimetypes in okular_part.json,
recompiling Okular and moving (actually, linking) okularpart.so to
/usr/lib64/qt6/plugins/kf6/parts made KParts::PartLoader::partsForMimeType find
okularpart correctly.

I think that this problem doesn't only happen for PDFs but also for the other
mimetypes supported by okularpart but not explicitly listed in
okular_part.json.

Note: in the bug report, I chose "Gentoo Packages" as platform: however, since
the official Gentoo repository doesn't currently have packages for the KF6
versions of Okular and Konqueror, I installed them from the Gentoo KDE overlay
(https://github.com/gentoo-mirror/kde.git).
