Won't build now - she's dead, Jim.

For Manjaro, just do 'yay kwin-effects-osdclock'. Too easy ;)

Hi Baltasar,
looks like it no longer compiles in Fedora 31, possibly due to qt5 updates

Hi gzu,
I'm David in fact, but that doesn't really matter ;)
I believe that I have already pushed a fix for the compilation issue you are reporting back in September. Could you please pull the latest version from GitHub and try to build again?

Thanks David, I'll know to check the git repo for changes from now on.

9 +Great effect

Hi Baltasar, thanks for your kind words and for the nice blog post!

9 really nice how it's always on top

pro tip: if you want 12hr time, change line 221 in osdclock.cpp to:

path.addText(0, 55, textFont, t.toString("hh:mm a").remove(6, 3));

note: it doesn't show "am" or "pm", just the time in 12hr

Hi goodtrailer, thanks for suggestion. I don't really maintain the plugin much beyond occasional bug fixes. In the future I'll most probably implement time formatting according to the configured user locale.

(for anyone else who wants 12hr time and is impatient :p)

Hello,
Could not figure out how to make this working on Ubuntu 17. I've managed to build the project, but what to do with generated files:
/usr/lib/plugins/kwin/effects/plugins/libkwin_osdclock.so
/usr/lib/plugins/kwin/effects/configs/kwin_osdclock_config.so
There is no osdclock in Settings->Desktop behavior.
Thanks.

Hi onetuser,

OSD Clock is a KWin effect plugin, so you should see its configuration UI in "Desktop Effects" category. I have just uploaded a screenshot of System Settings application window for you to see what it should look like.

Yes, i do not see it in "Desktop Effects" even after reboot. Are those two files enough? No need to add anything to /usr/share/kwin/effects/ or somewhere or edit some config files?

You are right. There's something wrong with Qt5 environment on Ubuntu 17.
Just do `sudo mv /usr/lib/plugins/kwin /usr/lib/x86_64-linux-gnu/qt5/plugins` and you should be fine.

It worked, thank you!

9 Thanks! I love it. I even use it with Raleway font as on the screenshot.
Scaling, however, doesn't work well on HiDPI displays.

Thanks for the feedback. I know about the HiDPI issue. I've already noticed it on my FHD+ display. I can imagine that it looks much worse in 4K. I'll try to fix it soon.

Hi,
For Fedora I changed the cmake command to
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_LIBDIR=lib64/qt5 ..
Also "src/CMakeFiles/kwin_osdclock_config.dir/build.make" didn't seem to have the full path to org.kde.kwin.Effects.xml.
I edited it to "/usr/share/dbus-1/interfaces/org.kde.kwin.Effects.xml" (in 2 places) before running make.
Thanks,
GZU

Hi GZU,
thanks for explanation.
I should update the build instructions to point out the differences between distributions.
Regarding the interface declaration XML: It's strange. Could you please post the output of 'pkg-config --variable=interfaces_dir dbus-1'?
Thanks

Hi laloch,

running 'pkg-config --variable=interfaces_dir dbus-1' gives no output on Fedora 28.

Cheers

Indeed! On Fedora you need to install dbus-devel package. On Debian/Ubuntu it's libdbus-1-dev. I'll update the README accordingly. Thanks for reporting!

Nice kwin clock, good replacement for beclock (which I used in KDE4).
I had a couple of issues getting it to work in Fedora but nothing I couldn't work around.
Thanks,
GZU

Thanks, you're very kind. I made it for myself years ago when our good old BeClock died along with Plasma 4. They even share some parts of code (specifically the blur effect).
Would you mind sharing the issues you had in Fedora? Or perhaps even better please file a bug report(s) over at GitHub if you think there's something I should fix.
