Calibre 2.0, Linux, Chinese input method

anavin · 08-23-2014, 02:16 AM

I've come into some problems about Chinese input method under Linux (openSUSE 13.1, to be specific) and managed to deal it with a workaround, here it is:

I couldn't type Chinese on Calibre 2.0... well, on all Qt 5 applications under Linux (e.g. Sigil 7), actually.
After a quick research I found that my input method, gcin, haven't develop a qt5-immodule yet.
So I installed fcitx (another input method), along with its qt5 module (thanks to all volunteers on software.opensuse.org.)
However I still couldn't type Chinese on Calibre, yet I could on Sigil now.
With another quick research I found Calibre use its own Qt5 library with its own plugin directory:

Code:

/opt/calibre/lib/qt_plugins

So I linked the input method plugins directory to Calibre's Qt plugin directory:
(the plugin directory might vary on different distributions with different CPU architectures)

Code:

su -
cd /opt/calibre/lib/qt_plugins
ln -s /usr/lib64/qt5/plugins/platforminputcontexts/ .

And now I can type Chinese on Calibre 2 again.

Update:
It seems I can edit an environment variable to achieve the same result, since reinstalling calibre could wipe out the link I created:

Code:

export QT_PLUGIN_PATH=$QT_PLUGIN_PATH:/usr/lib64/qt5/plugins/

But I'm not sure mixing KDE4/Qt4/Qt5 plugin paths together in one variable is a good idea :P
