[Qt-interest] Is it possible to write an input method using Qt (QInputContextPlugin)?

[Lipik Contact]

Hello,

I have a web-application that uses predictive auto-complete to ease
text input in complex scripts (online at http://lipik.in). I am
looking to convert it into a native input method, for deployment on
Windows/Linux/Mac desktops.

I could not find any toolkit that abstracts platform dependencies for
IMEs, except Qt's QInputContext modules. Just spent an hour reading
the documentation, but just when I was getting excited, realized that
the plugin deployment documents seem to indicate that this method
might not be what I am looking for.
I understood from the docs that plugin can only be used to add support
for IMEs to Qt apps, rather than building a standalone IME itself,
that would be loaded through the OS and would translate inputs for all
apps, whether QT or not.

Am I correct in this (I am hoping not)? Perhaps there is a way to
create a standalone IMEs, since the existing code presumably wraps
native IM functionality anyway?

I would really appreciate any help - it would not be good if I have to
write as many systems as the platform I have to support.

Thank you
Amit
