Help: Linux Environmental Variable

Hello,

I'm curious about 3 environmental variable in linux, how they works, their purposes etc. They are:

XMODIFIERS
GTK_IM_MODULE
QT_IM_MODULE

what really happens when I set them something like:

Code:

export XMODIFIERS=@im=uim

export GTK_IM_MODULE="uim"

export QT_IM_MODULE=uim

what will happen if I set them to something other application that is actually not a IME? Or, if the application doesn't exists?

I need to write my own IME like SCIM or UIM so that I need to know these. Please write with a developer's point of view.

Cheers
J.K Kunil

You might try googling using each of those names. Here's one of the hits I got on the first one:

Google will find more things than you might imagine.

Okey, thanks.

Nice signature anyway :)
