sorry high_flyer,

i solved my problem,i was trying in wrong direction.
so there is no keyboard plugin is required right now.

but i haven't able to create keyboard plugin, it was giving compile error.
i was doing in this way:
1. i had created one kbdHandler class deriving from QWSKeyboardHandler
2. i had created one kbdDriverPlugin derived from QKbdDriverPlugin class and in this
new class i had re-implemented create function in which i am using kbdHandler .

If anyone have idea how to create keyboard plugin( how to compile etc) then suggest me.
