Actually this menu is only useful when you want to use a non-default immodule, 
and only qt with the immodule patch have this menu. For standard qt, it just 
use the XIM protocol. Typically user just press "Ctrl+Space" to trigger the 
input method and input Chinese.

I did not fully understand what you are trying to do, since most Qt4 widgets 
already have internal immodule support. If you want some non standard widget 
to accept composited characters input, you should 
implement "inputMethodEvent" and "inputMethodQuery". When I did this a few 
month ago, there was few documents about how to implement "inputMethodQuery", 
so I just copied some code from QLineEdit, and it appears to be working 
properly.
