I had you in my To: list & gtk-list as cc:

Yes its a static variable in gtkimmulticontext.c, but in a text widget
like GtkEntry (or GtkTextView)
GtkEntry->im_context->context_id = global_context_id (static variable char*)
So when a gtk_im_multicontext_new() is allocated to
gtkentry->im_context, its takes the context_id from this static
variable.

I have changed this variable by assigning it my module name (as
suggested in prev mail) statically before compiling.

Yes the module code takes care of  initialisation.

That might work, havent tried.

Yes, It changes the input method for all applications if the hardcore
change is made in the gtkimmulticontext.c, but if you assign it at
runtime on right click, it changes only for the particular app.
The procedure that i described also adds "myinputmethod" in the right
button menu. So it can be choosen runtime if not assigned as default.
