Right, gtk use gtk_im_context_get_preedit_string to get preedit
string.

Yes, Qt use QInputContext, I don't know other UI frameworks.

im-scim.so is written in C++. im-scim-bridge.so is written in C, and
connect to the scim-bridge agent(in C++), scim-bridge will connect to
the usual scim socket.
im-scim-bridge.so and im-scim.so will be loaded in UI applications, so
im-scim-bridge.so can avoid load C++ in gtk apps.
