One of the main advantages of the new Win32 IME architecture is that it provides better communication logic between the application and the IME. Following is an example of how an application could be involved with the IME:
In Windows 95 and Windows NT 4.0 or later, one IME unaware application will be supported with one Default IME window and one Default Input Context.
An IME half-aware application will create its own IME window(s), also called an application IME window, using a predefined system IME class, and may or may not handle its own Input Context given to the application.
An IME fully aware application will handle the Input Context by itself and will display any necessary information given by the Input Context not using the IME window.
