An input method (IM) calls the methods in IIMCallbackEx to send keystrokes to the current application and to change the icon that is displayed on the Input Panel button. The IM is given a pointer to the IIMCallbackEx interface by the software-based input panel (SIP) through the IInputMethodEx::RegisterCallbackEx method.

When to Implement

This interface is implemented by the SIP subsystem in the OS.

When to Use

Use this interface to allow the IM to receive user input and pass this data to the SIP.
