No se q finalidad persigues con la captura del 'evento' pero en mi caso, creo q seria interesante conocer el 'estado' del teclado. De esta manera si saltamos a un dialogo/ventana al salir podemos restaurar dicho 'estado'.

SipShowIM
This function shows or hides the currently active input panel window. An application must call this function to display the input panel and its current input method.

BOOL SipShowIM(
DWORD dwFlag);
Parameters

dwFlag
[in] Specifies whether to show or hide the current input panel window. It is one of the following flags:
Value Description
SIPF_ON Shows the input panel window.
SIPF_OFF Hides the input panel window.

Return Values

TRUE indicates success. When this function fails, it returns an HRESULT error code.

Remarks

When this function is called, the input panel notifies the input method (IM) of the appropriate action to take, which is whether to adopt a hidden or visible state.

On devices that have a limited display area, an application can call SipShowIM to hide the input panel and increase the display area for output.
