IInputMethod::RegisterCallback (Windows Embedded CE 6.0)

1/6/2010

This method is implemented to receive a pointer to an IIMCallback interface. An input method (IM) uses the IIMCallback interface to send keystrokes to applications and to change the icons on the Input Panel button.

Syntax

HRESULT RegisterCallback( 
  IIMCallback* pIMCallback
);

Parameters

• pIMCallback
  Pointer to an IIMCallback interface implemented in the software-based input panel. The IM can call methods on this interface to send information back to the software-based input panel.

Return Value

Return S_OK to indicate success. Return the appropriate HRESULT value to indicate failure.

Remarks

The IIMCallback interface to the software-based input panel is exposed only through this method. The software-based input panel calls this method during the initialization of the IM, along with Select,, GetInfo, and ReceiveSipInfo.
