This interface is implemented by the input method (IM) component. The software-based input panel calls the methods of this interface to notify the IM of state changes and to request action and information from the IM. Because an IM is a callback interface, it is up to the developer to implement the following methods.

Methods

The following table lists methods for IInputMethod.

Method Description

IInputMethod::Select

Implemented to create the windows and image list for the IM.

IInputMethod::Deselect

Implemented to select the IM out of the software-based input panel window and to destroy the IM windows.

IInputMethod::Showing

Implemented to perform any initialization before the software-based input panel window is displayed.

IInputMethod::Hiding

Implemented to perform any saving routines before the software-based input panel is hidden.

IInputMethod::GetInfo

Implemented to return information about the current IM to the operating system.

IInputMethod::ReceiveSipInfo

Implemented to receive information about the size, placement, and docked status of the software-based input panel.

IInputMethod::RegisterCallback

Implemented to receive a pointer to an IIMCallback interface. An IM uses the IIMCallback interface to send keystrokes to applications and to change the icons on the Input Panel button.

IInputMethod::GetImData

Implemented to send data from the current IM to the current application.

IInputMethod::SetImData

Implemented to respond to an application's request to set IM-specific data within the IM.

IInputMethod::UserOptionsDlg

Implemented when the user requests that an IM-specific options dialog box be presented.

Remarks

An IM receives method calls in the following sequence before it is required to render the software-based input panel window space or to respond to user actions:

  1. Select
  2. RegisterCallback
  3. GetInfo
  4. ReceiveSipInfo

Requirements

Header sip.h
Library uuid.lib
Windows Embedded CE Windows CE 2.12 and later
Windows Mobile Windows Mobile Version 5.0 and later
