IInputMethod (Windows CE 5.0)

Send Feedback

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.


The following table lists methods for IInputMethod.

Method Description
Select Implemented to create the windows and image list for the IM.
Deselect Implemented to select the IM out of the software-based input panel window and to destroy the IM windows.
Showing Implemented to perform any initialization before the software-based input panel window is displayed.
Hiding Implemented to perform any saving routines before the software-based input panel is hidden.
GetInfo Implemented to return information about the current IM to the operating system.
ReceiveSipInfo Implemented to receive information about the size, placement, and docked status of the software-based input panel.
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.
GetImData Implemented to send data from the current IM to the current application.
SetImData Implemented to respond to an application's request to set IM-specific data within the IM.
UserOptionsDlg Implemented when the user requests that an IM-specific options dialog box be presented.


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. GetInfo
  3. ReceiveSipInfo
  4. RegisterCallback
