IInputMethod2 (Windows CE 5.0)
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
| 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. |
| SetIMMActiveContext | Called whenever ImmSetActiveContext is called. The information received identifies the current state of the IME. |
| RegisterCallback2 | Implemented to receive a pointer to an IIMCallback2 interface. An IM uses the IIMCallback2 interface to send keystrokes to applications and to change the icons on the Input Panel button. |
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:
- Select
- GetInfo
- ReceiveSipInfo
- RegisterCallback
