IInputMethodExis implemented by the input method (IM) component. The input panel calls the IInputMethodExinterfaces to notify the IM of state changes and to request action and information from the IM. Because an IM is a COM interface, the following methods can be implemented.
| Method | Description |
|---|---|
|
Deselect |
Selects the IM from the Input Panel window and eliminates the IM window. |
|
GetImData |
Sends data from the current IM to the current application. |
|
GetInfo |
Returns information about the current IM to the operating system. |
|
Hiding |
Performs any saving routines before the input panel is hidden. |
|
ReceiveSipInfo |
Receives information about the size, placement, and docked status of the input panel. |
|
RegisterCallback |
Receives a pointer to an IIMCallbackinterface. An IM uses the IIMCallbackinterface to send keystrokes to applications and to change the icons on the InputPanel button. |

|
|
Select |
Creates the windows and image list for the IM. |
|
SetImData |
Responds to an application's request to set IM-specific data within the IM. |
|
Called when ImmSetActiveContextis called. The information identifies the current state of the IME. |
|
|
Showing |
Performs any initialization before the Input Panel window is displayed. |
|
UserOptionsDlg |
Presents the User Optionsdialog box for a specific IM. |
 Note: |
|---|
| Except for SetIMMActiveContextand RegisterCallbackEx, all the IInputMethodExinterface methods are identical to the IInputMethodmethods. |
If a custom IM component is developer, the new component should have the Setup application perform self-registration by calling the DllRegisterServerand DllUnregisterServerfunctions. Implement these functions in the IM server DLL. Optionally, the registry values can be set directly. The input panel Propertiesdialog box does not provide any UI elements for the self-registration service.
