);

Parameters

unnamedParam1

[in] dwAction

Notification code. This parameter can have one of the following values.

Value Meaning
NI_CHANGECANDIDATELIST
 An application changed the current selected candidate. The dwIndex parameter specifies an index of a candidate list to be selected and dwValue is not used.
NI_CLOSECANDIDATE
 An application directs the IME to close a candidate list. The dwIndex parameter specifies an index of the list to close, and dwValue is not used. The IME sends a IMN_CLOSECANDIDATE command to the application if it closes the list.
NI_COMPOSITIONSTR
 An application directs the IME to carry out an action on the composition string. The dwIndex parameter can be CPS_CANCEL, CPS_COMPLETE, CPS_CONVERT, or CPS_REVERT.
NI_IMEMENUSELECTED
 An application directs the IME to allow the application to handle the specified menu. The dwIndex parameter specifies the ID of the menu and dwValue is an application-defined value for that menu item.
NI_OPENCANDIDATE
 An application directs the IME to open a candidate list. The dwIndex parameter specifies the index of the list to open, and dwValue is not used. The IME sends a IMN_OPENCANDIDATE command to the application if it opens the list.
NI_SELECTCANDIDATESTR
 An application has selected one of the candidates. The dwIndex parameter specifies an index of a candidate list to be selected. The dwValue parameter specifies an index of a candidate string in the selected candidate list.
NI_SETCANDIDATE_PAGESIZE
 The application changes the page size of a candidate list. The dwIndex parameter specifies the candidate list to be changed and must have a value in the range 0 to 3. The dwValue parameter specifies the new page size.
NI_SETCANDIDATE_PAGESTART
 The application changes the page starting index of a candidate list. The dwIndex parameter specifies the candidate list to be changed and must have a value in the range 0 to 3. The dwValue parameter specifies the new page start index.

[in] dwIndex

Index of a candidate list. Alternatively, if dwAction is NI_COMPOSITIONSTR, this parameter can have one of the following values.

Value Meaning
CPS_CANCEL
 Clear the composition string and set the status to no composition string.
CPS_COMPLETE
 Set the composition string as the result string.
CPS_CONVERT
 Convert the composition string.
CPS_REVERT
 Cancel the current composition string and set the composition string to be the unconverted string.

[in] dwValue

Index of a candidate string. The application can set this parameter or ignore it, depending on the value of the dwAction parameter.
