Members

  • hWnd
    Handle to the window that uses the input context.

  • fOpen
    Boolean that indicates the present status of the opened or closed IME.

  • cfCompForm
    COMPOSITIONFORM structure used by the IME user interface to create the composition window.

  • cfCandForm[4]
    CANDIDATEFORM structures used by the IME user interface to create the candidate windows. This IMC supports 4 candidate forms.

  • hCompStr
    Handle to the COMPOSITIONSTR structure. This handle is available when there is the composition string.

  • hCandInfo
    Handle to a memory block that contains the CANDIDATEINFO structure and CANDIDATELIST structures. This handle is available when there are the candidate strings.

  • hGuideLine
    Handle to a memory block that contains the GUIDELINE structure. This handle is available when there is the guideline information.

  • hPrivate
    Handle to a memory block used by IME for its private date area.

  • dwNumMsgBuf
    Specifies the umber of messages stored in hMsgBuf.

  • hMsgBuf
    Handle to the memory block that stores the messages. The format of this memory block is:

    All values are double words.

  • fdwInit
    Initialize flag. When IME initializes the members of the INPUTCONTEXT structure, IME must set the bits of the member indicated by this flag. It is a combination of the following values:

    Value Description
    INIT_STATUSWNDPOS Initializes ptStatusWndPos.
    INIT_CONVERSION Initializes fdwConversion.
    INIT_SENTENCE Initializes fdwSentence.
    INIT_LOGFONT Initializes lfFont.
    INIT_COMPFORM Initializes cfCompForm.
    INIT_SOFTKBDPOS Initializes ptSoftKbdPos.
  • dwReserve
