This structure holds the context information for IME input.

Syntax

typedef struct tagINPUTCONTEXT{
  HWND hWnd;
  BOOL fOpen;
  HWND hwndImeInUse; 
  POINT ptStatusWndPos;
  POINT ptSoftKbdPos;
  DWORD fdwConversion;
  DWORD fdwSentence;
  union{
    LOGFONTA A;
    LOGFONTW W;
  } lfFont;
  COMPOSITIONFORM cfCompForm;
  CANDIDATEFORM cfCandForm[4];
  HIMCC hCompStr;
  HIMCC hCandInfo;
  HIMCC hGuideLine;
  HIMCC hPrivate;
  DWORD dwNumMsgBuf;
  HIMCC hMsgBuf;
  DWORD fdwInit;
  DWORD dwReserve[3]
} INPUTCONTEXT, *PINPUTCONTEXT, NEAR *NPINPUTCONTEXT, FAR *LPINPUTCONTEXT;

Members

  • hWnd
    Handle to the window that uses the input context.
  • fOpen
    Boolean that indicates the present status of the opened or closed IME.
  • hwndImeInUse
    Handle to the input method editor (IME) control window.
  • ptStatusWndPos
    Position of the status window.
  • ptSoftKbdPos
    Position of the input panel.
  • fdwConversion
    Conversion mode used by the IME composition engine.
  • fdwSentence
    Sentence mode used by the IME composition engine.
  • lfFont
    LOGFONT structure used by the IME user interface to draw the composition string.
  • cfCompForm
    COMPOSITIONFORM structure used by the IME user interface to create the composition window.
  • cfCandForm
    CANDIDATEFORM structures used by the IME user interface to create the candidate windows. This IMC supports 4 candidate forms.
  • hCompStr
    Handle to the COMPOSITIONSTRING 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
    Number of messages stored in the hMsgBuf member.

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

    [Message1] [wParam1] [lParam1] {[Message2] [wParam2] [lParam2]{...{...{...}}}}

    All values are DWORDs.

  • fdwInit
    Initialize flag. When IME initializes the members of the INPUTCONTEXT structure, IME must set the bits of the member indicated by this flag. The following table shows the possible values that can be combined for this flag.

    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
    Reserved; set to zero.
