CANDIDATELIST

The CANDIDATELIST structure contains information about a candidate list.

typedef struct tagCANDIDATELIST {
  DWORD  dwSize;       
  DWORD  dwStyle;      
  DWORD  dwCount;      
  DWORD  dwSelection;  
  DWORD  dwPageStart;  
  DWORD  dwPageSize;   
  DWORD  dwOffset[1];  
} CANDIDATELIST, *PCANDIDATELIST;

Members

dwSize

Size, in bytes, of the structure, the offset array, and all candidate strings.

dwStyle

Candidate style values. This member can be one or more of the following values.

Value	Meaning
IME_CAND_UNKNOWN	Candidates are in a style other than listed here.
IME_CAND_READ	Candidates are in same reading.
IME_CAND_CODE	Candidates are in a code range.
IME_CAND_MEANING	Candidates are in same meaning.
IME_CAND_RADICAL	Candidates use same radical character.
IME_CAND_STROKES	Candidates are in same number of strokes.

For the IME_CAND_CODE style, the candidate list has a special structure depending on the value of the dwCount member. If dwCount is 1, the dwOffset member contains a single DBCS character rather than an offset, and no candidate string is provided. If the dwCount member is greater than 1, the dwOffset member contains valid offsets, and the candidate strings are text representations of individual DBCS character values in hexadecimal notation.

dwCount

Number of candidate strings.

dwSelection

Index of the selected candidate string.

dwPageStart

Index of the first candidate string in the candidate window. This varies as the user presses the PAGE UP and PAGE DOWN keys.

dwPageSize

Number of candidate strings to be shown in one page in the candidate window. The user can move to the next page by pressing IME-defined keys, such as the PAGE UP or PAGE DOWN key. If this number is zero, an application can define a proper value by itself.

dwOffset

Offset to the start of the first candidate string, relative to the start of this structure. The offsets for subsequent strings immediately follow this member, forming an array of 32-bit offsets.

Remarks

The candidate strings immediately follow the last offset in the dwOffset array.

Requirements

  Windows NT/2000: Requires Windows NT 4.0 or later.
  Windows 95/98: Requires Windows 95 or later.
  Header: Declared in Imm.h.
