TCITEMA structure (commctrl.h)
Specifies or receives the attributes of a tab item. It is used with the TCM_INSERTITEM, TCM_GETITEM, and TCM_SETITEM messages. This structure supersedes the TC_ITEM structure.
Syntax
typedef struct tagTCITEMA {
UINT mask;
DWORD dwState;
DWORD dwStateMask;
LPSTR pszText;
int cchTextMax;
int iImage;
LPARAM lParam;
} TCITEMA, *LPTCITEMA;
Members
mask
Type: UINT
Value that specifies which members to retrieve or set. This member can be a combination of the following values:
Value | Meaning |
---|---|
|
The iImage member is valid. |
|
The lParam member is valid. |
|
The string pointed to by pszText will be displayed in the direction opposite to the text in the parent window. |
|
Version 4.70. The dwState member is valid. |
|
The pszText member is valid. |
dwState
Type: DWORD
Version 4.70. Specifies the item's current state if information is being retrieved. If item information is being set, this member contains the state value to be set for the item. For a list of valid tab control item states, see Tab Control Item States. This member is ignored in the TCM_INSERTITEM message.
dwStateMask
Type: DWORD
Version 4.70. Specifies which bits of the dwState member contain valid information. This member is ignored in the TCM_INSERTITEM message.
pszText
Type: LPTSTR
Pointer to a null-terminated string that contains the tab text when item information is being set. If item information is being retrieved, this member specifies the address of the buffer that receives the tab text.
cchTextMax
Type: int
Size in TCHARs of the buffer pointed to by the pszText member. If the structure is not receiving information, this member is ignored.
iImage
Type: int
Index in the tab control's image list, or -1 if there is no image for the tab.
lParam
Type: LPARAM
Application-defined data associated with the tab control item. If more or less than 4 bytes of application-defined data exist per tab, an application must define a structure and use it instead of the TCITEM structure. The first member of the application-defined structure must be a TCITEMHEADER structure.
Remarks
Typically, windows display text left-to-right (LTR). Windows can be mirrored to display languages such as Hebrew or Arabic that read right-to-left (RTL). Ordinarily, pszText will be displayed in the same direction as the text in its parent window. If TCIF_RTLREADING is set, pszText will read in the opposite direction from the text in the parent window.
Note
The commctrl.h header defines TCITEM as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
