The DISPCELLTAGINFO structure provides information about the cell or sub-cell tag.
| Member | Description | |
| uStructSize | Size of this structure in bytes, for versioning. Use the sizeof() macro to calculate this value. | |
| uMask | Value that indicates which members contains valid data for setting, or which members should be updated. Flags can be combined using the bitwise 'OR. Possible values are: | |
| Value | Meaning | |
| DCTF_ALL | [0x0000000F] All members must be valid or must be filled in. | |
| DCTF_POSITION | [0x00000001] the uPosition member must be valid or must be filled in. | |
| DCTF_ALIGN | [0x00000002] the uAlign member must be valid or must be filled in. | |
| DCTF_TYPE | [0x00000004] the szText member must be valid or must be filled in. | |
| DCTF_TEXT | [0x00000008] the uTagType member must be valid or must be filled in. | |
| uPosition | The number of rows to count before placing the tag. | |
| uAlign | Value that specifies the origin point from which to count the rows specified in the uRow parameter. For example, if uAlign is DISPWIN_ALIGN_BOTTOMLEFT and uRow is 4, the application will count 4 rows from the bottom and place the tag on that location. Possible values are: | |
| Value | Meaning | |
| DISPWIN_ALIGN_TOPLEFT | [0x0000] Start counting rows from the top of the cell. The tag will be left justified. | |
| DISPWIN_ALIGN_LEFTCENTER | [0x0001] The tag is placed in the center, based on the height of the cell, and is left justified. | |
| DISPWIN_ALIGN_BOTTOMLEFT | [0x0002] Start counting rows from the bottom of the cell. The tag will be left justified. | |
| DISPWIN_ALIGN_TOPCENTER | [0x0003] The tag is placed in the center, based on the width of the cell, and is top justified. | |
| DISPWIN_ALIGN_BOTTOMCENTER | [0x0004] The tag is placed in the center, based on the width of the cell, and is bottom justified. | |
| DISPWIN_ALIGN_TOPRIGHT | [0x0005] Start counting rows from the top of the cell. The tag will be right justified. | |
| DISPWIN_ALIGN_RIGHTCENTER | [0x0006] The tag is placed in the center, based on the height of the cell, and is right justified. | |
| DISPWIN_ALIGN_BOTTOMRIGHT | [0x0007] Start counting rows from the bottom of the cell. The tag will be right justified. | |
| szText | String containing a custom tag. This parameter is only used if uTagType is set to DISPWIN_TYPE_USERDATA. | |
| uTagType | Value that represents the type of tag to be added. Possible values are: | |
| Value | Meaning | |
| DISPWIN_TYPE_USERDATA | [0x0000] User data tag | |
| DISPWIN_TYPE_SCALE | [0x0001] Scale tag | |
| DISPWIN_TYPE_WLCENTERWIDTH | [0x0002] Window level tag | |
| DISPWIN_TYPE_FIELDOFVIEW | [0x0003] Field of view tag | |
| DISPWIN_TYPE_OWNERDRAW | [0x0004] Owner draw tag | |
| DISPWIN_TYPE_FRAME | [0x0005] Frame tag. | |
| DISPWIN_TYPE_RULERUNIT | [0x0005] Ruler unit tag. | |
