} TC_HITTESTINFO;
Members
pt
Position to hit test, in client coordinates.
flags
Variable that receives the results of a hit test. The tab control sets this member to one of the following values:
| Value | Meaning |
| TCHT_NOWHERE | The position is not over a tab. |
| TCHT_ONITEM | The position is over a tab, but not over its icon or its text. For owner-drawn tab controls, this value is specified if the position is anywhere over a tab. |
| TCHT_ONITEMICON | The position is over a tab's icon. |
| TCHT_ONITEMLABEL | The position is over a tab's text. |
TCHT_ONITEM is a bitwise OR operation on TCHT_ONITEMICON and TCHT_ONITEMLABEL.
Remarks
This structure is used with the TCM_HITTEST message.
