The TTHITTESTINFO structure contains information that a tooltip control uses to determine whether a point is in the bounding rectangle of the specified tool. If the point is in the rectangle, the structure receives information about the tool.
typedef struct _TT_HITTESTINFO { // tthti
HWND hwnd;
POINT pt;
TOOLINFO ti;
} TTHITTESTINFO, FAR * LPHITTESTINFO;
Members
