Detailed Description

Structure representing a single input point (touch or mouse).

The HifPoint structure represents an active input point from the HIF system, such as a touch or mouse event. It contains information about the event type, a unique handle, and the event data itself.

Note

The ev.xp and ev.yp members of the b8HifEvent structure are 16-bit signed fixed-point numbers with 4 fractional bits. To obtain the integer part of the coordinates, shift right by 4 bits (i.e., ev.xp >> 4 and ev.yp >> 4).
