The TPoint Class

Header File

Description

TPoint is a support class, derived from tagPOINT. The tagPOINT struct is defined as

struct tagPOINT {
   int x;
   int y;
};

TPoint encapsulates the notion of a two-dimensional point that usually represents a screen position. TPoint inherits two data members, the coordinates x and y, from tagPOINT. Member functions and operators are provided for comparing, assigning, and manipulating points. Overloaded << and >> operators allow chained insertion and extraction of TPoint objects with streams.
