IPoint

The IPoint class represent points in two-dimensional space. In addition to all the functions inherited from its base class, IPair, the IPoint class provides additional functions.

OS/2 Considerations

You can also construct objects of this class from a Presentation Manager Toolkit POINTL structure.

IPoint - Member Functions and Data by Group

You can create, copy, and assign objects of this class. This class uses the compiler-generated copy constructor and assignment operator to copy and assign IPoint objects.
