wxRealPoint Class Reference

#include <wx/gdicmn.h>

Detailed Description

A wxRealPoint is a useful data structure for graphics operations.

It contains floating point x and y members. See wxPoint for an integer version.

Note that the coordinates stored inside a wxRealPoint object may be negative and that wxRealPoint functions do not perform any check against negative values.
