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.

Miscellaneous operators

Note that these operators are documented as class members (to make them easier to find) but, as their prototype shows, they are implemented as global operators; note that this is transparent to the user but it helps to understand why the following functions are documented to take the wxPoint they operate on as an explicit argument.
