// This file is meant to contain utility classes for users of the wxWidgets library.
// All classes in this file are dependent on wxBase and wxCore libraries! Meaning
// you will have to use wxCore header files and link against wxCore (GUI) to build
// them. For tools which require only wxBase, see wxBaseTools.h

// pxTextWrapperBase
// --------------------------------------------------------------------------------------
// this class is used to wrap the text on word boundary: wrapping is done by calling
// OnStartLine() and OnOutputLine() functions. This class by itself can be used as a
// line counting tool, but produces no formatted text output.
//
// [class "borrowed" from wxWidgets private code, made public, and renamed to avoid possible
// conflicts with future editions of wxWidgets which might make it public. Why this isn't
// publicly available already in wxBase I'll never know-- air]
