Inkscape::Text::Layout::iterator Class Reference

#include <Layout-TNG.h>

List of all members.

Detailed Description

Holds a position within the glyph output of Layout.

Used to access the output of a Layout, query information and generally move around in it. See Layout for a glossary of the names of functions.

I'm not going to document all the methods because most of their names make their function self-evident.

A lot of the functions would do the same thing in a naive implementation for latin-only text, for example nextCharacter(), nextCursorPosition() and cursorRight(). Generally it's fairly obvious which one you should use in a given situation, but sometimes you might need to put some thought in to it.

All the methods return false if the requested action would have caused the current position to move out of bounds. In this case the position is moved to either begin() or end(), depending on which direction you were going.

Note that some characters do not have a glyph representation (eg line breaks), so if you try using prev/nextGlyph() from one of these you're heading for a crash.
