2 * figinset.C - part of LyX project
5 /* Rework of path-handling (Matthias 04.07.1996 )
6 * ------------------------------------------------
7 * figinsets keep an absolute path to the eps-file.
8 * For the user alway a relative path appears
9 * (in lyx-file, latex-file and edit-popup).
10 * To calculate this relative path the path to the
11 * document where the figinset is in is needed.
12 * This is done by a reference to the buffer, called
13 * figinset::cbuffer. To be up to date the cbuffer
14 * is sometimes set to the current buffer
15 * bufferlist.current(), when it can be assumed that
16 * this operation happens in the current buffer.
17 * This is true for InsetFig::Edit(...),
18 * InsetFig::InsetFig(...), InsetFig::Read(...),
19 * InsetFig::Write and InsetFig::Latex(...).
20 * Therefore the bufferlist has to make sure that
21 * during these operations bufferlist.current()
22 * returns the buffer where the figinsets are in.
23 * This made few changes in buffer.C necessary.
25 * The above is not totally valid anymore. (Lgb)
