2005-02-08 Lars Gullik Bjonnes <larsbj@gullik.net>
* text3.C (cursorPrevious): return true if depm changed something
(cursorNext): ditto
(dispatch): rename sl to oldTopSlice, remove moving use the new
NoUpdate func attrib instead. Make sure that needsUpdate is set
for function that have NoUpdate, but where depm might have changed
the buffer anyway.
* text2.C (cursorLeft): make us return true if depm changed
something
(cursorRight): ditto
(cursorUpParagraph): ditto
(curosrDownParagraph): ditto
(cursorUp, cursorDown): ditto, make sure to read comments in code
(deleteEmptyParagraphMechanism): remove an assert, also return
true if just a single char was deleted.
* text.C (cursorRightOneWord, cursorLeftOneWord): use a temp
cursor that we modify, to avoid modifying an active cursor before
we call setCursor. This allows depm to run. Also return true if
depm deleted something.
* lyxtext.h: Make cursorUp, cursorDown, cursorLeft, cursorRight,
cursorLeftOneWord, cursorRightOneWord, cursorUpParagraph,
cursorDownParagraph, cursorPrevious and cursorNext, return true if
something was changed in the buffer because of them (ie. depm run)
* lyxfunc.C (processKeySym): add BOOST_CURRENT_FUNCTION to some
debug messages. Make update by default be false. Make sure that
the result of update is retained throught several calls down to
dispatch.
* LyXAction.h: add a new func_attrib: NoUpdate
* LyXAction.C (init): add noupdate to LFUN_LEFT, LFUN_RIGHT,
LFUN_DOWN, LFUN_HOME, LFUN_END, LFUN_DOWN_PARAGRAPH,
LFUN_UP_PARAGRAPH, LFUN_NEXT, LFUN_PRIOR, LFUN_UP, LFUN_WORDRIGHT
and LFUN_WORDLEFT
(init): add missing lfuns: LFUN_FINISHED_*, LFUN_MOUSE_*
2005-02-07 Jean-Marc Lasgouttes <lasgouttes@lyx.org>
* BufferView_pimpl.C: replace all occurences of bv_->cursor(),
