Rewrite the label numbering code. * buffer_funcs.cpp (updateLabels): new function taking a buffer and a ParIterator as arguments. This one is used to update labels into an InsetText. Cleanup the code to reset depth. Call setLabel for each paragraph, and then updateLabel on each inset it contains. (setCaptionLabels, setCaptions): removed. (setLabel): use Counters::current_float to make caption paragraphs labels. * insets/Inset.h (updateLabels): new virtual method, empty by default; this numbers the inset itself (if relevant) and then all the paragraphs it may contain. * insets/InsetText.cpp (updateLabels): basically calls lyx::updateLabels from buffer_func.cpp. * insets/InsetCaption.cpp (addToToc): use the label constructed by updateLabels. (computeFullLabel): removed. (metrics, plaintext): don't use computeFullLabel. (updateLabels): new method; set the label from Counters::current_float. * insets/InsetWrap.cpp (updateLabels): * insets/InsetFloat.cpp (updateLabel): new method; sets Counters::current_float to the float type. * insets/InsetBranch.cpp (updateLabels): new method; the numbering is reset afterwards if the branch is inactive. (bug 2671) * insets/InsetNote.cpp (updateLabels): new method; the numbering is reset after the underlying InsetText has been numbered. (bug 2671) * insets/InsetTabular.cpp (updateLabels): new method (also handles longtable) * insets/InsetListings.cpp (updateLabels): new method; mimics what is done for Floats (although Listings are not floats technically) * insets/InsetInclude.cpp (getScreenLabel): in the listings case, use the computed label. (updateLabels): new method; that either renumbers the child document or number the current listing. * LyXFunc.cpp (menuNew): do not updateLabels on empty documents (why do we do that at all?) git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@19482 a592a061-630c-0410-9148-cb99ea01b6c8
