This commit creates a error_lists map member inside the Buffer class. I had no choice but to use string for the map key. This is because the only information that could be passed to the controller is a string. With this new architecture, persistent error lists are now possible. * Buffer - errorList_, addError(), : deleted - std::map<std::string, ErrorList> errorLists_ : new member - errorList(std::string const & type): associated accessors * buffer_funcs.C - bufferErrors(Buffer const & buf, TeXErrors const & terr): now needs a third errorList argument - bufferErrors(Buffer const & buf, ErrorList const & el): deleted. * Converter - convert(): now needs an ErrorList argument instead of filling the Buffer errorList member directly. - runLaTeX(): ditto - scanLog(): ditto * CutAndPaste.C - pasteParagraphList(): ditto - pasteSelection(): ditto * lyxtext.h/text.C - readParagraph(): ditto - LyXText::read(): ditto * importer: - Importer::Import(): ditto * BufferView_pimpl.C - loadLyXFile(): send the Buffer::errors() signal instead of calling LyXView::showErrorList() directly. * exporter.C - Export(): send the Buffer::errors() signal instead of calling LyXView::showErrorList() directly in lyxfunc.C * ControlErrorList.C - initialiseParams(): translation operation transfered here from LyXView::showErrorList(). * LyXView.C - LoadLyXFile(): add a showErrorList("Parse") call. - showErrorList(): simplified due to code transferred to the ControlErrorList. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@14652 a592a061-630c-0410-9148-cb99ea01b6c8
