1 2001-09-04 Angus Leeming <a.leeming@ic.ac.uk>
3 * ControlButtons.[Ch]: add an is_closing_ variable and isClosing method.
4 When Applying it's useful to know whether the dialog is about to close

235 in the read-only list only when the read-only status of the document
237 (refresh): moved this stuff into refreshReadOnly.
239 2001-05-18 Angus Leeming <a.leeming@ic.ac.uk>
241 * ControlPrint.C (c-tor):
242 * ControlPreamble.C (c-tor): initialise params_ and thereby cure crash.

432 now inside namespace character.
434 * ControlCitation.[Ch]: moved out all the helper functions and the
435 enums into their own file. Simplified interface.
436 * biblio.[Ch]: new files; contain the citation helper functions,
437 now inside namespace biblio. Will be of use also to an improved
440 * ControlGraphics.[Ch]:

479 * ControlInset.h (apply): fix bug. Can now create new insets again.
481 * README: describe program flow.
483 2001-03-24 Lars Gullik Bjønnes <larsbj@trylle.birdstep.com>
485 * Makefile.am (libcontrollers_la_SOURCES): add ControlDialogs.h
487 2001-03-23 Angus Leeming <a.leeming@ic.ac.uk>
489 * ControlDialogs.h: moved class ControlInset into its own file.
491 * ControlInset.h: new file. class ControlInset has been expanded to take
492 two template parameters, Inset and Params. Believe that all inset
493 controllers can be derived from this with the minimum of effort.
495 * ControlBibitem.[Ch]:
496 * ControlBibtex.[Ch]:
497 * ControlCitation.[Ch]:
498 * ControlCommand.[Ch]: moved most code into ControlInset.
500 * lots of files. Moved protected stuff into private where possible.
503 * ControlInclude.[Ch]:
504 * ControlUrl.[Ch]: new files; controllers for the LaTeX error,
505 Include and Url popups, respectively.
508 * Makefile.am: associated changes.
510 2001-03-23 Angus Leeming <a.leeming@ic.ac.uk>
512 * ControlCredits.[Ch] (getCredits): returns a stringstream not a
515 2001-03-23 Jean-Marc Lasgouttes <Jean-Marc.Lasgouttes@inria.fr>
517 * ControlCredits.C (getCredits): remove std:: qualifier for
520 2001-03-23 Lars Gullik Bjønnes <larsbj@trylle.birdstep.com>
522 * ControlCredits.C (getCredits): add std:: on vector
524 2001-03-22 Lars Gullik Bjønnes <larsbj@trylle.birdstep.com>
526 * ControlCredits.C: remove using that is only used once, use
527 std::ios instead of std::iosbase, add some annoying comments.
529 2001-03-22 Angus Leeming <a.leeming@ic.ac.uk>
531 * lots of header files: improved explanatory notes.
533 * ControlBase.[Ch]: removed LyXView & lv_ and methods using it.
534 ControlBase is now a class that only controls the interaction of the
535 View with the ButtonController.
537 * ControlConnections.[Ch]: added LyXView & lv_ and associated methods
538 to ControlConnectBase. The class controls the connection/disconnection
539 of signals from the LyX kernel and makes available the kernel (through
540 lv_) to daughter controller classes.
541 Moved out class ControlConnectInset to a new file ControlDialogs.h.
543 * ControlDialogs.h: new file. Contains the definition of two template
544 controller classes, ControlDialog and ControlInset (was
545 ControlConnectInset). ControlInset is a parent class for controllers
546 of inset-popups. ControlDialogs is the rather uninspired name for
547 the base class of all non-inset popups. (Eg, Document and Paragraph.)
548 ControlDialogs is reaching a state of maturity as several popups now use
549 it and its functionality becomes clear. ControlInset is still in a state
550 of flux. It is likely that functionality will be moved out of
551 ControlCommands and into it.
553 * GUI.h: new file. Moved all the template GUIXXX classes out of the
554 individual Controller header files and into one place. These classes
555 serve only as convenient wrappers to simplify code in the respective
556 frontends' Dialogs::c-tor. Now all derived from a templatised parent.
558 * ControlCharacter.[Ch] (show, update, hide):
559 * ControlLog.[Ch] (show, update, hide):
560 * ControlVCLog.[Ch] (show, update, hide): moved back into
561 the ControlDialogs base class.
562 (setParams, clearParams): new methods containing controller-specific
563 code to set/reset the parameters manipulated by the view.
565 * ControlCommand.[Ch] (clearParams): a new virtual method, by default
567 (hide): calls clearParams.
569 * ControlCitation.[Ch] (hide): renamed as clearParams, a method called
570 by ControlCommand::hide().
572 * ControlCopyright.[Ch]:
573 * ControlCredits.[Ch]: new files; controllers for the copyright and
574 credits popups, respectively.
576 2001-03-21 Lars Gullik Bjønnes <larsbj@trylle.birdstep.com>
578 * ControlCharacter.C: fix typo
580 2001-03-21 Angus Leeming <a.leeming@ic.ac.uk>
582 * ControlCharacter.[Ch]: new files; controller for the character popup.
584 * ControlCitation.[Ch] (getStringFromVector, getVectorFromString):
585 moved to new files helper_funcs.[Ch].
587 * helper_funcs.[Ch]: new files. Some useful helper functions and
590 * Makefile.am: added new files.
592 2001-03-20 Angus Leeming <a.leeming@ic.ac.uk>
594 * ControlCitation.C (getBibkeyInfo): parse non-BibTeX entries correctly.
596 2001-03-20 Angus Leeming <a.leeming@ic.ac.uk>
599 * ControlVCLog.[Ch]: new files; controllers for LaTeX and Version
600 Control log files, respectively.
602 * Makefile.am: added new files.
604 2001-03-19 Angus Leeming <a.leeming@ic.ac.uk>
606 * ControlBibtex.[Ch]: new files; controller for an InsetBibtex popup.
608 * Makefile.am: added ControlBibtex.[Ch].
610 2001-03-16 Angus Leeming <a.leeming@ic.ac.uk>
613 * ControlCitation.C: added "using SigC::slot" declaration.
615 * ControlCitation.C (getStringFromVector): re-apply Dekel's recent fix
616 to FormCitation.C prior to the merger: "Do not put space between
619 2001-03-15 Lars Gullik Bjønnes <larsbj@trylle.birdstep.com>
621 * several files: remove CXX_WORKING_NAMESPACES
623 * ButtonController.h: noncopyable is in namespace boost
624 * ButtonPolicies.h: ditto
626 2001-03-14 Angus Leeming <a.leeming@ic.ac.uk>
628 * Merging changes from BRANCH_MVC back into HEAD.
630 2001-03-12 Angus Leeming <a.leeming@ic.ac.uk>
632 * Makefile.am: add ControlBibitem.[Ch].
634 * ControlBibitem.[Ch]: new files that together define the Controller
637 * ControlCommand.h (c-tor): give kb_action a default value of
640 * ControlCommand.C (apply): do nothing if kb_action is LFUN_NOACTION.
642 * ControlCitation.[Ch]: moved search functions out of class.
643 (bibkeysInfo): new method. Returns const reference to private data.
644 (searchKeys): added case-sensitive switch. Used only by simpleSearch
647 2001-03-09 Angus Leeming <a.leeming@ic.ac.uk>
649 * ControlCitation.[Ch]: added Search functions to the class,
650 (shamelessly lifted from Marco's gnome code). I think that these would
651 be better as helper functions outside the class, but this is a first
654 2001-03-07 Angus Leeming <a.leeming@ic.ac.uk>
656 * ControlCitation.[Ch]: (getBibkeyList): removed from class
658 (getBibkeys, getBibkeyInfo): added to class ControlCitation.
659 (getStringFromVector, getVectorFromString, parseBibTeX): new helper
660 funcs. parseBibTeX() is lifted staraight out of Marco's gnome
661 implementation of FormCitation.
663 2001-03-05 Angus Leeming <a.leeming@ic.ac.uk>
665 * ButtonPolicies.h: add SMI_NOOP to enum.
667 * ButtonPolicies.C (nextState): add if-statement for SMI_NOOP.
669 * ButtonController.C (input): add "optimising" if-statement. Actually,
670 things don't work correctly without it...
672 2001-03-02 John Levon <moz@compsoc.man.ac.uk>
674 * ViewBase.h: remove #pragma directive
676 * ControlConnection.[Ch] (ControlConnectBI c-tor): add explicit c-tor
679 2001-03-02 Angus Leeming <a.leeming@ic.ac.uk>
681 * ButtonPolicies.[Ch]: moved from ../ButtonPolicies.[Ch]
683 * Makefile.am: added ButtonPolicies.[Ch]
685 * ButtonController.[Ch]: ButtonController is split into
686 ButtonControllerBase and a template ButtonController class. The base
687 class no longer stores a pointer to a ButtonPolicy, but instead
688 accesses the actual instantiation of the policy through a pure virtual
689 method bp(). This method and the ButtonPolicy itself are instantiated
690 in the templatised ButtonController class. This class is derived from
691 the GUI-specific GUIBC class, meaning that the frontends know
692 nothing about the actual policy decided upon by the controllers.
694 * ControlBase.[Ch]: No longer store the View or the ButtonController.
695 Instead the actual instantiations are accessed through pure virtual
696 methods view() and bc(). The daughter classes are responsible for the
697 actual View and ButtonController.
699 * ControlCitation.h: the templatised class GUICitation instantiates
700 the methods view() and bc(). It also stores the instances of the
701 View and ButtonController.
703 2001-02-23 Angus Leeming <a.leeming@ic.ac.uk>
705 * ButtonControllerBase.[Ch]: renamed as ButtonController.[Ch]. Class
706 also changed to ButtonController.
709 * ControlConnections.[Ch]:
710 * ControlCommand.[Ch]:
711 * ControlCitation.[Ch]:
712 * ViewBase.h: Changes associated with this.
714 2001-01-15 Angus Leeming <a.leeming@ic.ac.uk>
716 * ButtonControllerBase.[Ch]: new files. Split Allan's original
717 xforms/ButtonController class into a GUI-I class (here) and an
718 xforms-specific derived class, to be found in xforms/xformsBC.[Ch].
720 * ControlBase.[Ch]: new files. ControlBase is an abstract base class
721 from which all Dialog Controllers should be derived. the Controllers
722 are GUI-independent, but are designed to control the behaviour of
723 GUI-specific implementaions of each dialog.
725 * ControlConnections.[Ch]: new files. Classes controlling the
726 connections of buffer-independent, buffer-dependent and Inset dialogs
729 * ControlCommand.[Ch]: new files. A controller for all dialogs for the
730 InsetCommand subset of insets.
732 * ControlCitation.[Ch]: new files. The test specialisation! A
733 controller for the Citation dialog.
735 * ViewBase.h: new file. ViewBase is an abstract base class from which
736 GUI-specific dialogs should be derived. The functionality that the GUIs
737 must now implement is much reduced.
