**********************************************************************

BUGS:
-----

GENERAL

* Check FIXME, TODO, and #warning in the LyX code

* Resolve compiler warnings

* Watch for bugzilla.lyx.org entries


FILE

* LyX tries to delete /tmp if it is called with invalid arguments

* Loading de_Userguide.lyx results in two parse errors:
  Paragraph ended in line 21206
  Missing \end_layout.
  Paragraph ended in line 21301
  Missing \end_layout.
  I don't know if that is a lyx2lyx or LyX problem. LyX 1.4 can read the file.

* Non-ascii filenames do not work at all and result in an assertion or garbage.

* open lyx, create a new document, enter a few chars, quit, click cancel, lyx
  still quits.

* Change Tools->Preferences->User interface->User interface to something like
  "kornel.default.ui"; save prefs; exit LyX; restart LyX; => crash; 
  in the preferences file, there is an entry \bind_file "/Something/kornel.default"

  In QPrefsDialog.C:1736, function PrefUserInterface::select_ui() calls
        form_->controller().browseUI(qstring_to_ucs4(uiFileED->text())))
  which in turn calls
        ControlPrefs.C:118
        browseLibFile(lyx::from_ascii("ui"), file, lyx::from_ascii("ui"),
                _("Choose UI file"), FileFilterList(_("LyX UI files (*.ui)")));
  In this function, the extension is removed, because it is the default ("ui" in 
  this case). This behaviour applies to
    ControlPrefs::browsebind,  ControlPrefs::browseUI
    ControlPrefs::browsekbmap, ControlPrefs::browsedict
  Setting the default extension here to something invalid, is a hack, but works.
  (Invalid may be e.g. "*")


SPELL CHECKING (Joost 4/11/06)

* Words with umlauts or accents do not arrive as a whole word in the spell
  checker.
  PARTIALLY FIXED (Georg 2006-12-10): pspell should work (untested), ispell
  works if lyxrc.isp_use_input_encoding == true, aspell works on linux,
  cygwin and native windows (it is not clear yet whether it works on OS X).
  ispell (if lyxrc.isp_use_input_encoding == false) does not work yet.

* The cursor does not go to the currently checked word (or maybe it goes,
  but the screen is not updated so that one does not see the word).
  
* When replacing a misspelled word during spell checking, the screen is not 
  updated immediately.


TABLE OF CONTENTS

* In TOC, the buttons "Up", "Down", "Promote", and "Demote" are not
  self-explaining. Why don't we group them in two pairs: Section Up/Down, Level
  Up/Down? The arrangement of the buttons may also give some hint to the user.

* The items in the treeview are editable


DIALOGS

* when opening an already opened document (or a document with newer backup),
  the mouse pointer turns into a clock, although it waits for confirmation

* If you try to view a document as postscript that cannot be typeset because
  of LaTeX errors and export to LaTeX afterwards you will get the old error
  list again, although the export succeded.


MATH CONTROL PANEL

* In the math control panel, there is no icon for the "Fractions" button.

* In the math control panel, the buttons are too small.
  The reason is probably that qt resizes the icons so that they fit into the
  button, leaving some margin. This leads to different scales for each icon.
  qt3 did not resize the icons. Can this be set in qt4, too? MG: Why don't we 
  enlarge the buttons?


OTHER PANELS

* The visual table size selection on the the "Insert Table" dialog has gone
  (Joost 3/11/06).

* The UI for bullet selection in the documents settings looks weird
  (Joost 4/11/06):
  There is a big listbox just to select one of the four levels.
  Isn't this supposed to be a drop-down list or something like that?

* The bullet selection widget shows the bullets in 5 columns (instead of 6)
  for me, and hence does not fit into the window.
  (JSpitzm 2006-11-06)

* The style name in the BibTeX Bibliography panel (near the Browse... button)
  disappears after closing and reopening the panel.
  (Enrico 2006-12-01)


MULTIPLE WINDOWS / DOCUMENTS

* There are cursor problems when the same document is opened in two windows
  (Joost 4/11/06).

  Information from Abdel:
  Yes, this is the famous dEPM bug (delete Empty Paragraph Mechanism).
  There are two ways to fix that:
  1) the correct way: fix the dEPM to not invalidate the cursor.
  2) the easy way: disable the cursor on focus out event and re-enable it at
  focus in event and jump the saved position (at focus out).


TOOLBARS & MINIBUFFER

* When toolbars are hidden, they pop up again after clicking on the document
  area (Joost 4/11/06).
  Comment by Bo: Can not reproduce, details please.


TOOLTIPS:

* Tooltips are no longer shown


MENUS

* Some oddities with View menu on MAC (Bennett 3/11/06): DVI does not appear
  in the menu, even though a converter and viewer are defined in Preferences.
  It turned out that this was a user error: a configuration file of 1.4 was
  used without the document flag.
  This should definitely be documented somewhere before the final release,
  because many users will copy their old config files.

* Mysterious *.po entry:

  #: src/frontends/qt4/ui/QViewSourceUi.ui:31
  msgid ""
  "<html><head><meta name=\"qrichtext\" content=\"1\" /></head><body style=\" "
  "white-space: pre-wrap; font-family:Sans Serif; font-size:13pt; font-"
  "weight:400; font-style:normal; text-decoration:none;\"><p style=\"-qt-"
  "paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; "
  "margin-right:0px; -qt-block-indent:0; text-indent:0px;\"></p></body></html>"
  msgstr ""


EDITING

* Create a new document; enter a few chars; press return; from the 
  environments combo box on the top left corner select anything, e.g., 'Part'; 
  try to enter text => you can't! 
  MG: This must be a GUI problem; when using keyboard shortcuts (Alt-P-...),
  the problem does not occur; it does not matter whether the cursor is in the last line
  JSpitzm: The problem is that the workarea doesn't get focus after the combo selection.

* Open "de_Intro.lyx"; mark first word ("Einführung"); invoke "ert-insert" => seg fault

* edit->text style->capitalize/lower/upper case doesn't work due to change
  tracking-related changes.

* insert->note->lyx note, enter a few chars, collapse the note. Copy the note
  several times (three lines?), use mouse to select. Lyx crashes with

  Assertion triggered in void lyx::LyXText::dispatch(lyx::LCursor&, lyx::FuncRequest&) by failing check "cur.text() == this" in file src/text3.C:323

  NOTE: this is unrelated to the button face-lift patch.


CHANGE TRACKING

* No change bar is given in LaTeX output if (only) the par break has changed

* In tables, cut & paste (complete cells) do not support change tracking

* When accepting or rejecting changes, paragraphs with deleted par breaks are
  not merged (in top-level pars & in nested text insets)

* When running "find & replace", the cursor is not moved forward, such 
  that LyX always offers to replace the same string

* LyX crashes if you want to accept/reject an end-of-par character only


LAYOUT

* environments when using czech translation doesnt work: e.g.
  itemize("Polozka") -> ERROR (layoutSelected): layout not found! (P. Sanda)


PAINTING & PERFORMANCE

* Open de_UserGuide.lyx; go to the end of the document; click into the footnote (with the mouse -
  this is important for the test case); add a character into the note 
  => the complete footnote is expanded but only the current line is repainted

* In the splash screen, the LyX version number is printed with a very, very
  small font size such that it becomes almost invisible on Windows.

* END_LABEL_* handling in RowPainer::paintLast() is broken. In regular text,
  label boxes are not completely visible (because we shrinked the margin on 
  screen?). Inside of insets, they don't work at all. 

* Too much painting 2 (Edwin 3/11/2006): There is also a lot of painting going
  on when selecting text. When selecting a word the whole screen is repainted.
  PARTLY FIXED (Abdel 2006-11-20): there's a full repaint only when the mouse is
  released. More to come in this area.

* Too much painting 1 (Edwin 3/11/2006): when i click in the workarea (to put
  the cursor in another part of the text) the screen is repainted *twice*
  whereas it seems to me that no repainting is necessary at all.
  PARTLY FIXED (Abdel 2006-11-20): except for math insets.

* Too much painting 3 (Edwin 3/11/2006): the screen is repainted even when the
  selection does not change (moving the mouse with the left button pushed down 
  always triggers a repaint).
  PARTLY FIXED (Abdel 2006-11-20): When within the main text inset only the
  current line is repainted.

* The cursor is not L-shaped for foreign languages

* Slowness on MAC 1 (Bennett 3/11/06):
  There seems to be a fraction of a second lag between when I press a key and
  when the letter appears on screen -- but the time lag doesn't obviously vary
  with the amount of text on the screen (as was the case previously). Right now,
  the speed of normal text entry makes LyX-1.5 usable on my
  not-fast-but-still-not-outdated computer. (Not sure how it would be on my
  slow-but-still-usable laptop.)

* Slowness on MAC 2 (Bennett 3/11/06):
  Speed is still an issue typing in insets: noticeable lag between typing and
  text appearing on screen. This does not seem to be compounded by having nested
  insets, and it seems to be compounded only a little by the amount of text in
  the inset. (This is especially a problem in math environments.)
  PARTLY FIXED (Abdel 2006-11-20): except for math insets.

* Slowness on MAC 3 (Bennett 3/11/06): Some operations that with 1.4 are
  pretty much instantaneous (inserting a footnote, dragging the mouse, switching
  to LyX from another application, opening dialogs, etc.) take quite a long time
  to complete in 1.5.

* Some math symbols are not displayed (from Enrico Forestieri)
  I noticed that some math symbols are not shown on screen. This seems
  to be platform dependent. The following is a table illustrating the
  situation on three different platforms. Here "no" means that the
  symbol is not shown on screen (the symbol is invisible but occupies
  space: it is as a sort of \phantom), and "yes" that it is shown.
  ---------------------------------------
  Symbol         Linux   Solaris   Cygwin
  ---------------------------------------
  \Omega          no       no        no
  \int            yes      yes       no
  \oint           yes      yes       no
  \otimes         no       no        no
  \nleqslant      no       no        no
  \spadesuit(*)   yes      no        yes
  ---------------------------------------
  (*) On solaris, a square is shown on screen instead of nothing.
 - Further comments from Georg: This is probably a qt4 font drawing problem,
   since \Omega works fine in 1.4.3, and my debugging results showed that the
   correct font is found and used (cmr10).
 - Solved problem with \int and \oint on Windows (Enrico 2006-12-06).



MAC OS X

* Many issues with toolbars on MAC (Bennett 3/11/06):
  Most obvious of which are that icons are spaced too widely and that changes in
  the visibility of the toolbars with the GUI do not stick after the screen is
  redrawn).

* Many issue with dialogs on MAC (Bennett 3/11/06):
  Most obviously: the Preferences dialog -- which can only be accessed now via
  keyboard command, not from the menu -- appears initially too small and must be
  resized; not possible to select buttons with the keyboard).

  The prefs dialog size should be better now. See below (JSpitzm-2006-11-07).

* Menu bar disappears on MAC (instead of being disabled) when dialogs appear.


WONT FIX (for 1.5.0)

* There should be a close button on the tabs (Joost 3/11/06).
  There is now a Qt feature request:
  http://www.trolltech.com/developer/task-tracker/index_html?id=137891&method=entry

* TODO toolbar popup menu, currently disabled (Peter 9/11/06)  

* When content (sections/captions) is changed, the toc/lof/lot is not properly 
  updated.
  Abdel 2006-11-17: This one is not as simple as it seems as it involves a
  TocBackend update at each keystroke. Unless we manage to update a specific
  TocItem, this will be a WONTFIX for 1.5.0.


**********************************************************************

CREDITS:
--------

* Performance on Windows is bad. On my system, scrolling the User Guide takes
  10 seconds with LyX 1.4 and more than 30 seconds with LyX 1.5. 

  FIXED (Abdel 04/11/06): This was due to spurious message in QLPainter.C,

* When I have the same document in two windows, only the last selected paragraph
  in one of the windows gets updated.

  FIXED (Abdel 04/11/06): This was due my singlePar optimization. With my last
  commit, the optimization is enabled only if the WorkArea has the focus.

* No icon for "note-next" in the "review" toolbar.

  ADDED (JSpitzm 2006-11-04).

* Branches gui broken (buttons do nothing).

  FIXED (JSpitzm 2006-11-04).

* The title bar does not contain the document name when a new window is opened
  (Joost 4/11/06).

  FIXED (Abdel 05/11/06): This was due to "last_title" being a static variable
  in LyXView::updateWindowTitle() and also due to a potential bug in Qt:
  an update command to the window title seems to be ignored up until the window
  is shown.

* src/frontends/qt4/ui/QCitationUi.ui:70 "&Selected citations:" should be
  "&Selected Citations:".

  FIXED (MGerz 2006-11-05)

* In the "Math Delimiters" dialog, there is no need to repeat the term "Size"
  for all values in the selection box; the label is already named "Size"

  FIXED (MGerz 2006-11-05)

* If you open Document>Settings... or Tools>Preferences... for the first time,
  the dialog is much too small to show its content; if you invoke it the second
  time, everything is fine.

  This happens with qt 4.2.1 only, it does not happen with 4.1.4/4.1.5!

  FIXED (JSpitzm-2006-11-06): force updateGeometry() after the panelstack has 
  been created (with Qt >= 4.2 only). A brute method, but it works.

* If you open Edit>Test Style... for the first time, the choice text for
  "Never Toggled>Size" doesn't fit in the selection box (note that in German,
  texts are a bit longer than in English). Interestingly, if you invoke the
  dialog a second time, its button sizes are adjusted to their content.

  WONTFIX: This happens with qt >= 4.2 only, it does not happen with 4.1.4/4.1.5!
  (or maybe try to add an updateGeometry() call somewhere as well; JSpitzm).

* All label and button texts in the Qt4 dialogs are not translated.

  FIXED (MGerz 2006-11-07)

* Some English menu items don't have a '&' character. (box, date, paste...)

  FIXED (MGerz 2006-11-07). I added shortcut whereever possible.

* When changing the toolbar settings in the right-button context menu of a 
  visible toolbar, the modified settings are not considered for session management
  
  REPLACED with a new entry, popup disabled (Peter 2006-11-09)

* Toolbars always show on the top of the screen, even though they are set to
  "bottom" in the ui file (Joost 3/11/06).

  FIXED: use the defaul.ui value only when there is no valid position stored 
         (1st start of lyx)  (Peter 7/11/2006)

* Window positions are not remembered correctly. Each time a window is openend
  window again it has moved towards the bottom of the screen. (Joost 3/11/06)

  FIXED (Peter 8/11/2006)

* Special handling of [[...]] in text messages is disabled in messages.C
  FIXED (Georg 2006-11-12)

* broken signal/slot connection:
  Object::connect: No such signal LengthCombo::selectionChanged(LyXLength::UNIT)
  Object::connect:  (sender name:   'unitCO')
  Object::connect:  (receiver name: 'QVSpaceUi')

  FIXED (JSpitzm 2006-11-12)

* Cursor is still not visible on MAC Bennett (3/11/06).
  FIXED (Abdel 2006-11-13)

* crash on Windows/Mac
  1. new document
  2. insert List/TOC->Bibtex Bilio
  3. add a bibliography
  4. View Source ->crash
  FIXED (Peter 2006-11-14)

* In the TOC dialog, switching between the different TOC types (TOC, Table,
  Float, etc.) is broken.
  FIXED (Ugras)

* In the TOC dialog, the slider for altering the display level is
  non-functional (not implemented).
  FIXED (Ugras 2006-11-17)

* The correct list is not selected when right-clicking on a LOF or
  LOT inset.
  FIXED (Ugras 2006-11-17)

* When selecting a type which *is* already selected, the content in the 
  browser window vanishes
  FIXED (Ugras 2006-11-17)

* TOC crashes (simply make a few sections, subsections, sections; then add TOC
  before all sections and click on the left button)
  FIXED (Abdel, sometimes in november 2006).

* Items in the TOC cannot be moved using drag & drop (Joost 4/11/06).
  WONTFIX (Abdel 2006-11-17): at least not for 1.5.0, this is just candy anyway.

* M-x is broken (does not bring up the minibuffer).
  FIXED (Bo, 2006-11-18): set toolbar flag in display function.

* open a file; mark with the mouse and scroll; assert will fail:
  FIXED (Abdel 2006-11-20): side effect of updateMetrics() cleanup.
  
* Selection highlighting is broken. Test case: two paragraphs with "Hello"
  and "World"; move cursor past "Wor", press Shift+Up 
  FIXED (Abdel 2006-11-20): side effect of updateMetrics() cleanup.
  
* Mac Crash (Bennett 3/11/06):
  On launch from GUI (by double-clicking on the LyX icon). As I reported before,
  this happens only when using the GUI; I can successfully start LyX from the
  Terminal, with or without gdb. Hence the only debug information I get is this,
  printed out in Console.app when I try launching from the GUI (note that the
  number changes everytime):

  Wrong command line option `-psn_0_182321153'. Exiting.

  Hint from Andreas Vox: LyX must accept any option starting with '-psn' and
  pass it oon to the Qt initialisation. On Mac this gives the app a link to the
  Window system.
  FIXED (Abdel 2006-11-25): Arguments are now passed to QApplication.
  
* In the math control panel, "Detach panel" is broken (only 1 button is
  visible in the detached panel).
  FIXED (Edwin/Ugras 2006-11-XX)
  
* Command completion in the minibuffer shows a huge blank area below the proposed
  commands. Clicking in that empty area crashes LyX.
  FIXED (????)
 
* Copy/paste using middle mouse button inserts musical notes.
  FIXED (Abdel 2006-11): Confirmed by Michael who couldn't reproduce on SuSE Linux 9.3)

* new document; insert note; place cursor in front of the note; activate change tracking;
  press delete => assertion failed
  FIXED (JMarc 2006-11)

* new document; insert note; insert "hello" into note; place the cursor at the beginning of the note;
  activate change tracking; press backspace => seg fault
  FIXED (Michael 2006-11-25)

* Mac Crash On quit (Bennett).
  FIXED (Peter 2006-11-20)

* Drawing oddities on MAC (Bennett 3/11/06):
  Lines occasionally overlapping vertically, math characters not properly
  aligned vertically.
  FIXED (JMarc 2006-11).

* Icons in the toolbars do not have the correct size, they are stretched a few
  pixels compared to 1.4. This makes the images look jagged and the initial
  window size has also become to small to show the whole toolbar
  (Joost 4/11/06). See also the math panel buttons entry above.
  FIXED (Peter, 2006-11-28)

* The -geometry option doesn't work on Windows (it did in 1.4.x)
  c:\> lyx-qt4.exe -geometry 800x600+100+30
  Wrong command line option `-geometry'. Exiting.
  FIXED (Peter, 2006-11-29)

* When I "Save as..." in /tmp, I get a Backup error popup about non writable 
  /tmp, which is obviously not true.  The file is there, and if I try to Save
  as again, I get the overwrite popup warning twice: once in English, once 
  in French. (J. P. Chretien)
  FIXED (Michael (found the problem), Georg (fix), 2006-11-30)

* It is ridiculous that you have to call configure with --with-frontend=qt4.
  The existance of config/qt.m4 does not make much sense either.
  The first one is FIXED, the second WONTFIX (JMarc 07-12-2006)

* Open de_Intro.lyx => The footnote text in the title section exceeds the
  footnote frame
  FIXED (Enrico 2006-12-09). This was due to wrong metrics for small caps.

* Spell checking cannot be invoked a second time.
  FIXED (Georg 2006-12-10). Abdel accidentally committed some test code in
  revision 14970 which I reverted.

* The first time the spell checker is started, an empty window shown instead
  of the first misspelled word.
  FIXED (Georg 2006-12-10). This bug had the same resaon as the previous one.

* Create a new document; enter a few chars; press return; click on the previous paragraph 
  with mouse to change the focus: lyx crashes. (happens on Win XP SP2, 
  MSVC 2005 Prof., Scons) 
  FIXED (JSpitzm 2006-12-11)
