Debugging spree:
----------------

Rules:
1. bugs that aim for 1.5.0 should be listed here.
2. whoever fixes a bug sign his name before the bug and move it to the end of
   this file, along with a lyx-devel announcement.
3. we need to figure out a price for the champion (and second place).


BUGS:
-----

SPELL CHECKING (Joost 4/11/06)

* Spell checking cannot be invoked a second time.

* The first time the spell checker is started, an empty window shown instead
of the first misspelled word.


TABLE OF CONTENTS

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

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

* TOC crashes (simply make a few sections, subsections, sections; then add TOC
before all sections and click on the left button)

* Items in the TOC cannot be moved using drag & drop (Joost 4/11/06).

* 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.


DIALOGS

* 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.

* 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.

* 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)


MATH CONTROL PANEL

* In the math control panel, "Detach panel" is broken (only 1 button is
visible in the detached panel).

* In the math control panel, switching between different "functions" is broken
(retry a couple of times).

- In the math control panel, there is no icon for "Set Math Font".

- In the math control panel, the buttons are too small.

- 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"


OTHER PANELS

* The visual table size selection on the the "Insert Table" dialog is 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?


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).

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

* There should be a close button on the tabs (Joost 3/11/06).


TOOLBARS

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

* When toolbars are hidden, they pop up again after clicking on the document
area (Joost 4/11/06).

* 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).


EDITING

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


MENUS

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

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


PAINING & PERFORMANCE

* 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.

* 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.

* 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).

* 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.)

* 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.


MAC OS X

* Cursor is still not visible on MAC Bennett (3/11/06).

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

* 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):
Mmost 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).

* 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.

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

* 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.

* Mac Crash On quit (Bennett).

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. Although I have
a modern computer, it all feels very slow.

FIXED (Abdel 04/10/06): This was due to spurious message in QLPainter.C, I've
put that in Debug::PAINTING, so 1.5 is faster than 1.4 on Windows XP on my 3
years old laptop (18s for the UserGuide test).

* The multi-window thing is broken. When I have the same document in two
windows, only the last selected paragraph in one of the windows gets updated.

FIXED (Abdel 04/10/06): 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).
