23 * When I "Save as..." in /tmp, I get a Backup error popup about non writable
24 /tmp, which is obviously not true. The file is there, and if I try to Save
25 as again, I get the overwrite popup warning twice: once in English, once
26 in French. (J. P. Chretien)
28 * Loading de_Userguide.lyx results in two parse errors:
29 Paragraph ended in line 21206
31 Paragraph ended in line 21301
33 I don't know if that is a lyx2lyx or LyX problem. LyX 1.4 can read the file.
36 SPELL CHECKING (Joost 4/11/06)
38 * Spell checking cannot be invoked a second time.
40 * The first time the spell checker is started, an empty window shown instead
41 of the first misspelled word.
43 * Words with umlauts or accents do not arrive as a whole word in the spell
49 * In TOC, the buttons "Up", "Down", "Promote", and "Demote" are not
50 self-explaining. Why don't we group them in two pairs: Section Up/Down, Level
51 Up/Down? The arrangement of the buttons may also give some hint to the user.
53 * The items in the treeview are editable
55 * When content (sections/captions) is changed, the toc/lof/lot is not properly
57 Abdel 2006-11-17: This one is not as simple as it seems as it involves a
58 TocBackend update at each keystroke. Unless we manage to update a specific
59 TocItem, this will be a WONTFIX for 1.5.0.
64 * when opening an already opened document (or a document with newer backup),
65 the mouse pointer turns into a clock, although it waits for confirmation
67 * If you try to view a document as postscript that cannot be typeset because
68 of LaTeX errors and export to LaTeX afterwards you will get the old error
69 list again, although the export succeded.
74 * In the math control panel, switching between different "functions" is broken
75 (retry a couple of times).
77 * In the math control panel, there is no icon for "Set Math Font".
79 * In the math control panel, the buttons are too small.
80 The reason is probably that qt resizes the icons so that they fit into the
81 button, leaving some margin. This leads to different scales for each icon.
82 qt3 did not resize the icons. Can this be set in qt4, too?
87 * The visual table size selection on the the "Insert Table" dialog is gone
90 * The UI for bullet selection in the documents settings looks weird
92 There is a big listbox just to select one of the four levels.
93 Isn't this supposed to be a drop-down list or something like that?
95 * The bullet selection widget shows the bullets in 5 columns (instead of 6)
96 for me, and hence does not fit into the window.
100 MULTIPLE WINDOWS / DOCUMENTS
102 * There are cursor problems when the same document is opened in two windows
105 Information from Abdel:
106 Yes, this is the famous dEPM bug (delete Empty Paragraph Mechanism).
107 There are two ways to fix that:
108 1) the correct way: fix the dEPM to not invalidate the cursor.
109 2) the easy way: disable the cursor on focus out event and re-enable it at
110 focus in event and jump the saved position (at focus out).
112 * There should be a close button on the tabs (Joost 3/11/06).
113 There is now a Qt feature request:
114 http://www.trolltech.com/developer/task-tracker/index_html?id=137891&method=entry
117 TOOLBARS & MINIBUFFER
119 * When toolbars are hidden, they pop up again after clicking on the document
120 area (Joost 4/11/06).
122 * Icons in the toolbars do not have the correct size, they are stretched a few
123 pixels compared to 1.4. This makes the images look jagged and the initial
124 window size has also become to small to show the whole toolbar
125 (Joost 4/11/06). See also the math panel buttons entry above.
127 * TODO toolbar popup menu, currently disabled (Peter 9/11/06)
132 * edit->text style->capitalize/lower/upper case doesn't work due to change
133 tracking-related changes.
135 * Copy/paste using middle mouse button inserts musical notes.
137 * new document; insert note; place cursor in front of the note; activate change tracking;

174 * No change bar is given in LaTeX output if (only) the par break has changed
176 * In tables, cut & paste (complete cells) do not support change tracking
178 * When accepting or rejecting changes, paragraphs with deleted par breaks are
179 not merged in nested text insets
181 * When accepting a change, LyX may hang (same as in 1.4.3)
186 * environments when using czech translation doesnt work: e.g.
187 itemize("Polozka") -> ERROR (layoutSelected): layout not found! (P. Sanda)
190 PAINTING & PERFORMANCE
192 * Too much painting 2 (Edwin 3/11/2006): There is also a lot of painting going
193 on when selecting text. When selecting a word the whole screen is repainted.
194 PARTLY FIXED (Abdel 2006-11-20): there's a full repaint only when the mouse is
195 released. More to come in this area.
197 * Too much painting 1 (Edwin 3/11/2006): when i click in the workarea (to put
198 the cursor in another part of the text) the screen is repainted *twice*
199 whereas it seems to me that no repainting is necessary at all.
200 PARTLY FIXED (Abdel 2006-11-20): except for math insets.
202 * Too much painting 3 (Edwin 3/11/2006): the screen is repainted even when the
203 selection does not change (moving the mouse with the left button pushed down
204 always triggers a repaint).
205 PARTLY FIXED (Abdel 2006-11-20): When within the main text inset only the
206 current line is repainted.
208 * The cursor is not L-shaped for foreign languages
210 * Slowness on MAC 1 (Bennett 3/11/06):
211 There seems to be a fraction of a second lag between when I press a key and
212 when the letter appears on screen -- but the time lag doesn't obviously vary
213 with the amount of text on the screen (as was the case previously). Right now,
214 the speed of normal text entry makes LyX-1.5 usable on my
215 not-fast-but-still-not-outdated computer. (Not sure how it would be on my
216 slow-but-still-usable laptop.)
218 * Slowness on MAC 2 (Bennett 3/11/06):
219 Speed is still an issue typing in insets: noticeable lag between typing and
220 text appearing on screen. This does not seem to be compounded by having nested
221 insets, and it seems to be compounded only a little by the amount of text in
222 the inset. (This is especially a problem in math environments.)
223 PARTLY FIXED (Abdel 2006-11-20): except for math insets.
225 * Slowness on MAC 3 (Bennett 3/11/06): Some operations that with 1.4 are
226 pretty much instantaneous (inserting a footnote, dragging the mouse, switching
227 to LyX from another application, opening dialogs, etc.) take quite a long time
230 * Some math symbols are not displayed (from Enrico Forestieri)
231 I noticed that some math symbols are not shown on screen. This seems
232 to be platform dependent. The following is a table illustrating the
233 situation on three different platforms. Here "no" means that the
234 symbol is not shown on screen (the symbol is invisible but occupies
235 space: it is as a sort of \phantom), and "yes" that it is shown.
236 ---------------------------------------
237 Symbol Linux Solaris Cygwin
238 ---------------------------------------
244 \spadesuit(*) yes no yes
245 ---------------------------------------
246 (*) On solaris, a square is shown on screen instead of nothing.
247 Further comments from Georg: This is probably a qt4 font drawing problem,
248 since \Omega works fine in 1.4.3, and my debugging results showed that the
249 correct font is found and used (cmr10).
254 * It is ridiculous that you have to call configure with --with-frontend=qt4.
255 The existance of config/qt.m4 does not make much sense either.
260 * Drawing oddities on MAC (Bennett 3/11/06):
261 Lines occasionally overlapping vertically, math characters not properly
264 * Many issues with toolbars on MAC (Bennett 3/11/06):
265 Most obvious of which are that icons are spaced too widely and that changes in
266 the visibility of the toolbars with the GUI do not stick after the screen is
269 * Many issue with dialogs on MAC (Bennett 3/11/06):
270 Most obviously: the Preferences dialog -- which can only be accessed now via
271 keyboard command, not from the menu -- appears initially too small and must be
272 resized; not possible to select buttons with the keyboard).
274 The prefs dialog size should be better now. See below (JSpitzm-2006-11-07).
276 * Some oddities with View menu on MAC (Bennett 3/11/06): DVI does not appear
277 in the menu, even though a converter and viewer are defined in Preferences.
279 * Menu bar disappears on MAC (instead of being disabled) when dialogs appear.
282 * Mac Crash On quit (Bennett).

313 **********************************************************************
318 * Performance on Windows is bad. On my system, scrolling the User Guide takes
319 10 seconds with LyX 1.4 and more than 30 seconds with LyX 1.5.
321 FIXED (Abdel 04/11/06): This was due to spurious message in QLPainter.C,
323 * When I have the same document in two windows, only the last selected paragraph
324 in one of the windows gets updated.
326 FIXED (Abdel 04/11/06): This was due my singlePar optimization. With my last
327 commit, the optimization is enabled only if the WorkArea has the focus.
329 * No icon for "note-next" in the "review" toolbar.
331 ADDED (JSpitzm 2006-11-04).
333 * Branches gui broken (buttons do nothing).
335 FIXED (JSpitzm 2006-11-04).
337 * The title bar does not contain the document name when a new window is opened
340 FIXED (Abdel 05/11/06): This was due to "last_title" being a static variable
341 in LyXView::updateWindowTitle() and also due to a potential bug in Qt:
342 an update command to the window title seems to be ignored up until the window
345 * src/frontends/qt4/ui/QCitationUi.ui:70 "&Selected citations:" should be
346 "&Selected Citations:".
348 FIXED (MGerz 2006-11-05)
350 * In the "Math Delimiters" dialog, there is no need to repeat the term "Size"
351 for all values in the selection box; the label is already named "Size"
353 FIXED (MGerz 2006-11-05)
355 * If you open Document>Settings... or Tools>Preferences... for the first time,
356 the dialog is much too small to show its content; if you invoke it the second
357 time, everything is fine.
359 This happens with qt 4.2.1 only, it does not happen with 4.1.4/4.1.5!
361 FIXED (JSpitzm-2006-11-06): force updateGeometry() after the panelstack has
362 been created (with Qt >= 4.2 only). A brute method, but it works.
364 * If you open Edit>Test Style... for the first time, the choice text for
365 "Never Toggled>Size" doesn't fit in the selection box (note that in German,
366 texts are a bit longer than in English). Interestingly, if you invoke the
367 dialog a second time, its button sizes are adjusted to their content.
369 WONTFIX: This happens with qt >= 4.2 only, it does not happen with 4.1.4/4.1.5!
370 (or maybe try to add an updateGeometry() call somewhere as well; JSpitzm).
372 * All label and button texts in the Qt4 dialogs are not translated.
374 FIXED (MGerz 2006-11-07)
376 * Some English menu items don't have a '&' character. (box, date, paste...)
378 FIXED (MGerz 2006-11-07). I added shortcut whereever possible.
380 * When changing the toolbar settings in the right-button context menu of a
381 visible toolbar, the modified settings are not considered for session management
383 REPLACED with a new entry, popup disabled (Peter 2006-11-09)
385 * Toolbars always show on the top of the screen, even though they are set to
386 "bottom" in the ui file (Joost 3/11/06).
388 FIXED: use the defaul.ui value only when there is no valid position stored
389 (1st start of lyx) (Peter 7/11/2006)
391 * Window positions are not remembered correctly. Each time a window is openend
392 window again it has moved towards the bottom of the screen. (Joost 3/11/06)
394 FIXED (Peter 8/11/2006)
396 * Special handling of [[...]] in text messages is disabled in messages.C
397 FIXED (Georg 2006-11-12)
399 * broken signal/slot connection:
400 Object::connect: No such signal LengthCombo::selectionChanged(LyXLength::UNIT)
401 Object::connect: (sender name: 'unitCO')
402 Object::connect: (receiver name: 'QVSpaceUi')
404 FIXED (JSpitzm 2006-11-12)
406 * Cursor is still not visible on MAC Bennett (3/11/06).
407 FIXED (Abdel 2006-11-13)
409 * crash on Windows/Mac
411 2. insert List/TOC->Bibtex Bilio
412 3. add a bibliography
413 4. View Source ->crash
414 FIXED (Peter 2006-11-14)
416 * In the TOC dialog, switching between the different TOC types (TOC, Table,
417 Float, etc.) is broken.
420 * In the TOC dialog, the slider for altering the display level is
421 non-functional (not implemented).
422 FIXED (Ugras 2006-11-17)
424 * The correct list is not selected when right-clicking on a LOF or
426 FIXED (Ugras 2006-11-17)
428 * When selecting a type which *is* already selected, the content in the
429 browser window vanishes
430 FIXED (Ugras 2006-11-17)
432 * TOC crashes (simply make a few sections, subsections, sections; then add TOC
433 before all sections and click on the left button)
434 FIXED (Abdel, sometimes in november 2006).
436 * Items in the TOC cannot be moved using drag & drop (Joost 4/11/06).
437 WONTFIX (Abdel 2006-11-17): at least not for 1.5.0, this is just candy anyway.
439 * M-x is broken (does not bring up the minibuffer).
440 FIXED (Bo, 2006-11-18): set toolbar flag in display function.
442 * open a file; mark with the mouse and scroll; assert will fail:
443 FIXED (Abdel 2006-11-20): side effect of updateMetrics() cleanup.
445 * Selection highlighting is broken. Test case: two paragraphs with "Hello"
446 and "World"; move cursor past "Wor", press Shift+Up
447 FIXED (Abdel 2006-11-20): side effect of updateMetrics() cleanup.
449 * Mac Crash (Bennett 3/11/06):
450 On launch from GUI (by double-clicking on the LyX icon). As I reported before,
451 this happens only when using the GUI; I can successfully start LyX from the
452 Terminal, with or without gdb. Hence the only debug information I get is this,
453 printed out in Console.app when I try launching from the GUI (note that the
454 number changes everytime):
456 Wrong command line option `-psn_0_182321153'. Exiting.
458 Hint from Andreas Vox: LyX must accept any option starting with '-psn' and
459 pass it oon to the Qt initialisation. On Mac this gives the app a link to the
461 FIXED (Abdel 2006-11-25): Arguments are now passed to QApplication.
463 * In the math control panel, "Detach panel" is broken (only 1 button is
464 visible in the detached panel).
465 FIXED (Edwin/Ugras 2006-11-XX)
467 * Command completion in the minibuffer shows a huge blank area below the proposed
468 commands. Clicking in that empty area crashes LyX.
