Parley Practice Rewrite for KDE 4.5

Work on the parley practice happens in a branch here: Browse WebSVN online

Check it out: svn co svn://anonsvn.kde.org/home/kde/branches/work/parley-practice/


  • DONE: remove old practice code F
  • TODO: does Paraphrase make any sense at all? no - remove paraphrase - it is not used in any single document we could find
  • TODO: remove Antonym completely
  • DISCUSS: timeouts during practice ???


  • TODO: get rid of current way of handling them in the lib? BIC!!!???!!!
  • TODO: use a stringlist instead
  • TODO: make it possible to edit them in the table - how to separate two of them? semicolon?
  • TODO: change/rewrite dock widget
  • DISCUSS: practice options (is this really really needed?):
  • DONE: Check synonyms as part of written practice (BEN_SCHL)
    • DONE: accept any synonym as correct (BEN_SCHL)
    • DONE: ask to enter all synonyms (BEN_SCHL)
    • DONE: show already entered synonyms in list (BEN_SCHL)
    • DONE: ask until the exact word that is wanted is there, but don't count other synonyms as wrong on the way there (BEN_SCHL)
    • DONE: Check user options if he really wanted synonyms to be counted as correct by now we always accept them as correct (BEN_SCHL)
    • Let other modes benefit from synonyms. Maybe similar to the hint button show a synonym if it exist?
    • DONE: If in written mode a synonym was entered, check if that synonym is in this practice mode and increase its good count ? (BEN_SCHL)

LaTeX support

  • TODO: integrate LaTeX in written and flash card practice modes
  • TODO: poslish and test
  • TODO add documentation to manual
  • do nothing on empty string
  • limit max size of widget


  • TODO: implement rendering of scaled and cropped background
  • DONE dani_l: border-foo-repeat (stuff like fluffy bunny doesn't work that well if scaled...)
  • TODO: make it possible for the boxes widget to be scaled (and change the layout so that it can get more space)

Configure Practice

  • TODO: threshold: word types are broken here?

Parley practice settings advanced.png

Notes Advanced page:

  • TODO: Time limits: only let the user select if the time limit is active, use show solution after answering
  • TODO: enable button xyz: not applicable any more, only the hint button, so remove them from the ui file
  • TODO: rearrange the widgets in the advanced page
  • IDEA/TODO: maybe it would make sense to put the most common options into the statistics page that is shown before practice is started
    • maybe replace the checkboxes again with radio buttons -> it's so easy to change now
    • only show one bar of grades - the one that corresponds to the current language selection

Parley start statistics with options.png

  • TODO: add grammar grade visualisation

Completely Missing

Still missing are:

  • TODO: Vocabulary test (school like) with good summary and "grade"
    • no button for hints
    • add buttons to "go back and forth"
    • don't show if the answer was right
    • DISCUSS: do we want to have some type of "grade" and if yes, how should it be calculated?

Comparison Forms

You know? Adjectives and adverbs - words that describe other words.

  • green/red for right answers make right answers disabled so they can't be screwed up again
  • URGENT show solution if wrong
  • URGENT do not randomly skip words when answer was wrong

Flash Card

  • focus on continue button is not set when showing the first card, from then on it works
    • I don't understand why it doesn't work after having a quick look (Frederik)
  • TODO - EASY: add sound and pronunciation, same as in written mode, only needs code in flashcardmodewidget.cpp to be changed

Multiple Choice

  • DONE dani_l: hotkeys (maybe in menu? even configurable??) for the choices: 1 for first, 2 for second...
    • TODO - KDE 4.6: use kactions and make sure they are configurable
  • TODO - KDE 4.6: it would be nice to get rid of the radio buttons in favor of having something else maybe - a list? something that looks nicer
  • Adding sound pronunciation and comment would be nice here too


  • There is a class like this, "answervalidator.cpp" but it's ugly old and eats kittens. Cleaning it up would be ok. Things like word similarity are in there.
    • Moved some of the code to the new WrittenPracticeValidator class maybe move more funtionality there ?
  • how far do we want to go when comparing answers? what feedback should the user get?
    • you made a spelling mistake (this can be done by running spellcheckers and comparing what they suggest for a word with the solution)
    • you wrote nonsense


All Practice Modes

  • DISCUSS: define our terminology, e.g. is it grade or box, answer or solution, correct or right, incorrect or wrong etc.
  • TODO: implement support for showing pronunciation for every practice frontend
  • TODO: implement support for sound for every practice frontend
  • TODO: add a "Auto-play sound" option to the practice settings and implement it
  • TODO KDE 4.6: sound - rename "enable sound" to "autoplay sound" and implement it


Grades are equivalent to boxes (leitner), they are:

  • 0 not practiced
  • 1 lowest level
  • ...
  • 7 best level
  • Words are answered correctly:
    • a correct answer gives grade += 1
    • a word that has been answered correctly is not asked again
  • Words are answered wrong:
    • a wrong answer gives grade = 1 (reset to lowest level). Wrong anserws are:
      • If a hint message has been used (may change policy here later if it doesn't work out)
      • If an accent and/or capitalisation mistake was made (might be accepted as right if the option is chosen in the config)
    • If answer stays the same after enter is pressed a second time assume the user doesn't know the answer and continue.
    • Just print a different message if the user corrected himself and the answer was right
    • words that were incorrectly answered will come up again until they are answered correctly (or the practice is stopped)
    • DISCUSS: when a word is answered after being answered wrong before, it ends up on level 2, if the practice is stopped before, it stays in level 1 (Leitner says it stays in 1 ?)

  • TODO: implement grading as described above and make sure it works in all modes
  • TODO: Respect Leitner option to ask for the correct answer three times in a row.
  • DISCUSS: If you answer an unknown word wrong or right doesn't matter as by definition above wrong words get set to level 1 (from 0) and right words get increased to 1 (from 0). I changed that correct new words end up in level 2 ? (BEN_SCHL)
  • DISCUSS: what happens when practicing with multiple modes? does only the last mode affect the grading? make in configurable? (DOES THIS STILL APPLY?)
  • DISCUSS: find out if restricting the grading for each mode makes sense (e.g. saying "if i practice in multiple choice, the word can only rise up to grade 3")
    • TODO: figure out a sane way to configure this or give different grades for each practice mode ?
  • TODO: pass in 3 int from backend to frontend: current, good, bad (so that the selection of right/wrong can be previewed correctly)
    • note: basically it is already implemented, but in a quick and in some (most?) cases wrong way. we probably need some TestEntry::gradeIfWrong() etc or something like that

Summary Page (after practice is finished)

  • TODO for some practice modes the result is complete nonsense - eg conjugations show the normal words in the summary
  • TODO fregl: add a button to print a list with $number words you should practice

General (not practice related)

  • STILL VALID?: New rows are appended when pressing enter in the row above the last one, not in the last one - Qt 4.6 regression?
  • TODO: changes in dock widgets are not reflected in table -> model needs to emit dataChanged for the view to update (not working since the editing happens without models knowledge)
  • TODO: table: add column for grades (including combo box for changing the grade)
  • TODO: summary dock widget: make word type work
    • setting works
    • instead of the normal model use a flat list model (proxy would work)
  • TODO: remove leitner box classes
  • TODO: get rid of old kDebug() messages that don't make sense out of context
  • TODO: check if the column visibility is saved correctly in all cases
  • TODO fregl: there is a broken version of the 5 language document in the files on edu.kde.org (and there should be a *version with and without* images which you can clearly separate from each other, right?)
  • Settings
    • TODO: the languages that will be practiced should be per document, not global
    • TODO: other practice options should probably be per document as well
  • TODO: implement undo support
  • TODO: frederik be ashamed! Danish document -> 4000 words to sublessons a 20 doesn't work
  • TODO: creating a new document: title is not carried over for root lesson and window title
  • big todo: configurable special chars per language - come with language definition - configurable hotkey ...
  • I also found a bug, when deselecting the main lesson, it resets the title to "0". When clicking it again (to select all sublessons), it renames itself to "2".

Word types

  • TODO: newly created sub word types should inherit their parent's grammar type -> Frederik?
  • TODO do not show word types in the table when clicking them (maybe on right click menu?)

Profiles and config and zip

  • DISCUSS: Instead of using current kvtml files, use the same with compression
  • add images, sound and other media into the zip file

Regressions in trunk

  • Title is broken (documents show up with 0 as title, chainging root lesson behaves weird, it doesn't get saved)
  • TODO fregl: Auto-save in practice mode


(Frederik does all of this unless someone else wants to punish himself)

  • Comparison forms: use keduvoctext for forms (make grades possible)
  • make grades for articles possible

Stuff to discuss today

  • artwork
    • what/how/format
    • who
    • write request with lots of screenshots?
  • correct/wrong states, it it ok how they are currently implemented (especially in written mode)
    • great, but: longer ? in written (see above)
  • what grammar modes do we need and how can they be implemented
    • can we reuse/extend our frontend/backend modes?
  • grading for grammar training
  • create example document(s) making use of all our advanced features for testing
    • grammar training
    • multiple choice options
    • two images per entry, pronunciation, sound
    • ...
  • blockers before merging the branch back to trunk
  • timeline for merging, release schedule
  • synonym/antonym: what to keep? what about semicolons?

Usability session with Leinir

Dan, Lydia, Daniel and Frederik sat down in Randa and these are some notes on usability.

Comments from Lydia:

Start Practice

  • table is big and in your face, but maybe that is ok
  • check boxes should be tri-state - parent lessons should be half-checked if only some of their children are selected
  • only show the relevant column with grades instead of all of them
  • do not offer to start practices that contain 0 words! it's borked!


  • flash cards: change continue button to "show backside"
  • pic placeholder is ugly in default theme
  • progressbar should maybe start counting at 1
  • label: "I did not know it" "I know it" -- or "Did you know the answer?": "yes" - "no"
  • mixed letters are getting grey on grey -> generally font color is problematic
  • Multiple choice needs shortcuts (key 1-5 for example) and continue button should be disabled until a choice is selected.
  • conjugation mode: "Enter all conjugation forms" is a silly string and should be removed.

Document Properties

  • get email from kuser-something
  • categories: test preparation makes no sense as category
  • tooltip for checkboxes
  • remove flags for languages

Comments from Dan:

  • create video tutorials

Start Screen

  • hide "last opened" string if list is empty
  • title could be "Parley - Vocabulary Trainer" use kqtitlewidget


  • subtypes in word types should always get their parent's type by default

Start Practice

  • indent tenses below radio buttons
  • always show tenses (both Daniel and Frederik are against this)
  • remove status bar
  • remove tree indicator from tense selection
  • enable practice checkbox by default in file dialog (depending on current component)
  • remove "Editor" from toolbar, make sure it is in the menu though


  • Since May 19th: Soft Message Freeze
    • NO NEW STRINGS, NO STRING CHANGES ANY MORE (ask Frederik if you need to change strings and let him take the flames)
  • June 2nd: Documentation/Handbook Freeze
    • Have an updated documentation, work with Burkhart to get it from userbase to docbook
