Parley Practice NG 23rd attempt

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
  • TODO: find an icon for stop practice (toolbar)
    • idea: use the start practice with media-stop instead of media-play
  • 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?):
    • accept any synonym as correct (BEN_SCHL)
    • ask to enter all synonyms (BEN_SCHL)
    • show already entered synonyms in list (BEN_SCHL)
    • ask until the exact word that is wanted is there, but don't count other synonyms as wrong on the way there (BEN_SCHL)

LaTeX support

  • TODO: write a class to convert latex code to images, with error handling etc
  • TODO: integrate LaTeX in written and flash card practice modes
  • TODO: write a dock widget to support the user editing latex (line edit, preview, checkbox to toggle math mode?)

Configure Practice

Main page:

  • DONE: Currently check boxes and radio buttons are shown ->remove radios F
  • DONE: move multiple choice options to advanced - Kolia
  • DONE: move checkboxes in Practice->Options to Advanced page in config dialog - Kolia
  • DISCUSS: Tenses - where should they be selected? only needed for conjugation practice
  • DONE: language selection: instead of having two lists, just have one list containing "French → German" and "German → French" (Kolia) I'm sorry, I just did it - Frederik
    • check if with 2 languages are always in the right order now!

The layout could be like this:

  • TODO: it would be nice to replace the checkboxes by listviews with multi selection and icons (and optionally drag and drop to change the order)

Other pages:

  • TODO: threshold: word types are broken here?

Notes Advanced page:

  • DONE: Remove direction switching checkbox until implemented - Kolia
  • 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
  • TODO: comparison forms: make no distinction between adjectives and adverbs
  • 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

Completely Missing

Still missing are:

  • TODO: Conjugations
  • 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?

Easy ones reusing the written front end should be:

  • TODO: Example sentences

Article/Gender of Nouns

Two cases: we have the articles in the grammar section or we don't Example: German die Flasche is female == bottle

  • a) We know the articles, this is presented:
    • bottle
      • der Flasche
      • die Flasche
      • das Flasche
  • b) We don't know the articles
    • bottle
      • Flasche is masculine
      • Flasche is feminine
      • Flasche is neuter


  • definite articles by default, fall back to indefinite

For the implementation: just use the Multiple choice front end and subclass (if possible, otherwise make it possible!) the multiple choice backend

Comparison Forms

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


  • unordentlich
  • Absolute: chaotic (the base form)
  • Comparative: [more chaotic] (user inputs more chaotic in line edit)
  • Superlative: [the most chaotic] (user inputs most chaotic in line edit)


  • caption (the word in the other language)
  • 3 labels and line edits

Flash Card

  • DONE dani_l: replace [Continue] with [I didn't know the answer][I knew the answer] in flash card mode

Multiple Choice

  • DONE Kolia: Unset the selected choice after an answer (radio button)
  • DISCUSS: Showing the "I knew it"/"Did not know it" below the other radios looks bad
    • DONE dani_l: implement a toggle under the ✓/✗ image
      • DISCUSS: do we like it?
  • DONE Kolia: Make number of multiple choice answers configurable in the config practice dialog
  • keyboard focus?!?! if I press enter and no choice is selected, it will always be wrong
  • hotkeys (maybe in menu? even configurable??) for the choices: 1 for first, 2 for second...
    • use kactions
  • TODO: continue when a radio button is selected


  • DONE: Hint needs to be implemented in a sane way (now it shows the solution directly) - done (Frederik)
  • DONE: Feedback - when a new word is shown, it still says "Your answer was wrong" - done (Frederik)
  • TODO: Ignore accent / capitzalisation mistakes is not implemented currently (BEN_SCHL)
  • TODO: make sure that "I did (not) know it" actually does the right thing
  • TODO: I think I just had an empty word shown - make sure they are filtered away
  • TODO: Create a class that does voodoo on strings to correct answers: (BEN_SCHL)
    • Takes into account the options above (accent/capitalisation)
    • 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.
    • 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
      • you have the accents all wrong
    • how do we get this kind of feedback from the class to the ui?
  • TODO when pressing enter and the input is empty, directly continue to solution. don't ask for another try.
  • TODO dani_l: only show right/wrong when the solution is shown

All Practice Modes

  • TODO: every word that was answered correctly is shown as "right on first attempt" in summary - no way to get anything wrong :D maybe change that...
  • TODO: remove statistics that don't make sense any more from the TestEntryManager (like "skip known")
  • TODO: feedback text: not "wrong idiot", not "I fear this was wrong.." but good sentences
  • TODO: set grade to 1 when a word was answered incorrectly
  • DISCUSS: define our terminology, e.g. is it grade or box, answer or solution, correct or right, incorrect or wrong etc.
  • TODO: fix spacing and layouting issues in the ui


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

  • 0 not practiced
  • 1 lowest level
  • ...
  • 7 best level

Words can be answered correctly or wrong.

  • a correct answer gives grade += 1
  • a wrong answer gives grade = 1 (reset to lowest level)
  • a word that has been answered correctly is not asked again
  • words that were incorrectly answered will come up again until they are answered correctly (or the practice is stopped)
  • 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

When answering in written mode, the user gets a chance to correct herself if the first answer was not right. She can edit the answer immediately after pressing enter again. If no changes were made, we assume the user doesn't know the answer and show the "wrong answer, continue" state. If on the other hand the answer is changed into the right answer, we still count it as wrong. The feedback text reads something like "Your answer was right, but you needed more than one attempt to get there.".

A word is wrong when

  • the user enters anything but the right answer in the first attempt (first pressing enter is all that counts)
  • hint means it's wrong (may change policy here later if it doesn't work out)
  • accent and capitalisation might be accepted as right if the option is chosen in the config
  • TODO: implement grading as described above and make sure it works in all modes
  • DISCUSS: what happens when practicing with multiple modes? does only the last mode affect the grading? make in configurable?
  • 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
  • TODO: pass in 3 int from backend to frontend: current, good, bad (so that the selection of right/wrong can be previewed correctly)

Result States

  • User hasn't entered anything
    • Status image: ?
    • Status image toggle: inactive
    • Line edit: black
    • Counted as: nothing yet
  • User entered a wrong solution
    • Status image: ✗
    • Status image toggle: active (?)
    • Line edit: black
    • Counted as: nothing yet
  • User entered a wrong solution, got feedback and pressed enter without changes
    • Status image: ✗
    • Status image toggle: active
    • Line edit: red, disabled (Solution is shown)
    • Counted as: wrong
  • User entered wrong solution(s), got feedback and entered the correct solution
    • Status image: ✓ (?)
    • Status image toggle: active (doesn't make sense!)
    • Line edit: green, disabled (Solution is shown)
    • Counted as: wrong

    • Status image: ✓
    • Status image toggle: active
    • Line edit: green, disabled (Solution is shown)

    • Status image: ✓ (?)
    • Status image toggle: active (doesn't make sense!)
    • Line edit: green, disabled (Solution is shown)
    • Counted as: wrong

Summary Page (after practice is finished)

  • DONE dani_l: One page only
  • DONE dani_l: Bar on top with colors that indicate how good the practice was
    • DONE dani_l: tooltips on the bar that indicate the meaning of the colors
    • DONE dani_l: caption under the bar
  • DONE dani_l: Table below (sorted, most mistakes on top)
  • 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 (or remove it)
  • 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

Word types

  • TODO: newly created sub word types should inherit their parent's grammar type -> Frederik?

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

Missing Artwork

  • TODO Icon for stop practice - idea: like start practice: flash cards with multimedia stop
  • TODO Icon/image for states:
    • User answered correct (✓)
    • User answered wrong (✗)
    • User has not answered yet (?)

TODO: screenshots that explain the above

Regressions in branch

  • Title is broken (documents show up with 0 as title, chainging root lesson behaves weird, it doesn't get saved)


(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?
