    Ktimetracker


    What is KTimeTracker

    KTimeTracker tracks time spent on various tasks. It is useful for tracking billable hours and can report the hours logged by task and day. This time history can be exported to a comma-delimited text file for import into other billing and/or project management tools. KTimeTracker detects when your keyboard and mouse are idle and can associate different tasks with different desktops, two tools that can help keep the timer running on the correct task.

    Using KTimeTracker

    What KTimeTracker can do for you

    The current stable version of KTimeTracker (4.1) can:

    • organize and stopwatch tasks, subtasks

    KTimeTracker allows you to organize and stopwatch your work. You can put your daily todo-list into that tool. You can group your work by tasks, subtask and n-th level tasks, meaning that every subtask can still have a subtask below it, up to some 1000 levels.

    • edit task history and comments

    KTimeTracker allows you to edit your task's history and to put a comment for every event that you have stopped:

    Options

    KTimeTracker 4 has the following behavior options:

    Compatibility

    Up to KDE 3.1 (incl.), flat files were used to store the data. From KDE 3.2 on, the iCal format is used, but flat files can still be imported until KDE 4. With KDE 4, the custom fields X-KDE-karm-duration, X-KDE-karm-totalTaskTime, X-KDE-karm-totalSessionTime and X-KDE-karm-desktopList were renamed to X-KDE-KTimeTracker-duration and the respective other names. KTimeTracker 4 can still read karm iCal files, but not the other way round.

    Does it scale

    KTimeTracker scales well and it regularly tested with a 1.2 MB file (https://bugs.kde.org/attachment.cgi?id=14413&action=view) available from (https://bugs.kde.org/show_bug.cgi?id=110523). A ktimetracker benchmark is available from here.

    Developing KTimeTracker

    So you want to become a KTimeTracker developer

    Here are your classes:

    • mainwindow.*: Is the main window of the KDE application
    • karm_part.*: Is the KPart of KTimeTracker
      • timetrackerwidget.*: Is a widget with no or several tabs that contain
        • taskview.*: Is a treeListWidget that contains:
          • task.*: A QObject and QTreeWidgetItem. A task can be constructed from a taskview and a todo. As soon as you instanciate a task, it becomes visible in your TreeWidget.
          • karmstorage.*: Is the storage backend that contains a:
            • KCal::ResourceCalendar

    Nokia N810

    I got a Nokia N810 from Nokia to allow me porting KTimeTracker to it. I appreciate this a lot and am now kompiling KTimeTracker for arm. The project is not ready, here is what I found out:

    To kompile KTimeTracker for the Nokia N810

    • add the maemo repository
    • install openssh

    dbus

    dbus is clearly a developer topic. To test the dbus functionality of your KTimeTracker, have KTimeTracker running and proceed like in this example:

    qdbus
    ...
     org.kde.KTimeTracker
    ...
    qdbus org.kde.KTimeTracker
    ...
    /KTimeTracker
    ...
    qdbus org.kde.KTimeTracker /KTimeTracker
    ...
    method void org.kde.KTimeTracker.KTimeTracker.quit()
    ...
    qdbus org.kde.KTimeTracker /KTimeTracker org.kde.KTimeTracker.KTimeTracker.quit
    

    Internationalization

    You want to test the translation of KTimeTracker. For this, you want to call KTimeTracker in, say, german. For this, you need to know how you at all can call a KDE 4 program in another language than english. Here is as an example how I call akregator in german:

    wget http://websvn.kde.org/*checkout*/trunk/l10n-kde4/de/messages/kdepim /akregator.po  
    msgfmt -o akregator.mo akregator.po
    cp akregator.mo .kde4/share/locale/de/LC_MESSAGES/
    KDE4_LANG=de akregator
    

    The respective KTimeTracker translation is still stored in karm.*o, and it works.

    How to reproduce a stale lock

    Here is an example to give you an idea:

    touch .kde/share/apps/kabc/lock/_home_tom_.kde_share_apps_karm_karm.ics.lock
    

    How to get rid of debugging output

    cmake -DCMAKE_BUILD_TYPE=Release
    

    Goals

    • Unicode - I found out it is already capable of UTF-8.

    Where is what ?

    http://commitfilter.kde.org

    • You can get informed on irc about code changes at freenode,
    1. kde-commits
    • You can discuss about KDE pim development on freenode,
    1. kontact

    http://websvn.kde.org/trunk/KDE/kdepim/doc/ktimetracker

    • KTimeTracker all-you-need in the internet:

    http://userbase.kde.org/KTimeTracker

    • KTimeTracker as part of pim, for developers:

    http://pim.kde.org/components/karm.php / http://websvn.kde.org/trunk/www/areas/pim/components/karm.php

    • KTimeTracker as part of pim, for users:

    Development Direction

    The following similar programs can give you inspiration how to move forward developing:

    • hourglass
    • gnotime
    • titrax
    • taskCoach
    • Hamster

    Kontact plugin vs. Standalone

    The Kontact plugin is realized via a KPart. The elegant solution would be to have one KPart that can be integrated into Kontact and one shell that just displays the KPart. This is not so far now. At the moment, karm_part.cpp implements the KTimeTracker part and mainwindow.cpp implements the standalone application. Here's a patch that allows us to use the karm part (karm_part.cpp) as widget of mainwindow, not perfect yet, but showing a direction:

    IdleTimeDetector

    The idletimedetector is in the equally-named .cpp and .h file. It starts a qtimer and at every timeout, checks, if the X extension delivers for the last user interaction a timepoint that is further away than the maxIdleTime.

    About storage

    The storage of your KTimeTracker data takes place in an iCal file. That format needs a bit of explanation. A simple one looks like the following:
