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.

With KDE 3.x, KTimeTracker was named KArm, with KDE 4.x, it is named KTimeTracker. For KDE 4.x, there is a stub called karm that just reminds you that the name has changed.

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<super>th</super>level tasks, meaning that every subtask can still have a subtask below it, up to some 1000 levels.

What ktimetracker will be able to do for you

The current development version of ktimetracker can:

• 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: {img src=http://pim.kde.org/img/screenshots/karm-edithistory.png width= height= align= desc= link= }

Options

KTimeTracker 4 has the following behavior options: {img src="img/wiki_up/KTimeTrackerConFigure.png" }

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). We have never observed slow-downs caused by the size of the calendar-file.

Developing ktimetracker

• look at bugs.kde.org
• join our discussion on irc.kde.org, channel #kontact
• learn programming with KDE's Programming Tutorial

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

dbus

dbus is clearly a developer topic. To test the dbus functionality of your ktimetracker, have ktimetracker running and proceed like this: {CODE()} 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 {CODE}

Info for 4.0

See http://www.nabble.com/Re:--Kde-cvs-announce--KDE-4.0-Release-Branch-td14615393.html

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: {CODE()} 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 {CODE} The respective ktimetracker translation is still stored in karm.*o, and it works.

How to reproduce a stale lock

{CODE()} touch .kde/share/apps/kabc/lock/_home_tom_.kde_share_apps_karm_karm.ics.lock {CODE}

How to get rid of debugging output

{CODE()} cmake -DCMAKE_BUILD_TYPE=Release {CODE}

Goals

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

Development Direction

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

• hourglass
• gnotime
• titrax
• taskCoach

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:
