Kalendar v0.2.0 is out now, adding drag-and-drop, improved calendar management, and lots of bug-fixes — Kalendar devlog 22

A week has passed since our first release and we are back with another one! We’ve worked hard to go through your bug reports and suggestions, and thanks to these we have a new version of Kalendar that is more stable and powerful than ever.

Note: Kalendar is still under heavy development. You’re free to poke around and try it out, but it is not yet final software! If you want to contribute to its development, join us in Kalendar’s Matrix room.

Our 0.2.0 release

While we are excited to have you try Kalendar, please not that 0.2.0 is still an in-development release and that there will be bugs and missing features. We want your feedback — especially bug reports! These will help us improve Kalendar as much as possible before releasing 1.0.

It is now in the hands of distribution packagers to add Kalendar to their repositories. The most up-to-date and unstable version of Kalendar will continue to come from our git repository, and some users have gone ahead and started packaging builds of Kalendar coming straight from our master branch.

We hope you enjoy using Kalendar as much as we enjoy making it, and look forward to what you have to tell us about it!

Now, here’s what’s new this week:

Drag-and-drop incidences to change their times

!147: Add drag and drop to change incidence start times (Claudio Cambra)
Commit 95b2a5f5: Dragged incidences now correctly return to where they were when dragged into non-droparea space (Claudio Cambra)

Another highly-requested feature has been added to Kalendar: you can now drag-and drop editable incidences in your views to change their times.

This feature has been added to all the calendar views. Both the month and schedule views let you drag and drop incidences onto different days and thus change the start date of your dragged incidence, while the week view offers more granularity by letting you set your incidence start time to the nearest quarter-hour.

Manage and customise your synchronised calendars

!148: Add menu with calendar editing options (Claudio Cambra)

We have also added a new context menu that you can invoke by right-clicking on your synchronised calendars in the sidebar. This context menu provides a number of new actions that let you easily manage your calendars straight from Kalendar.

  • ‘Edit calendar…’ invokes a properties dialog that lets you set an icon, name, and retrieval (sync) settings for this calendar
  • ‘Update calendar’ lets you immediately refresh the calendar and pull new changes from the calendar source
  • ‘Delete calendar’ is… self-explanatory
  • ‘Set calendar colour…’ lets you change the calendar’s colour without having to go into the settings

Usability tweaks and visual improvements

Commit 2a7db762: Can now press enter when delete dialog open to quickly delete (Claudio Cambra)
Commit ab0b5bd9: Completed tasks now have strikeout across views (Claudio Cambra)
Commit d06eed8f: Add number of tasks left to complete to filter header (Claudio Cambra)
Commit 53b7cfdd: Completion sliders now have highlight colour of parent collection (Claudio Cambra)

We’ve made some things faster and clearer.

Incidence deletion, for instance, now responds to the Escape and Return/Enter keys. So if you bring up the dialog to delete an incidence, you can rapidly dismiss it by either pressing Escape or quickly delete by pressing enter.

Regarding tasks: these are now more clearly marked as completed throughout calendar by appearing with strikethrough text across Kalendar’s calendar views.

In what is potentially an anxiety-inducing addition, we have also added the number of tasks to be completed to the tasks view’s header. This should let you know how much stuff you have left to do, which should help you panic a bit more!

Lastly, we have tweaked the completion sliders in tasks to have the same colour as the task’s parent calendar, helping the incidence info section feel less incongruent colour-wise.

Kalendar is out! — Kalendar devlog 21

That’s right! Kalendar is now on version 0.1, and we have a first release. There’s still a lot we have left to work on before we get to 1.0, but we are getting there! More on this below.

We also have a truly titanic changelog for the past two weeks. Some truly big changes and a load of smaller ones make Kalendar better than ever and should mean a beta that is a significant improvement upon our previously unstable builds.

Note: Kalendar is still under heavy development. You’re free to poke around and try it out, but it is not yet final software! If you want to contribute to its development, join us in Kalendar’s Matrix room.

Our initial release

Kalendar now has a 0.1 release that you will (hopefully!) soon be able to install on your system. Note that this is still an in-development release and that there will be bugs, features still to be added, and so on. We want your feedback — especially bug reports! These will help us improve Kalendar as much as we possible can before we can release a truly stable 1.0 version.

You can get the tarball for Kalendar version 0.1 here.

It is now in the hands of distribution packagers to add Kalendar to their repositories. The most up-to-date and unstable version of Kalendar will continue to come from our git repository, and some users have gone ahead and started packaging builds of Kalendar coming straight from our master branch.

We hope you enjoy using Kalendar as much as we enjoyed making it, and look forward to what you have to tell us about it!

Now, here’s what’s new this week:

Massive performance gains

!140: Overhaul model assignment in views and centrally manage models (Claudio Cambra)

A massive refactoring of how incidences are retrieved means that Kalendar is now significantly faster to load, change views, and change dates than it was before. Those of you wanting to use Kalendar on older devices or the PinePhone will really appreciate this change, and using the app should now feel substantially faster and smoother!

You can now import iCal (.ics) files into Kalendar

!144: Add .ics import feature (Claudio Cambra)

A hotly requested feature is now a part of Kalendar: iCal importing!

You can now import .ics files and are presented with a choice of what to do: you can either create a new calendar from this file, or merge the file’s incidences into one of your existing calendars. This should make it a lot easier to get your data out of proprietary services and into your local machine, where your data is safe and sound.

Don’t worry, though: you can still use your preferred online services. 😉

Animations make things more swishy and swooshy and smoooooth

!142: Animate more elements of the UI (Claudio Cambra)

Selecting incidences now makes their colours shift in and out smoothly, with a nice colour-change animation that should make Kalendar feel much slicker.

We’ve given headers a similar treatment: resetting the all and multi day header in the week view now makes it slide up instead of simply be up, and the filter header now smoothly slides in and out of the current view too.

Improving the sidebar

!143: Sidebar improvements (Claudio Cambra)

Spot the search bar in the top left, the new tags in the sidebar, and the collapse ‘Calendars’ section

The sidebar now lets you collapse the ‘Tags’ and the ‘Calendars’ sections, letting you hide the sections that you don’t use. We’ve also changed the tags section to now show you actual tags instead of just a list of labels, making it look prettier, be clearer, and take up less vertical space.

Lastly we’ve removed the search bar from the tasks view header and moved it into the sidebar. This gives us more room to play withy in the future, and soon we will be extending the use of this sidebar searchbar into the rest of Kalendar.

The tasks view is faster and prettier than ever

Commit bd32795b: Added reset button to tasks view collection title to easily reset filtering collection (Claudio Cambra)
Commit bbdbe71b: Tasks tree view decoration now highlighted with task color on hover (Claudio Cambra)
Commit a58ff22b: Highlighted task now has less strong color, making checkbox and text visible, and now color pulled from task color (Claudio Cambra)

One usability improvement that came about as a suggestion from a tester is now here: resetting the current task calendar is much more obvious as we’ve added a ‘reset’ button in the header.

Subtle!

We’ve also added a few cool aesthetic tweaks: the expandability marker and the task highlight now both use the colour of the task, which we think looks pretty nice.

Making things clearer in the week view

Commit 5de8c257: Slightly thickened current hour label in week view (Claudio Cambra)
Commit 79f8de00: Made current time markers in weekview more accurate, overlapping hour labels now become invisible (Claudio Cambra)
Commit edd52764: Fixed breakage of hour label overlap calculations on current time change (Claudio Cambra)
Commit 5bcf09c8: Week view current week now scrolls to current time on load (Claudio Cambra)
Commit 131a5394: Week view now consistently scrolls to correct position (Claudio Cambra)

The week view now has a current time label in the hour label column to the left, making it much clearer where exactly the current time marker is pointing to. This hour label remains visible throughout the day, and hides the hour labels it overlaps with.

Additionally, the week view now automatically makes sure to scroll near the current time, meaning you won’t have to scroll down to the current time when you want to check your events.

The incidence editor is faster and a lot more stable

!141: Move all date-handling stuff to C++ (Claudio Cambra)
Commit 660e7330: Simplified timepicker and streamlines date assignment, should fix related bugs (Claudio Cambra)
Commit 7e805ddb: Pressing enter in the incidence editor now adds/edits current incidence (Claudio Cambra)
Commit 56c8c88e: Made time picker be exact size needed + aligned to right of time combo (Claudio Cambra)

Date and time handling in the incidence editor has been completely rewritten from scratch. Why? Because JavaScript dates can be pretty unpredictable, especially in the context of variables such as timezones, daylight savings time changes, and so on. Qt’s QDateTime, QDate, and QTime classes offer much more explicit, predictable, and controllable handling of all of these things, so we have replaced QML/JS dates across Kalendar with these instead. The result is the elimination of all date and time related bugs in the incidence editor.

We’ve also made some tweaks for the sake of usability. For example, something I personally found annoying was that you couldn’t just slam enter whenever you were done editing an incidence and have that save your changes. Well, now you can, so slam that key away.

The time picker’s size and position has also been tweaked to ensure that it is always within window bounds and takes up only as much space as it needs to.

Speaking of time: the time fields in the editor now show the set time in the same way as the rest of your system (e.g. 24 hour time or AM/PM), and you can now type in the time in the same way too.
