You may have read about my new-found fondness for Plasma’s Clock app. Following the development of a “Picture in Picture” protocol for Wayland, I remembered how I once saw someone put up a little timer window during a lunch break while screen-sharing a presentation. I figured, I wanted that, too!
KIO (KDE Input/Output) is what allows KDE applications to transparently and asynchronously access files, both local and over the network. It also provides many of the user interfaces for manipulating files, such as the Places panel, Open/Save dialog, folder properties, new file menu, and many more. The other day I went through some of its dialogs and gave them a slight overhaul.
Back in ye olde days there was a running gag that Plasma was all about clocks. With its then-new widget system you could add as many as you wanted, after all. Plasma included not only an analog and a digital clock, there was a binary clock, too, and my all-time favorite fuzzy clock that shows the current time in a colloquial textual way, such as “Quarter to seven”.
For Plasma Mobile, however, we needed not only a simple clock display but also an alarm clock that could schedule proper system wake ups. Additionally, for travelers a world clock would be nice, and why not have a simple timer and stopwatch as well. That’s KClock, a sexy little Kirigami-based clock app.

The M is silent. In computing this stands for the underlined letters in menus that can be triggered using an Alt+Letter key combination, one that you can remember and apply later to navigate around more quickly.
Qt and other toolkits typically use an ampersand to denote a mnemonic when assigning a menu entry. For instance, “&Shutdown” will be displayed as “Shutdown” and trigger on Alt+S whereas “Slee&p” will be “Sleep” and trigger on Alt+P. Of course this isn’t limited to menus, pretty much any control, buttons and what not, can have mnemonics. Since they are part of the label, a translated string can and likely will have a different one.

The year has brought many major changes, both to KDE and to me personally: We did the KDE MegaRelease 6, the next major update to KDE’s software suite. Plasma 6 further made Wayland the default graphical session. I also spent a lot more time in Qt itself, particularly Qt Wayland, rather than KDE code. Anyhow, between family visits and feasts there’s always some time for quality KDE hacking.

There’s features that you know are really important to some of our users but you frankly don’t really care for them much yourself. Printing is one such example. Recently, I actually had to print lots of paperwork, so I had a reason to fix some of my more pressing issues with our Print Manager.
The biggest regression from the Plasma 4 days, when we moved from individual System Tray popups to a unified square view, was that Print Manager had to give up its two pane layout that showed the print queue directly in the popup. In order to view and cancel print jobs, you now had to select the printer and open its print queue window, and close it again after you’re done.
Continue reading Hardware ShenanigansWhile I do have a Qt git build on my machine that I use for development, I usually only test individual applications and functionality but hardly ever run my full Plasma session on it. This means that for day-to-day use I typically only get to enjoy new Qt features once they have actually been released.
I’m pleased to announce the immediate availability of Plasma Browser Integration version 2.0 on the Chrome Web Store and Microsoft Edge Add-ons page. This release updates the extension to Manifest Version 3 which will be required by Chrome soon. The major version bump reflects the amount of work it has taken to achieve this port.
Plasma Browser Integration bridges the gap between your browser and the Plasma desktop. It lets you share links, find browser tabs and visited websites in KRunner, monitor download progress in the notification center, and control music and video playback anytime from within Plasma, or even from your phone using KDE Connect!
Continue reading Plasma Browser Integration 2.0Next week Akademy, KDE’s annual community conference, will take place in Würzburg, Germany. There are a few features that I actually began during various conferences throughout the years to address real-world problems. I decided to have look at some of them again that would be most useful for people travelling to Akademy from abroad or who will be giving a presentation there.
