RE: mastodon.social/@ebassi/115429…

Got nerdsniped around lunchtime yesterday, and ended up implementing a shared "reduced motion" setting for GNOME and the rest of the xdg stack:

- gitlab.gnome.org/GNOME/gtk/-/m…
- gitlab.gnome.org/GNOME/gsettin…
- github.com/flatpak/xdg-desktop…
- gitlab.gnome.org/GNOME/xdg-des…
- gitlab.gnome.org/GNOME/gnome-c…

Add a "reduced motion" preference to the settings portal · flatpak xdg-desktop-portal · Discussion #1839

Under GNOME we're currently abusing the boolean "enable animations" toggle, but this poorly maps to the actual accessibility issue of reduced motion. Ideally, we want to map to the same kind of set...

For the next GTK cycle, Matthias has been working on a format for symbolic icons that can be rendered efficiently by GTK, including animations; it is based on a subset of SVG with custom vendor attributes:

Happy Disability Pride Month everybody :)

During the past few weeks, there's been an overwhelming amount of progress with accessibility on GNOME Calendar:

• Event widgets/popovers will convey to screen readers that they are toggle buttons. They will also convey of their states (whether they're pressed or not) and that they have a popover.

• Calendar rows will convey to screen readers that they are check boxes, along with their states (whether they're checked or not). Additionally, they will no longer require a second press of a tab to get to the next row; one tab will be sufficient.

• Month and year spin buttons are now capable of being interacted with using arrow up/down buttons. They will also convey to screen readers that they are spin buttons, along with their properties (current, minimum, and maximum values). The month spin button will also wrap, where going back a month from January will jump to December, and going to the next month from December will jump to January.

• Events in the agenda view will convey to screen readers of their respective titles and descriptions.

Accessibility on Calendar has progressed to the point where I believe it's safe to say that, as of GNOME 49, Calendar will be usable exclusively with a keyboard, without significant usability friction!

There's still a lot of work to be done in regards to screen readers, for example conveying time appropriately and event descriptions. But really, just 6 months ago, we went from having absolutely no idea where to even begin with accessibility in Calendar — which has been an ongoing issue for literally a decade — to having something workable exclusively with a keyboard and screen reader! :3

Huge thanks to @nekohayo for coordinating the accessibility initiative, especially with keeping the accessibility meta issue updated; Georges Stavracas for single-handedly maintaining GNOME Calendar and reviewing all my merge requests; and @tyrylu for sharing feedback in regards to usability.

All my work so far has been unpaid and voluntary; hundreds of hours were put into developing and testing all the accessibility-related merge requests. I would really appreciate if you could spare a little bit of money to support my work, thank you 🩷

Matthias posted an update on the current state of Accessibility in GTK and GNOME on the development blog: blog.gtk.org/2025/05/12/an-acc…

#gtk #gnome #accessibility #a11y

As part of our volunteer-driven accessibility initiative in GNOME Calendar, and for the first time in the 10+ years of Calendar's existence, we finally completed and merged the first step needed to have a working calendar app for people who rely on keyboard navigation. This merge request in particular makes the event widgets focusable with navigation keys (arrow left/up/right/down) and activatable with space/enter. This will be available in GNOME 49.

Most of GNOME Calendar's layout and widgets consist of custom widgets and complex calculations, both independently and according to other factors (window size, height and width of each cell, number of events, positioning, etc.), so these widgets need to be minimal to have as little overhead as possible. This means that these widgets also need to have the necessary accessibility features reimplemented or even rethought, including and starting with the event widgets.

We also hope to get other parts of GNOME Calendar accessible before GNOME 49, but I can't promise anything at the moment. We did start working with making the month view accessible: gitlab.gnome.org/GNOME/gnome-c…

Besides the AMD crasher, I wondered why the dev version of Showtime, #GNOME's power-efficient video player in incubation, sometimes still refused to launch; turns out it's randomly crashing with a segfault on startup for another reason.

After jumping through hoops to get a backtrace (#Python in #Flatpak makes things somewhat harder to debug), it turns out that #GStreamer is not the culprit. Presumably, it may be a bug in #GTK or somewhere else in the stack. Details here: gitlab.gnome.org/GNOME/Incubat…

The 2025 GTK hackfest has started in earnest, here in Brussels

#gtk #GNOME #hackfest

Introducing Refine, an app to tweak advanced and experimental settings in GNOME. It is an alternative to GNOME Tweaks, and is a pet project I'm currently working to experiment with PyGObject and dconf, while following the data-driven, object-oriented, and composition paradigms.

The entire codebase is made up of widgets that provide all the functionality needed to add an option. For example, instead of adding each option programmatically in Refine, the ultimate goal is to have it all done in the UI file.

For example, if we want to add an option to enable or disable middle click paste, all we need is the following code in the UI file:

$RefineSwitchRow {<br>  title: _('Middle Click Paste');<br>  schema-id: 'org.gnome.desktop.interface';<br>  key: 'gtk-enable-primary-paste';<br>}<br>

You can get Refine on Flathub: flathub.org/apps/page.tesk.Ref…

A simple Wayland compositor widget for Gtk 4 which can be used to embed other processes windows in your Gtk 4 application.
It was originally created for Cambalache's workspace using wlroots, a modular library to create Wayland compositors.
Following Wayland tradition, this library is named after my hometown in Santa Fe, Argentina
