sysctlview https://www.freshports.org/deskutils/sysctlview/ is a GUI utility for sysctl on #FreeBSD.
It's probably my first #opensource project , it's still in the Ports Collection and runs fine, but it hasn't been updated in years.

Maybe it's finally time to brush up on #C++ and give sysctlview a proper rewrite.
The original version uses #gtkmm (#GTK for C++), but a few years ago I ran a poll and most people preferred #qt
So maybe a QTsysctlview is on the horizon?

Filmbook is now available on Flathub!

Your film tracking app just got easier to install! You can now get Filmbook directly from Flathub: https://flathub.org/apps/page.codeberg.bjawebos.Filmbook

Built with Rust & GTK4/libadwaita, Filmbook helps analog photographers keep track of their film usage with a smooth, modern interface that works great on desktop Linux and even Linux phones like the Librem 5 and Pinephone Pro!

Calling all analog photographers: I need your creative input! What features are you missing? What would make your film photography workflow even smoother? Your ideas will help shape the future of Filmbook.

Help #Linux peeps.. What are some clean #gtk easy to use software centers that are available in #nixos and integrate with #flatpak .

I'm currently using gnome-software in my nixbook project (that runs cinnamon desktop) and it's pissing me off with system level notifications I can't seem to silence.

I'd love to find another option

How can there even be an "free(): invalid pointer" error in #Python? I can only assume this is a bug in the CPython implementation… or perhaps in #GTK. Not sure if there's a way for me to tell, it happens very rarely but also randomly.
#coding

I'm looking for a standard way to develop GTK-based apps on #Linux but haven't figured it out yet. I found the Workbench app but don't understand how to use it.

I also tried prototyping an idea using #Python and the #GTK library with Claude, but still haven't found a solid approach to build the foundation.

Tomorrow I will give a presentation in #Helsinki about writing a native desktop app for #Linux with #Python and #GTK. I also heard that the event will be streamed.

I've been readying up my slides. I use free software, of course. #revealjs is a great #HTML based presentation framework. Diashows as code!

Do you want to learn how to write small desktop apps for yourself in #linux with #GTK? I'll tell you how.

I will give a presentation at #Helsinki Python Meetup next wednesday. Free entry. Please RSVP in this (unfortunately proprietary) service:

Calling all analog film photographers! I've been working on Filmbook, an open-source app to help you keep track of your film usage. It's built with Rust & GTK4/libadwaita for a smooth & modern experience – and it even runs on Linux phones like the Librem 5 and Pinephone Pro!

The first version is ready for testing, and I'd love your input on what features would make it even better!

Yesterday the "Reflection" project started officially as part of the new @PrototypeFund round!

The team consists of @p2panda and people from the GNOME gang around @tbernard and @jsparber.

We gonna release "Reflection" (formerly Aardvark) - a GTK-based, collaborative, local-first text editor! Aaaand:

All of this is part of a larger effort to explore p2p code, UX patterns, reusable UI components, debugging tools, organize events and document our learnings.

Can GTK feel like React or SwiftUI? Let’s explore modern takes on building Linux UIs.

Is a valid way to control the lifecycle of other threads in your program with a weak reference to a class? (which, when deleted, signals the other threads that they're out of scope and should end themselves)

Meddling with multithreading and #GTK.stack. Could probably do it with signals too, however using Python's "weakref" module seems to allow for more elegant program flow. Not sure about how quick the garbage collector works and if there would still be race conditions.

After 25 years of GObject, it’s time for a new direction.

Does anyone have a minimally functional example of how to integrate a panda3d window into a GTK4 window on Wayland? I only found one example from years ago with GTK3 on X11.

Linux Mint forks GNOME’s Libadwaita to add theme support

On numerous occasions, we've talked about the issue facing non-GNOME GTK desktops, like Xfce, MATE, and Cinnamon: the popularity of Libadwaita. With more and more application developers opting for GNOME's Libadwaita because of the desktop environment's popularity, many popular GTK applications now look like GNOME applications

Seems my (not so) small new feature PR for #Lutris will actually happen (well, at least the PR - let's hope they accept it). Works rather fine by now.
Should help make game installers more resilient having more than one file source. Also the revamped file handling should allow for easier addition of new file sources in the future.
Have to do some cleanup before submitting it though.

Would any #windows #developer want to work on a funky #Gtk C++ bug?

The Inkscape project is empty of windows developers and needs some help fixing a fairly serious issue: https://gitlab.com/inkscape/inkscape/-/issues/5219

If I had a windows machine, I'd have tried to fix this one. But I'm completely at sea for this type of issue without the OS on hand. (don't try developing on a VM or old computer, Inkscape is too big and slow to build on windows for that)

Is there some (even hacky) way to get this hover-over effect that turns the whole row background-color blue in #GTK 3 to be turned off *per row*? I know how I would set it for all menu items, however I'd like for it to be depending on whether or not an item is actually available. Right now I made it just "ignore" your selection (i.e. immediately snaps back to the last selected item if you select sth. unavailable), but I'd like to make it more obvious in UI.

I will be presenting remotely at GUADEC 2025 in Brescia, Italy!

I'll be talking about my journey with the Drum Machine app, how it became part of GNOME Circle, and how the GNOME community supports developers in bringing their ideas to life.
