"Have a GTK app with no tests? No problem!"
with Federico Mena Quintero at #GUADEC2025
25 July 14:20 CEST Brescia

Federico shows how to refactor messy GTK codebases so you can finally test them—without rewriting from scratch.

Tomorrow at 9 AM Brescia time I'm going to be talking (sadly, remotely) about GObject language bindings, and introducing my new C++ bindings for & GObject, peel

Folks, I can definitely recommend this talk from @bugaevc at #guadec2025!

https://floss.social/@gnome/114873444742029431

Sergey has been of great help for my minor stumblings of trying to write #ObjC #GTK bindings for #ObjFW. He's got formidable knowledge und deep insight into #GObject especially and Cxx languages in general.

One of the dumbest design decisions of #GTK is to have "warp scrolling" the default primary mouse button behavior.

Previously, if you middle-clicked the scrollbar, it would jump to that position within the buffer. Primary click moved up/down by page. GTK 3 reversed this for no reason.

There are some limited scenarios where jump scrolling is desired, but you should never break a standard UX convention without a tremendous benefit. There wasn't one.

The new modal dialogs in GTK/gnome that are nailed to the parent window's center and can't be moved are such unintelligent design. Libreoffice now uses these for the paragraph style editing dialog so now you can't move the dialog anymore to look at the effect of your settings on the actual document. A similar issue happens with the "save as" dialog in many GTK applications. Often you'd want to look at the content of the document to decide on a file name.

"Bridging type systems"
with Sergey Bugaev at #GUADEC2025
25 July 09:00 CEST Brescia

Sergey introduces peel, a fresh take on C++ bindings for GObject: zero overhead, full API coverage, deep type support.

Web sites are these days insanely bloated, sometimes youtube trows 1GB of RAM consumption per tab at me. GNOME Web is infamously known for consuming several gigs of RAM for almost nothing.

If GNU/Linux on phones is a serious issue, then i think the development of native apps (like GTK apps) for most of the web services that are out there is critical to make the experience bearable. Some of them are good but there's still a lot to be done.
