Official account of the GTK project.

GTK is a general purpose graphical toolkit for a wide variety of environments, from desktop to mobile platforms. You can use GTK to build beautiful applications on Linux, as well as Windows and macOS, using one of the many programming languages that support it.

Reminder: instead of using StackOverflow for your questions about GTK and the GNOME software stack, use the GNOME Discourse instance:

https://discourse.gnome.org

You can also use it for applications and the overall GNOME desktop.

Eyedropper lets you pick a color from your screen, and see it in various formats without any extra fuss. When you want to extract a color from your display, just click on the relevant pixel and find it's exact shade. The app holds a list of your previously picked colors, and even lets you see a selection of palettes generated from the one currently selected!

You can follow the app's creator here: @FineFindus

You can get the app on Flathub here: https://flathub.org/apps/com.github.finefindus.eyedropper

@lazarus @gnomeapps @FineFindus the color chooser has a "pick" functionality already; doesn't mean there can't be applications that refine/improve that functionality for specific use cases. A toolkit has to serve every user; an application has an intended audience.

What GTK app are you working on?

@GTK@floss.social avatar

@chfkch It's still GTK, even when using languages other than C, as well as libraries that augment the API or UI elements 😎

@GTK@floss.social avatar

Thanks for all the replies! It's great to see so many different types of applications made with GTK.

Keep 'em coming, and make sure to add a link to Flathub and/or a screenshot of your application 😉

fkinoshita, to GNOME

It just needs an icon but otherwise it's pretty much ready for flathub!

A screenshot of this WIP libadwaita application, it has two modes, a mode for hiragana and another one for katakana, on both modes you are presented with a big text on top that is the romanized version of some hiragana/katanaka character and you have to guess which character corresponds to that romanized text.

@fkinoshita Next step: kanji 😉

I wonder why reactive GTK hasn't taken off yet. Specially in the context of GNOME.

There have been several projects. Relm4 looks well maintained but doesn't appear to be used much.

Thoughts?

Also 🧵

GTK,
@GTK@floss.social avatar

@user8e8f87c @sonny if support from big companies is an indication of whether a project is dying or not, then GTK has been dying for the past 25 years, considering that very few companies have ever supported it from the start.

GTK's strength comes from the contributions of many individuals, and from its strong copyleft licensing.

GTK,
@GTK@floss.social avatar

@user8e8f87c @sonny @ubuntu companies could pay for GTK developers; or they could fund platform developers through the GNOME Foundation. Just like funding for a lot of infrastructure projects, it's hard to justify as a business decision, because it benefits everyone, including competitors. Plus, the desktop is not seen as "cool" any more; the accessibility investment, for instance, came in the early 2000s, and it's considered "done", instead of being a constant work in progress.

Hello Mastodon World!

I am please to announce a new version of Cambalache in my first post, toot?

> Can apps written with GTK be run on windows?

Sure: https://www.gtk.org/docs/installations/windows/

> How much cross-platform are they?

GTK is a portable toolkit; the general expectation is that you use it to write Linux apps and they will also run on Windows and macOS.

What else?

@gregorni It's just GTK, according to the trademark application 😉

There are generally two categories of performance tuning, in my experience.

  1. I can make that faster
  2. I can make it not have to do that at all

@hergertme everyone concentrates on 1 because who doesn't like a good puzzle? Very few focus on 2

A new stable release is out! Lots of changes for 4.12:

  • list views can have sections
  • accessibility improvements
  • multiple fixes for the Vulkan renderer
  • better support for GLES2 in the GL renderer
  • fixes for Windows and macOS
  • new support for various texture formats

and tons of bug fixes.

If you have experience maintaining a GitLab CI runner on macOS, and you wish to contribute to building and testing GLib and GTK on macOS, please join the GNOME Infrastructure channel to help maintaining the macOS server provided by the GNOME Foundation, otherwise we will have to retire it. More details on Discourse: https://discourse.gnome.org/t/potential-retirement-of-the-macos-ci-builder-for-glib-and-gtk/16198

GTK,
@GTK@floss.social avatar

To further clarify, since it seems that there is some confusion about it: this call for help is for maintaining the existing Mac CI runner used by GLib and GTK to build those projects on macOS in their respective CI pipelines.

Any offer of helping with macOS-specific code and builds are, of course, appreciated, but are independent of the topic at hand.
