once i wrote a nice little library called #libgtkflow, a flow graph library for #gtk . i have never seen a project done with the library as cool as this: https://rasterflow.io/ it's a tool for #image #manipulation with #gegl. and i just love how the website documents all the available filters!

Both #Helvum and #libgtkflow implement Flowgraphs with GTK.
Neither of them are usable for my App. Thus I probably need to implement a third Flowgraph library in #Golang, which again - will not be usable by anyone else.

I merged a huge PR from activey into #libgtkflow , my #gtk flow graph library. He made significant contributions to the codebase. Amongst many other things he made title widgets possible which i appreciate greatly. He also showed me two projects he's doing with libgtkflow and have to say that his attempt at a GEGL-filter chain program is already better than mine was ( https://notabug.org/grindhold/effector ).

Here's a screenshot of the demo now containing title widgets :)

#libgtkflow can now render dock widgets in its #gtk 4 variant. you can add arbitrary widgets to your docks instead of just a label with the dock's name on it!

check it out at https://notabug.org/grindhold/libgtkflow or https://codeberg.org/grindhold/libgtkflow

should we render the delete button with or without frame? :) see first reply for example screenshot

#libgtkflow #gtk

with frame

10%

without frame

90%

these nodes have reached critical levels of fanciness! style your #libgtkflow nodes with CSS. and i improved the rendering of the corners. they arent faking to be round anymore!

i just realized that #libgtkflow 4 has just about a third (38%) of the codebase of #libgtkflow 3 . many kudos to all the #gtk developers out there for making this possible by simplifying the #gtk API so much.

🥳 Celebrate with me for two reasons! The rewrite is done. i have released #libgtkflow for #gtk 4 in version 0.2.1 . check it out at https://notabug.org/grindhold/libgtkflow / https://codeberg.org/grindhold/libgtkflow

IMPORTANT: libgtkflow is now called libgtkflow3 and is complemented by libgtkflow4 !

Second reason: I have decided to bump libgtkflow3 and libgflow to 1.0 ! The API has been stable enough for a long time and maybe this encourages developers more to use the library.

oh wow. look at those chonkers! the five last known bugs, including resizing behaviour of the nodes, have been fixed. now i have to adapt some things downstream and intend to do a release tomorrow!

spoiler: of course, libgtkflow4 is going to be published under LGPLv3 as all other libs that derive from the repo https://notabug.org/grindhold/libgtkflow / https://codeberg.org/grindhold/libgtkflow
