St.BoxLayout child meta deprecated in Gnome 3.38

[sebrem]

Hi,

I can't get the extension to run, I can configure it but noting happens. On further debugging I get meta is null in "gnome looking glass" - which leads to https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/3264 - and indeed I'm using gnome 3.38 (Debian unstable). Probably the code needs to be updated, unfortunately I'm new to GTK extensions.

Does anyone have a hint how to patch this?

Thanks

Sebastian

Hi, I was trying to debug this for another extension and saw the open question.

It appears that the root cause is the custom child meta functionality in StBoxLayout that was deprecated in Gnome 3.36 and removed in Gnome 3.38.

Here are some examples of extensions which have issued patches:

• hslbck/gnome-shell-extension-radio@9ade1d9
• arelange/gnome-shell-extension-hibernate-status@acbacd5

and a related fix for a prior deprecation:

• https://gitlab.com/jenslody/gnome-shell-extension-openweather/-/commit/281d31643a76f912d4801095a4822e7255fb258c

This Stack Exchange question should help to identify the affected lines of code.

To learn more about the functionality that was removed, read through these commits:

Good luck!
