Subject: [PATCH 6/7] Fix setting CSS with latest GTK4
|
|
|
|
In the upcoming 4.10 release, the type annotation was fixed [1]. There
|
|
may be some overrides added in PyGObject [2] to avoid this difference,
|
|
but we don't depend on a specific version of it to be able to rely on
|
|
that (and it's not released yet.) This code should work with the
|
|
override as well.
