Remove gtk_widget_set_app_paintable.

[Christian-Kr]

Hello to everyone,

as part of the migration to gtk4 remove the method gtk_widget_set_app_paintable. The gtk3 documentation says, that most widgets already ignore this setting and it is only helpful if you want to change the background of some widgets.

After testing the change, I can't see any widget background that might have changed. Maybe it has already been changed, or I just missed a change.

Please test the change and if everything is still working, accept the PR.

Thank you in advance. Greetings

@Christian-Kr : Just a note that we are in the process of releasing the 4.6 release. So your work will be reviewed a bit later.

Nice to see some work toward Gtk4, do you have a clear view of the amount of work needed? TIA.

Hello @TurboGit,

don't worry. I had a clear view for other applications, but for darktable, I just wanted to start coding. So no, I don't know the amount of work.

Greetings

Could we maybe have a new label we can use for Gtk4 preparatory work. Even better if we could have an issue to track some sort of to-do list, so others can assist with the work.

There will almost certainly be some more complicated bits of functionality to change so separate issues for those would be good as well (as-and-when you find that sort of thing).
