What happened?

While trying to apply gtk-3 themes via adw-gtk3 I get the error:

Traceback (most recent call last):
  File "/app/lib/python3.11/site-packages/gradience/frontend/main.py", line 605, in apply_color_scheme
    PresetUtils().apply_preset("gtk3", self.preset)
  File "/app/lib/python3.11/site-packages/gradience/backend/theming/preset.py", line 120, in apply_preset
    self.set_gtk3_theme()
  File "/app/lib/python3.11/site-packages/gradience/backend/theming/preset.py", line 46, in set_gtk3_theme
    self.settings.set_string("gtk-theme", "adw-gtk3")
    ^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'FlatpakGSettings' object has no attribute 'set_string'

The FlatpakGSettings definition doesn't actually contain this function but does contain set: https://github.com/GradienceTeam/Gradience/blob/29fa687f2c8ffd68c61629716a42e7623f53683f/gradience/backend/utils/gsettings.py#L247

I'm also getting yapsy errors:

Traceback (most recent call last):
  File "/app/lib/python3.11/site-packages/yapsy/PluginManager.py", line 535, in loadPlugins
    is_correct_subclass = issubclass(element, self.categories_interfaces[category_name])
                          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: issubclass() arg 1 must be a class

which is probably causing the firefox theming to not work. This is what I get when I press the firefox toggle:

Traceback (most recent call last):
  File "/app/lib/python3.11/site-packages/gradience/frontend/widgets/plugin_row.py", line 95, in on_switch_toggled
    if self.switch.get_active():
       ^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'NoneType' object has no attribute 'get_active'

I am seeing the same error. (lots of them actually)

Platform:

Arch Linux, Gnome 45.3, Wayland, Gradience 0.8.0-beta2-8b5c6f5 (Flatpak)

[keilmillerjr]

Likewise. I have the same error on arch using gradience-git. It would be nice to have firefox matching. It's the most commonly used app on my desktop.

You just need to remove the _string from set_string in preset.py

[manan-gup]

Yeah, given what I've reported, I also thing the same. But, I'm not familiar with the project, so, I don't know if its 100% correct. Also, I can't get the project to build in the Gnome Builder flatpak, so, can't really experiment with it.

You can modify the existing file at /var/lib/flatpak/app/com.github.GradienceTeam.Gradience.Devel/current/active/files/lib/python3.11/site-packages/gradience/backend/theming/

You can modify the existing file at /var/lib/flatpak/app/com.github.GradienceTeam.Gradience.Devel/current/active/files/lib/python3.11/site-packages/gradience/backend/theming/

But this file doesn't have any lines matching "_string", I'll say more, no other file in this directory has anything like it
