I'm using kivy to create a small App for computer aided learning.
At the moment I have some problems with accessing config values">values. I get the value with
self.language = self.config.get('basicsettings', 'language')
in the main App-Class. That works fine, however, I don't know how to access these value inside another widget - in this case the AudioButton.
I'm using a ScreenManager, which contains a Screen. Inside is a BoxLayout, which contains a GridLayout and this holds several AudioButtons.
Now, in this AudioButton I want to know the current value of self.language defined in the mainApp.
self.language
In .kv files I can do something like
`text: app.language`
to get it, but how to do it directly in Python?
If I use a dummy label in kv to get the value, it works, but when I change the setting, I need to restart the App, because I don't know what I need to add to on_config_change() to update the value during runtime.
on_config_change()
Here's a very simplified version of my App with all interesting parts, I hope.
class AudioButton(Button): filename = StringProperty(None) sound = ObjectProperty(None, allownone=True) def on_press(self): if self.ids.playsound.text == '1': self.sound.play() else: print('NoSound') class MainScreen(Screen): pass class Pictures1(GridLayout): def __init__(self, **kwargs): super(Pictures1, self).__init__(**kwargs) self.cols = 2 btn = AudioButton() self.add_widget(btn) btn = AudioButton() self.add_widget(btn) class Lesson1(Screen): pass class ScreenManagement(ScreenManager): pass class LunahutsoApp(App): def build(self): self.settings_cls = SettingsWithSidebar self.use_kivy_settings = False self.language = self.config.get('basicsettings', 'language') self.playsound = self.config.get('basicsettings', 'playsound') return ScreenManagement() def build_config(self, config): config.setdefaults('basicsettings', { 'language': 'austrian', 'playsound': 1}) def build_settings(self, settings): settings.add_json_panel('Lunahutso', self.
