将 kivy 设置重置为原始值
Reset kivy settings to original values
我正在构建一个应用程序，想知道如何将 kivy 设置重置为其默认值。另外，是否可以添加一个将设置重置为默认值的按钮。这是我的代码：
from kivy.app import App
from kivy.lang import Builder
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.settings import SettingsWithSidebar
from plyer.facades.storagepath import StoragePath
import plyer, json
settings_json = json.dumps([
{'type': 'title',
'title': 'example title'},
{'type': 'bool',
'title': 'A boolean setting',
'desc': 'Boolean description text',
'section': 'example',
'key': 'boolexample'},
{'type': 'numeric',
'title': 'A numeric setting',
'desc': 'Numeric description text',
'section': 'example',
'key': 'numericexample'},
{'type': 'options',
'title': 'An options setting',
'desc': 'Options description text',
'section': 'example',
'key': 'optionsexample',
'options': ['option1', 'option2', 'option3']},
{'type': 'string',
'title': 'A string setting',
'desc': 'String description text',
'section': 'example',
'key': 'stringexample'},
{'type': 'path',
'title': 'Download Folder Path',
'desc': "All downloaded manga will be found in this folder called 'manga_downloader_root' ",
'section': 'example',
'key': 'pathexample'}])
Builder.load_string('''
<Interface>:
orientation: 'vertical'
Button:
text: 'open the settings!'
font_size: 150
on_release: app.open_settings()
on_press: app.destroy_settings()
''')
class Interface(BoxLayout):
pass
class SettingsApp(App):
def build(self):
self.settings_cls = SettingsWithSidebar
self.use_kivy_settings = False
setting = self.config.get('example', 'pathexample')
print(setting)
print(plyer.storagepath.get_downloads_dir())
return Interface()
def build_config(self, config):
user_downloads_dir = plyer.storagepath.get_downloads_dir()
config.setdefaults('example', {
'boolexample': True,
'numericexample': 10,
'optionsexample': 'option2',
'stringexample': 'some_string',
'pathexample': user_downloads_dir })
def build_settings(self, settings):
settings.add_json_panel('Panel Name', self.config, data=settings_json)
def on_config_change(self, config, section, key, value):
print (config, section, key, value)
if __name__ == "__main__":
SettingsApp().run()
有关更多上下文，我希望使此应用程序在 android 和 PC 上都能运行。是否也可以将此代码合并到可以通过图标打开的导航栏中。
所以我不久前就想通了，我会 post 为任何发现此问题的人提供一个最低限度的答案。我的解决方案使用此 Github post .
