Subclassing QWidgets to save the widget state in a QSettings Instance. A setup method links the widget to key within the QSettings instance. The value is loaded during setup and gets stored when the widget state changes. Without calling this method, the widget has no special behaviour.

See the following snippet for a minimal example:

from PyQt5.QtCore import QSettings
from configwidgets import ConfigCheckBox

config = QSettings()
checkBox = ConfigCheckBox()
checkBox.setup(config, "checkBox")

install the package via pip:

pip install configwidgets
