HISTORY

After our CircuitPython meeting on 2021-03-15. It was decided to use the library colorsys as a helper to add style for different widgets. old PR #139 will be closed and changes will be followed in this. This new PR uses the new unpackaged library. For completion I added the same text as previous PR. I include also a new example of usage

Features

The change will add the feature to use label with styles. With this feature you could possible create the same style among differents widgets. The syles are taken from the PySimpleGui Project

Changes

There are changes in the following files:

__init__: Add setter and getter to add style functionality
label.py: new parameter label_style added

Tests

Expected result of the example is:

Others

See https://github.com/adafruit/Adafruit_CircuitPython_CPython/issues/13 for projects updates. Code example, style file and helper functions will be added there
