How to give a Button item a RGBA Color?

[kami83]

Hi,

i would like to change the color from a Button item like this:

v[sender.name].background_color = "RGBA(1.000000,0.400000,0.400000,1.000000)"
But this is not working. The color is always white after this. So how to give a RGBA value?

Thx a lot.

On the Pythonista console:

• https://omz-software.com/pythonista/docs-3.4/py3/ios/pythonista.html#pythonista-interactive-prompt

>>> from ui import Button
>>> button = Button()
>>> button.background_color
(0.0, 0.0, 0.0, 0.0)
>>> button.background_color = (1.000000, 0.400000, 0.400000, 1.000000)
>>> button.background_color
(1.0, 0.4, 0.4, 1.0)

The ALPHA value might take a bit of getting used to, so play with alpha being 00, 0.5, and 1.0.

Also hex ("#FF0000") and CSS colors... https://omz-software.com/pythonista/docs/ios/scene.html#colors

>>> button.background_color = "magenta"
>>> button.background_color
(1.0, 0.0, 1.0, 1.0)
>>> button.background_color = "midnightblue"
>>> button.background_color
(0.098039, 0.098039, 0439216, 1.0)
