I didn't know if this fell under share code or questions, as this isn't a question about Python or Pythonista per se.

I know this is a simple equation. I remember doing something like this in highschool. For the life of me I can't think of the solution or how to search for the solution. Essentially I am changing the .background_color of a tableview via scrollview_did_scroll. I want to move from 1.0 to a target value as the scrollview.content_offset[1] increases, when the offset hits 70 I will change to another action. The target value being the respective values in myrgb.

This is a snippet of example code. I know we hate snippets, but the entire project looks rather gross as its still a scratchpad draft.

def scrollview_did_scroll(self, scrollview):
    x, y = scrollview.content_offset
    myrgb = (26.0/256, 188.0/256, 156.0/256)
    r = 
    g = 
    b = 
    #At y's origin, r, g, b will be (1.0, 1.0, 1.0)
    scrollview.background_color = (r, g, b)
    

Fantastic explanation. Always above and beyond, thank you omz! I was not that far off. With the exception of the from_color, I was missing the + p from what I conjured up before heading to the forums. I had multiplied to_color and the value of (1.0 - p). I also appreciate the use of min and max as I would have had to debug that when I would've caught it when reaching the end of the scrollview height.

When the input comes up Pythonista hangs. The decorator is in place (I assume correctly). Any help is much appreciated! >> Gist Link <<

It's probably a user error but when the code is ran, the images aren't loaded until the cells are scrolled out of view. Any help appreciated!

I bought myself a thermodo for entertainment and because they have an sdk.

The feature request would be too add the ability to 'listen' to mic data.

I didn't see anything in the documentation. I have a NavigationView with a TableView. If I push a new TableView, how can I tell when the view on screen changes? More clarification: I have a custom refresh button that disappears when I push a new view, how do I bring it back when the user returns to the initial view in the NavigationView hierarchy?

So I see!! Awesome. Thank you.

I can alter border widths and colors of the cells I create. How can I access those properties on the autogen cells that fill out the rest of the tableview?

Very cool. I will look into implementing this a little later today. Thank you for your help!

@JonB I considered that but if feels like a cheap fix. I might end up creating blank cells if this isn't something that isn't planned for any soon to be releases.
