Greetings!

In the docs for tview, it is mentioned that:

When primitives are instantiated, they are initialized with colors taken from the global Styles variable. You may change this
variable to adapt the look and feel of the primitives to your preferred style.

Would it be possible to expand a bit on this and provide an explicit example of how this can be achieved, either for individual colors, or for entire themes?

Apologies in advance if this is something that is trivial to do -- I'm only on day two of working with Go (and quite impressed, so far!)

I did try updating / redefining Styles in the global package space, but it didn't seem to have any effect. I suspect I'm just misunderstanding how scoping works with global variables or something else very basic..

Any suggestions/guidance would be greatly appreciate though.

Thanks!

Never mind! I figured it out. Sure enough it was just a matter of using the proper namespacing syntax.

In case it helps anyone else, to modify a setting inside main(), you can do something along the lines of:

tview.Styles.PrimitiveBackgroundColor = tcell.ColorRed
