Add a method to update item's color

[vsukhoml]

add_text() allows to set color of the text, set_value() can update text, but there is no way to update a color of the text.

For add_selectable() it is possible to update displayed text with set_item_label(), but there is no clear way to set the color of the displayed text.

Context: I'm trying to implement a dynamically updated table with selectable rows where color of values may change with each update and so far the only solution I found is to remove all rows and add them again with desired attributes.

I'd suggest that you start with the doc on themes (this will help with the selectable) and on item configuration (this one is for color on add_text).

Also please note that the selectable only paints its background in selected or hovered state. There's no way to fill its background in normal unselected non-hovered state (because it simply doesn't paint background in this state). Text color, on the other hand, should be easy to set up. Try adding dpg.show_style_editor() before start_dearpygui in your program to see what other colors are available.

Also note that tables support highlight_table_row, or alternatively you can bind a theme directly to the row in order to change its background color (and note that there are two background colors for rows - that's to implement striped tables).

Thanks for the idea with themes! So this would be the recommended approach here - define a collection of themes to apply to items as needed? I was thinking that just changing a color attribute can be a lighter approach.

It really depends on your needs and what you're going to do with that piece of UI in future. Setting the color on add_text is definitely a more lightweight approach - at the cost of flexibility though. Well, you can always start with just the color attribute, and change to themes if need be.
