How do i change the background colors of GUI elements like buttons or flows and panes? It doesn't look like that exists as part of luastyle.

This needs to be done by defining gui styles at data stage https://lua-api.factorio.com/latest/pro ... Style.html

Since the style prototype is limited to one total instance, how do i extend that?

Unless I'm just blind, also appears that most of the data-stage style specifications don't have background colors either.

It’s not a specific color code in the style, but part of the image set used by the style - in the PNG.

That's using ElementImageSetLayer?

I'll probably be able to understand that once i'm sober.

How do i add my new styles to the existing GUI style instance?

With other prototypes, you'd use something like

Code: Select all

local new_proto = table.deepcopy(data.raw[old_type][old_name])
new_proto.name = new_name
...
data:extend({new_proto})

With GUI-styles, this doesn't work. The only style that will be used is data.raw['gui-style'].default. However, you can add new styles to that! You don't even have to create everything from scratch, just pass on a 'parent' and all properties you don't set directly will be inherited. This is how I've defined styles in Autodrive:

Code: Select all

local styles = {}

-- Define button styles
styles.autodrive_button_off = {
  type = "button_style",
  parent = "shortcut_bar_button",
  padding = 4,
}

styles.autodrive_button_on = {
  type = "button_style",
  parent = "shortcut_bar_button_green",
  padding = 4,
}

-- Define textfield styles
styles.AD_highlighted_value_textfield = {
  type                  = "textbox_style",
  parent                = "highlighted_value_textfield",
  font                  = "default",
  font_color            = {},
}

styles.AD_stretchable_textfield = {
  type                  = "textbox_style",
  parent                = "stretchable_textfield",
  disabled_font         = "default-bold",
  disabled_font_color   = {1, 1, 1, 1},
}


styles.AD_inner_frame = {
    type = "frame_style",
    parent = "inside_shallow_frame_with_padding",
    vertically_stretchable = "on",
    horizontal_align = "center",
    vertical_align = "center",
}

-- Create styles
for s_name, s_data in pairs(styles) do
  data.raw['gui-style'].default[s_name] = s_data
end

Hope that helps!
