UISelectionList Theming Parameters

UISelectionList theming block id is 'selection_list'.



A diagram of which part of the element is themed by which colour parameter.

UISelectionList makes use of the following these colour parameters in a 'colours' block. All of these colours can also be a colour gradient:

  • "dark_bg" - The background colour/gradient of the selection list element. Often you won't see this unless your list buttons are semi-transparent.

  • "normal_border" - The colour/gradient of the border around the selection list (if it has one).


UISelectionList accepts the following miscellaneous parameters in a 'misc' block:

  • "shape" - Can be one of 'rectangle' or 'rounded_rectangle'. Different shapes for this UI element.

  • "shape_corner_radius" - Only used if our shape is 'rounded_rectangle'. It sets the radius, or radii, used for the rounded corners. Use a single integer to set all corners to the same radius, or four integers separated by commas to set each corner individually.

  • "border_width" - The width of the border around the element in pixels. Defaults to "1".

  • "shadow_width" - The width of the shadow around the element in pixels. Defaults to "2".

  • "list_item_height" - The pixel height of a the items in the list. Defaults to "20".

  • "tool_tip_delay" - time in seconds before the button's tool tip (if it has one) will appear. Default is "1.0".


The selection list may also contain a UIVerticalScrollBar which you can reference with the block id 'window.vertical_scroll_bar'. You can also reference all of the buttons that are sub elements of the scroll bar with a theming block id of 'window.vertical_scroll_bar.button', or pick out the list item buttons specifically with a class_id of '@selection_list_item'.

You can further reference the individual buttons of the scroll bar by adding their object IDs:

  • 'window.vertical_scroll_bar.#top_button'

  • 'window.vertical_scroll_bar.#bottom_button'

  • 'window.vertical_scroll_bar.#sliding_button'

There is more information on theming the vertical scroll bar at UIVerticalScrollBar Theming Parameters.
