RendererListFormattingProvider

public protocol RendererListFormattingProvider : AnyObject

Describes an object capable of providing style and formatting information for rendering lists in EditorView.

listLineFormatting
Line formatting to be used for a list item.
Declaration
Swift

var listLineFormatting: LineFormatting { get }


                    
                    
                    listLineMarkerFor(renderer:index:level:previousLevel:attributeValue:)

Returns the marker to be drawn for list item (bullet/number etc.) for given parameters.

Note

This function is called multiple times for same index level based on TextKit layout cycles. It is advisable to cache the values if calculation/drawing is performance intensive.

Declaration

Swift

func listLineMarkerFor(renderer: RendererView, index: Int, level: Int, previousLevel: Int, attributeValue: Any?) -> ListLineMarker

Parameters

`renderer`	Renderer in which list marker is being drawn.
`index`	Index of list item in the given list.
`level`	Indentation level of the list.
`previousLevel`	Previous indentation level. Using this, it can be determined if the list is being indented, outdented or is at same level.
`attributeValue`	Value of list item attribute for given index. Nil if there is no content set in list item yet.

Return Value

Marker to be drawn for the given list item.
