LayoutLineRef

public struct LayoutLineRef : LayoutLineProtocol

A PangoLayoutLine represents one of the lines resulting from laying out a paragraph via PangoLayout.

PangoLayoutLine structures are obtained by calling [methodPango.Layout.get_line] and are only valid until the text, attributes, or settings of the parent PangoLayout are modified.

The LayoutLineRef type acts as a lightweight Swift reference to an underlying PangoLayoutLine instance. It exposes methods that can operate on this data type through LayoutLineProtocol conformance. Use LayoutLineRef only as an unowned reference to an existing PangoLayoutLine instance.

  • ptr 
    Untyped pointer to the underlying `PangoLayoutLine` instance.

    For type-safe access, use the generated, typed pointer layout_line_ptr property instead.
