Detailed Description

Function Documentation

ApplyStrokeMarkerPrefab()

bool donner::editor::ApplyStrokeMarkerPrefab	(	EditorApp &	app,
		std::string_view	property,
		StrokeMarkerPrefab	prefab )

Attach a reusable marker to the selected shapes, creating its SVG definition on first use.

The marker uses context-stroke so its color follows the shape. A later use of the same preset reuses the existing tagged definition; an unrelated element with the preferred ID is preserved. Definition insertion and the style change form one source-backed undo entry.

Parameters

app	Editor containing the selected shapes and SVG document.
property	Either marker-start or marker-end.
prefab	Preset to use.

Returns

True when a document mutation was queued.
