highlighteds property
This read-only property returns the read-only collection of highlighted parts.
Do not modify this collection. If you want to highlight or remove the highlight for a particular Part in a Diagram, set the Part#isHighlighted property. If you want to highlight a collection of Parts, call #highlightCollection. If you want to remove all highlights and highlight a single object, call #highlight. If you want to remove all highlights, call #clearHighlighteds.
Note that highlighteds collection and Part#isHighlighted property are completely independent of the #selection collection and the Part#isSelected property. No predefined command or tool operates on this highlighteds collection.
Implementation
_i3.Set<_i3.Part> get highlighteds => _i4.getProperty(
this,
'highlighteds',
);
