18\ingroup TEve
19Semi-abstract interface for classes supporting secondary-selection.
20
21Element class that inherits from this, should also implement the
22following virtual methods from TEveElement:
23~~~ {.cpp}
24 virtual void UnSelected();
25 virtual void UnHighlighted();
26~~~
27and clear corresponding selection-set from there.
28
29To support tooltips for sub-elements, implement:
30~~~ {.cpp}
31 virtual TString TEveElement::GetHighlightTooltip();
32~~~
33and return tooltip for the entry in the fHighlightedSet.
34There should always be a single entry there.
35See TEveDigitSet for an example.
