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