3 /// Creates and runs a simple iterator plugin connected to TGeoPainter iterator.
4 ///
5 /// It demonstrates the possibility to dynamically change the color of drawn
6 /// volumes according some arbitrary criteria *WITHOUT* changing the color of the
7 /// same volume drawn on branches that do not match the criteria.

9 /// ~~~{.cpp}
10 /// To run:
11 /// root[0] .L iterplugin.cxx+
12 /// root[1] .x runplugin.C
13 /// root[2] select(2,kMagenta);
14 /// root[3] select(3,kBlue)
