Re: [cgmo-webcgm] Need help with WebCGM Events!

["Ulrich Laesche" <ulrich@ematek.de>]

Hello Benoit,

Attached are two samples from the MetaWeb API (& sample CGM file, but you
could use whatever version 4 file you want).  test_API_4 utilizes most of
the events we have implemented into MetaWeb already.  This sample is quite
academic (a better word for useless) though.  test_API_5 shows how we
implemented highlighting of a certain Application Structure.

Hope this helps and best regards
Ulrich
