Hi all,

I would like that every example should be closed by a symbol of my 
choice (say, for example, a black triangle).


I tried what is suggested in this answer:

http://tex.stackexchange.com/questions/36791/including-end-mark-in-definitions-and-examples-using-amsthm

The suggested code works in a plain text file but if I try it in a lyx 
file I get an error saying that example is already defined, since lyx 
already defines it (the same error doesn't show for definition since 
the relative environment in lyx is called "defn").


So the question is: is there a way to use the package thmtools in lyx 
and avoid such problems?

Otherwise, how can I get my goal in lyx?

Thank you


In the preamble, prior to the line

\declaretheorem[style=definition,qed=$\blacktriangle$,sibling=definition]{example} 



insert the following:

\let\example\relax
