[Sgems-devel] how to issue a warning message

[RENARD P. <Phi...@un...>]

Hi !

I wonder how to issue a warning message during the execution of an
algorithm. For example when the algorithm find something suspicious but
when it can still do its work ? I'd like to have a nice popup window
that tells the user that the algoritm did encounter a problem.

I also wonder how GsTLcerr works ? When I redirect a message to GsTLcerr
I don't see it anywhere. Is there any initilization that should be done
prior to use it ?

Cheers, Philippe
