[scilab-Users] Graphic interfaces

[Jean-Louis Auge]

Ok, it is working!
I used the tag property.
I discovered that SCILAB (findobj function) looks for in the code 
everywhere and that whatever the location of the tag (function in a 
function).
The notion of the local or global variable do not exist for the research 
of the tag with the findobject function.

Thank you for your help.

Best regards.
