[mapserver-users] Question about python mapscript and point style.

[Seth G]

Hi Vladimir,

Could you try the following syntax?

new_style = new mapscript.styleObj()
new_style.symbolname = 'circle'
new_style.size = 10
the_class.insertStyle(new_style)


Also make sure your variables aren't overriding the class names - e.g. maybe use different variable names than classObj. 

Regards,

Seth
