Hi
Templates donot create classes in windev ofr WX for that matter. Templates are windows or pages. These windows ( windev ) or Pages ( webdev) are used so other pages can be based on them.
So You make a template . In that template you put everything that is commen to a set of pages. This can be a navigation structure the styling ,etc
Then when you need a new page you create on using the template and you have a starting point. Nice feature is that if you change something in the template every page that uses that template changes as well. You can however override some template features if you want.
Hope this gives some insight.
regards
Allard
