Event-handling for spinner selection

[Phuc ho quang]

Hi I'm new to kivy and I'm in trouble of using Spinner. I should say that i can't find what is the event to use for the spinner when i changed the selection of the spinner? Someone in Stackoverflow said that I should try on_text but where can i found it on the documentation? And Are there any other event trigger for spinner, where can i find them

[ZenCODE]

'on_text' should work. It's automatically provided because text is a StringProperty. The Spinner inherits this property as it is a subclass of Button. Hope that helps?
