Secure frame visibility question.

[dorn]

I'm trying to learn how to use the secure templates/handlers and I've hit something confusing. Everything I read implies hiding/showing action frames in combat is restricted to macro conditionals.

How do things like OPie work though? You press a hotkey and an action frame appears then executes whatever radial choice you make. I know Aura Frames also has a popup cancel-buffs-in-combat frame as well.

I've tried looking through the code of such addons but it's a bit much to tackle all at once. Am I misunderstanding the hide/show restrictions or something? Any help is appreciated.
