Concept definition

template<typename F>
concept ove::lvgl::detail::StatelessCallable =  std::is_convertible_v<F, void (*)(lv_event_t *)>

Detailed Description

Concept satisfied by callables that are directly convertible to void(*)(lv_event_t*).

Only stateless lambdas and plain function pointers satisfy this concept. Capturing lambdas and functors with state do not, and must use the member-function-pointer overload of EventMixin::on() instead.

Template Parameters

F	The callable type to check.
