Detailed Description

template<typename Derived>
class ove::lvgl::StyleMixin< Derived >

CRTP mixin that adds inline per-object style setters to widget classes.

Each method applies a single style property directly to the LV_PART_MAIN part of the underlying LVGL object and returns Derived & to support method chaining. These are convenience wrappers around the LVGL lv_obj_set_style_* family of functions.

Template Parameters

Derived The concrete widget class inheriting this mixin. Must expose a get() method returning lv_obj_t*.
