|
|
/// @param klass Class name of the application implementation. Must implement hdk::sdl::ApplicationInterface with Init,
|
|
/// Event, Iterate, and Quit methods.
|
|
/// @details This macro generates the SDL main entry point functions (SDL_AppInit, SDL_AppEvent, SDL_AppIterate,
|
|
/// SDL_AppQuit) that create an instance of the specified class and delegate to its methods. This allows users to write
|
|
/// their application logic in a clean class structure while still integrating with SDL's application lifecycle. The
|
|
/// generated main functions handle the boilerplate of managing the application instance and connecting it to SDL's
|
|
/// event loop and lifecycle callbacks.
