This class contains settings that are used by several other class (including some singletons).
static int joystickNumButtons(SDL_Joystick *joystick)
Normally the following two functions simply delegate to SDL_JoystickNumButtons() and SDL_JoystickGetB...
InputEventGenerator(const InputEventGenerator &)=delete
BooleanSetting & getGrabInput()
Input Grab on or off.
static bool joystickGetButton(SDL_Joystick *joystick, int button)
void updateGrab(bool grab)
Must be called when 'grabinput' or 'fullscreen' setting changes.
void wait()
Wait for event(s) and handle it.
InputEventGenerator & operator=(const InputEventGenerator &)=delete
KeyCode
Constants that identify keys and key modifiers.
Definition: Keys.hh:26
This file implemented 3 utility functions:
Definition: Autofire.cc:9
constexpr void repeat(T n, Op op)
Repeat the given operation 'op' 'n' times.
