SDL event
keyEvent :: WrappedEvent -> WrappedEvent Source #
Filter any key events
keyDownEvent :: WrappedEvent -> Event Keysym Source #
Event carrying the key pressed down
keyUpEvent :: WrappedEvent -> Event Keysym Source #
Event carrying the key pressed up
mouseEvent :: WrappedEvent -> WrappedEvent Source #
Filter any mouse event (button or move)
mouseButtonEvent :: WrappedEvent -> WrappedEvent Source #
Mouse button event
keyFilter :: Keycode -> EventPayload -> Bool Source #
Filter an event on a particular key being held down
keyUpFilter :: Keycode -> EventPayload -> Bool Source #
Filter an event on a particular key being released
mouseEventWithin :: Rect -> WrappedEvent -> WrappedEvent Source #
Mouse event occuring inside a given area
tickDiffEvent :: SDLEventSource -> MomentIO TickEvent Source #
Event carrying the difference between the last two SDL ticks.
