SDL.Event

SDL.Event exports an interface for working with the SDL event model. Event handling allows your application to receive input from the user. Internally, SDL stores all the events waiting to be handled in an event queue. Using functions like pollEvent and waitEvent you can observe and handle waiting input events.

The event queue itself is composed of a series of Event values, one for each waiting event. Event values are read from the queue with the pollEvent function and it is then up to the application to process the information stored with them.

Polling events

6 declarations

valuepollEvent :: MonadIO m => m (Maybe Event)

Poll for currently pending events. You can only call this function in the OS thread that set the video mode.

valuepollEvents :: MonadIO m => m [Event]

Clear the event queue by polling for all pending events.

Like pollEvent this function should only be called in the OS thread which set the video mode.

valuemapEvents :: MonadIO m => (Event -> m ()) -> m ()

Run a monadic computation, accumulating over all known Events.

This can be useful when used with a state monad, allowing you to fold all events together.

valuepumpEvents :: MonadIO m => m ()

Pump the event loop, gathering events from the input devices.

This function updates the event queue and internal input device state.

This should only be run in the OS thread that initialized the video subsystem, and for extra safety, you should consider only doing those things on the main thread in any case.

pumpEvents gathers all the pending input information from devices and places it in the event queue. Without calls to pumpEvents no events would ever be placed on the queue. Often the need for calls to pumpEvents is hidden from the user since pollEvent and waitEvent implicitly call pumpEvents. However, if you are not polling or waiting for events (e.g. you are filtering them), then you must call pumpEvents to force an event queue update.

See SDL_PumpEvents for C documentation.

valuewaitEvent :: MonadIO m => m Event

Wait indefinitely for the next available event.

valuewaitEventTimeout

:: MonadIO m
=> CInt
The maximum amount of time to wait, in milliseconds.
-> m (Maybe Event)

Wait until the specified timeout for the next available amount.

Registering user events

5 declarations

datadata RegisteredEventType a

A user defined event structure that has been registered with SDL.

Use registerEvent, below, to obtain an instance.

Constructors

RegisteredEventType
- pushRegisteredEvent :: a -> IO EventPushResult
- getRegisteredEvent :: Event -> IO (Maybe a)

datadata RegisteredEventData

A record used to convert between SDL Events and user-defined data structures.

Used for registerEvent, below.

Constructors

RegisteredEventData
- registeredEventWindow :: !Maybe Window
  The associated Window.
- registeredEventCode :: !Int32
  User defined event code.
- registeredEventData1 :: !Ptr ()
  User defined data pointer.
- registeredEventData2 :: !Ptr ()
  User defined data pointer.

valueemptyRegisteredEvent :: RegisteredEventData

A registered event with no associated data.

This is a resonable baseline to modify for converting to RegisteredEventData.

valueregisterEvent

:: MonadIO m
=> RegisteredEventData -> Timestamp -> IO (Maybe a)
-> a -> IO RegisteredEventData
-> m (Maybe (RegisteredEventType a))

Provide functions that convert between UserEventData and your structure. You can then use pushRegisteredEvent to add a custom event of the registered type to the queue, and getRegisteredEvent to test for such events in the main loop.

Watching events

4 declarations

typetype EventWatchCallback = Event -> IO ()

An EventWatchCallback can process and respond to an event when it is added to the event queue.

newtypenewtype EventWatch

valueaddEventWatch :: MonadIO m => EventWatchCallback -> m EventWatch

Trigger an EventWatchCallback when an event is added to the SDL event queue.

See https://wiki.libsdl.org/SDL_AddEventWatch for C documentation.

valuedelEventWatch :: MonadIO m => EventWatch -> m ()

Remove an EventWatch.

See https://wiki.libsdl.org/SDL_DelEventWatch for C documentation.

3 declarations

datadata Event

A single SDL event. This event occurred at eventTimestamp and carries data under eventPayload.

Constructors
