GI.Gtk.Objects.EventControllerLegacy

EventControllerLegacy is an event controller that gives you direct access to the event stream. It should only be used as a last resort if none of the other event controllers or gestures do the job.

Exported types

newtype EventControllerLegacy

Memory-managed wrapper type.

class (GObject o, IsDescendantOf EventControllerLegacy o) => IsEventControllerLegacy o

Type class for types which can be safely cast to EventControllerLegacy, for instance with toEventControllerLegacy.

Instances

(GObject o, IsDescendantOf EventControllerLegacy o) => IsEventControllerLegacy o

Defined in GI.Gtk.Objects.EventControllerLegacy

toEventControllerLegacy :: (MonadIO m, IsEventControllerLegacy o) => o -> m EventControllerLegacy

Cast to EventControllerLegacy, for types for which this is known to be safe. For general casts, use castTo.

Methods

Overloaded methods

new

eventControllerLegacyNew

Arguments

:: (HasCallStack, MonadIO m)

=> m EventControllerLegacy

Returns: the newly created event controller.

Creates a new legacy event controller.

Signals

event

type C_EventControllerLegacyEventCallback = Ptr () -> Ptr Event -> Ptr () -> IO CInt

Type for the callback on the (unwrapped) C side.

type EventControllerLegacyEventCallback

Arguments

 = Event

event: the Event which triggered this signal

-> IO Bool

Returns: True to stop other handlers from being invoked for the event and the emission of this signal. False to propagate the event further.

Emitted for each GDK event delivered to controller.

afterEventControllerLegacyEvent :: (IsEventControllerLegacy a, MonadIO m) => a -> EventControllerLegacyEventCallback -> m SignalHandlerId

Connect a signal handler for the event signal, to be run after the default handler. When overloading is enabled, this is equivalent to

after eventControllerLegacy #event callback

genClosure_EventControllerLegacyEvent :: MonadIO m => EventControllerLegacyEventCallback -> m (GClosure C_EventControllerLegacyEventCallback)

Wrap the callback into a GClosure.

mk_EventControllerLegacyEventCallback :: C_EventControllerLegacyEventCallback -> IO (FunPtr C_EventControllerLegacyEventCallback)

Generate a function pointer callable from C code, from a C_EventControllerLegacyEventCallback.

noEventControllerLegacyEventCallback :: Maybe EventControllerLegacyEventCallback

A convenience synonym for Nothing :: Maybe EventControllerLegacyEventCallback.

onEventControllerLegacyEvent :: (IsEventControllerLegacy a, MonadIO m) => a -> EventControllerLegacyEventCallback -> m SignalHandlerId

Connect a signal handler for the event signal, to be run before the default handler. When overloading is enabled, this is equivalent to

on eventControllerLegacy #event callback

wrap_EventControllerLegacyEventCallback :: EventControllerLegacyEventCallback -> C_EventControllerLegacyEventCallback

Wrap a EventControllerLegacyEventCallback into a C_EventControllerLegacyEventCallback.
