GI.Gtk.Objects.EventControllerLegacy

Description

GtkEventControllerLegacy is an event controller that provides raw 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.

Synopsis

Exported types

newtype EventControllerLegacy Source #

Memory-managed wrapper type.

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

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

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

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

Methods

new

eventControllerLegacyNew Source #

Arguments

:: (HasCallStack, MonadIO m) 
=> m EventControllerLegacy

Returns: the newly created event controller.

Creates a new legacy event controller.

Signals

event

type EventControllerLegacyEventCallback Source #

Arguments

 = Event

event: the GdkEvent 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 -> ((?self :: a) => EventControllerLegacyEventCallback) -> m SignalHandlerId Source #

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

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onEventControllerLegacyEvent :: (IsEventControllerLegacy a, MonadIO m) => a -> ((?self :: a) => EventControllerLegacyEventCallback) -> m SignalHandlerId Source #

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
