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
- newtype EventControllerLegacy = EventControllerLegacy (ManagedPtr EventControllerLegacy)
- class (GObject o, IsDescendantOf EventControllerLegacy o) => IsEventControllerLegacy o
- toEventControllerLegacy :: (MonadIO m, IsEventControllerLegacy o) => o -> m EventControllerLegacy
- eventControllerLegacyNew :: (HasCallStack, MonadIO m) => m EventControllerLegacy
- type EventControllerLegacyEventCallback = Event -> IO Bool
- afterEventControllerLegacyEvent :: (IsEventControllerLegacy a, MonadIO m) => a -> ((?self :: a) => EventControllerLegacyEventCallback) -> m SignalHandlerId
- onEventControllerLegacyEvent :: (IsEventControllerLegacy a, MonadIO m) => a -> ((?self :: a) => EventControllerLegacyEventCallback) -> m SignalHandlerId
Exported types
newtype EventControllerLegacy Source #
Memory-managed wrapper type.
EventControllerLegacy (ManagedPtr EventControllerLegacy) |
Instances
class (GObject o, IsDescendantOf EventControllerLegacy o) => IsEventControllerLegacy o Source #
Type class for types which can be safely cast to EventControllerLegacy
, for instance with toEventControllerLegacy
.
Instances
(GObject o, IsDescendantOf EventControllerLegacy o) => IsEventControllerLegacy o Source # | |
Defined in GI.Gtk.Objects.EventControllerLegacy |
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
.

new
eventControllerLegacyNew Source #
:: (HasCallStack, MonadIO m) | |
=> m EventControllerLegacy | Returns: the newly created event controller. |
Creates a new legacy event controller.
Signals
event
type EventControllerLegacyEventCallback Source #
= Event |
|
-> IO Bool | Returns: |
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
