GI.Gtk.Objects.EventControllerLegacy
Description
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.
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 C_EventControllerLegacyEventCallback = Ptr () -> Ptr Event -> Ptr () -> IO CInt
- type EventControllerLegacyEventCallback = Event -> IO Bool
- afterEventControllerLegacyEvent :: (IsEventControllerLegacy a, MonadIO m) => a -> EventControllerLegacyEventCallback -> m SignalHandlerId
- genClosure_EventControllerLegacyEvent :: MonadIO m => EventControllerLegacyEventCallback -> m (GClosure C_EventControllerLegacyEventCallback)
- mk_EventControllerLegacyEventCallback :: C_EventControllerLegacyEventCallback -> IO (FunPtr C_EventControllerLegacyEventCallback)
- noEventControllerLegacyEventCallback :: Maybe EventControllerLegacyEventCallback
- onEventControllerLegacyEvent :: (IsEventControllerLegacy a, MonadIO m) => a -> EventControllerLegacyEventCallback -> m SignalHandlerId
- wrap_EventControllerLegacyEventCallback :: EventControllerLegacyEventCallback -> C_EventControllerLegacyEventCallback
Exported types
newtype EventControllerLegacy Source #
Memory-managed wrapper type.
Constructors
| 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.
Methods
Overloaded 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 C_EventControllerLegacyEventCallback = Ptr () -> Ptr Event -> Ptr () -> IO CInt Source #
Type for the callback on the (unwrapped) C side.
type EventControllerLegacyEventCallback Source #
Arguments
| = Event |
|
| -> IO Bool | Returns: |
Emitted for each GDK event delivered to controller.
afterEventControllerLegacyEvent :: (IsEventControllerLegacy a, MonadIO m) => 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
genClosure_EventControllerLegacyEvent :: MonadIO m => EventControllerLegacyEventCallback -> m (GClosure C_EventControllerLegacyEventCallback) Source #
Wrap the callback into a GClosure.
mk_EventControllerLegacyEventCallback :: C_EventControllerLegacyEventCallback -> IO (FunPtr C_EventControllerLegacyEventCallback) Source #
Generate a function pointer callable from C code, from a C_EventControllerLegacyEventCallback.
noEventControllerLegacyEventCallback :: Maybe EventControllerLegacyEventCallback Source #
A convenience synonym for Nothing :: Maybe EventControllerLegacyEventCallback
onEventControllerLegacyEvent :: (IsEventControllerLegacy a, MonadIO m) => 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
