GI.Gtk.Objects.GestureLongPress

GestureLongPress is a Gesture implementation able to recognize long presses, triggering the pressed after the timeout is exceeded.

If the touchpoint is lifted before the timeout passes, or if it drifts too far of the initial press point, the cancelled signal will be emitted.

Exported types

class (GObject o, IsDescendantOf GestureLongPress o) => IsGestureLongPress o

Type class for types which can be safely cast to GestureLongPress, for instance with toGestureLongPress.

(GObject o, IsDescendantOf GestureLongPress o) => IsGestureLongPress o

Defined in GI.Gtk.Objects.GestureLongPress

toGestureLongPress :: (MonadIO m, IsGestureLongPress o) => o -> m GestureLongPress

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

noGestureLongPress :: Maybe GestureLongPress

A convenience alias for Nothing :: Maybe GestureLongPress.

Methods

Overloaded methods

new

gestureLongPressNew

Arguments

:: (HasCallStack, MonadIO m, IsWidget a)

=> a

widget: a Widget

-> m GestureLongPress

Returns: a newly created GestureLongPress

Returns a newly created Gesture that recognizes long presses.

Since: 3.14

Properties

delayFactor

No description available in the introspection data.

constructGestureLongPressDelayFactor :: IsGestureLongPress o => Double -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “delay-factor” property. This is rarely needed directly, but it is used by new.

getGestureLongPressDelayFactor :: (MonadIO m, IsGestureLongPress o) => o -> m Double

Get the value of the “delay-factor” property. When overloading is enabled, this is equivalent to

get gestureLongPress #delayFactor

setGestureLongPressDelayFactor :: (MonadIO m, IsGestureLongPress o) => o -> Double -> m ()

Set the value of the “delay-factor” property. When overloading is enabled, this is equivalent to

set gestureLongPress [ #delayFactor := value ]

Signals

cancelled

type C_GestureLongPressCancelledCallback = Ptr () -> Ptr () -> IO ()

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

type GestureLongPressCancelledCallback = IO ()

This signal is emitted whenever a press moved too far, or was released before pressed happened.

Since: 3.14

afterGestureLongPressCancelled :: (IsGestureLongPress a, MonadIO m) => a -> GestureLongPressCancelledCallback -> m SignalHandlerId

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

after gestureLongPress #cancelled callback

genClosure_GestureLongPressCancelled :: MonadIO m => GestureLongPressCancelledCallback -> m (GClosure C_GestureLongPressCancelledCallback)

Wrap the callback into a GClosure.

mk_GestureLongPressCancelledCallback :: C_GestureLongPressCancelledCallback -> IO (FunPtr C_GestureLongPressCancelledCallback)

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

noGestureLongPressCancelledCallback :: Maybe GestureLongPressCancelledCallback

A convenience synonym for Nothing :: Maybe GestureLongPressCancelledCallback.

onGestureLongPressCancelled :: (IsGestureLongPress a, MonadIO m) => a -> GestureLongPressCancelledCallback -> m SignalHandlerId

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

on gestureLongPress #cancelled callback

wrap_GestureLongPressCancelledCallback :: GestureLongPressCancelledCallback -> C_GestureLongPressCancelledCallback

Wrap a GestureLongPressCancelledCallback into a C_GestureLongPressCancelledCallback.

pressed

type C_GestureLongPressPressedCallback = Ptr () -> CDouble -> CDouble -> Ptr () -> IO ()

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

type GestureLongPressPressedCallback

Arguments

 = Double

x: the X coordinate where the press happened, relative to the widget allocation

-> Double

y: the Y coordinate where the press happened, relative to the widget allocation

-> IO ()

This signal is emitted whenever a press goes unmoved/unreleased longer than what the GTK+ defaults tell.

Since: 3.14

afterGestureLongPressPressed :: (IsGestureLongPress a, MonadIO m) => a -> GestureLongPressPressedCallback -> m SignalHandlerId

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

after gestureLongPress #pressed callback

genClosure_GestureLongPressPressed :: MonadIO m => GestureLongPressPressedCallback -> m (GClosure C_GestureLongPressPressedCallback)

Wrap the callback into a GClosure.

mk_GestureLongPressPressedCallback :: C_GestureLongPressPressedCallback -> IO (FunPtr C_GestureLongPressPressedCallback)

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

noGestureLongPressPressedCallback :: Maybe GestureLongPressPressedCallback

A convenience synonym for Nothing :: Maybe GestureLongPressPressedCallback.

onGestureLongPressPressed :: (IsGestureLongPress a, MonadIO m) => a -> GestureLongPressPressedCallback -> m SignalHandlerId

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

on gestureLongPress #pressed callback

wrap_GestureLongPressPressedCallback :: GestureLongPressPressedCallback -> C_GestureLongPressPressedCallback

Wrap a GestureLongPressPressedCallback into a C_GestureLongPressPressedCallback.
