GI.Gtk.Objects.GestureLongPress

GestureLongPress is a Gesture implementation able to recognize long presses, triggering the GestureLongPress::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 GestureLongPress::cancelled signal will be emitted.

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

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.

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 GestureLongPress::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 :: GestureLongPressCancelledCallback -> IO Closure

Wrap the callback into a Closure.

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 :: GestureLongPressPressedCallback -> IO Closure

Wrap the callback into a Closure.

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.
