Description

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.

Methods

new

gestureLongPressNew Source #

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) Source #

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 Source #

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 () Source #

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 () Source #

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

type GestureLongPressCancelledCallback = IO () Source #

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 Source #

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 Source #

Wrap the callback into a Closure.

mk_GestureLongPressCancelledCallback :: C_GestureLongPressCancelledCallback -> IO (FunPtr C_GestureLongPressCancelledCallback) Source #

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

noGestureLongPressCancelledCallback :: Maybe GestureLongPressCancelledCallback Source #

A convenience synonym for Nothing :: Maybe GestureLongPressCancelledCallback.

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

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 Source #

Wrap a GestureLongPressCancelledCallback into a C_GestureLongPressCancelledCallback.

pressed

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

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

type GestureLongPressPressedCallback Source #

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 Source #

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 Source #

Wrap the callback into a Closure.

mk_GestureLongPressPressedCallback :: C_GestureLongPressPressedCallback -> IO (FunPtr C_GestureLongPressPressedCallback) Source #

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

noGestureLongPressPressedCallback :: Maybe GestureLongPressPressedCallback Source #

A convenience synonym for Nothing :: Maybe GestureLongPressPressedCallback.

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

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 Source #

Wrap a GestureLongPressPressedCallback into a C_GestureLongPressPressedCallback.
