GI.Gtk.Objects.GestureLongPress

Description

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.

Synopsis

Exported types

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

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

Instances

(GObject o, IsDescendantOf GestureLongPress o) => IsGestureLongPress o Source # 
Instance details

Defined in GI.Gtk.Objects.GestureLongPress

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

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

Methods

Overloaded 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.

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 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

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

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

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
