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.

new

=> 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, MonadIO m) => Double -> m (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 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 -> ((?self :: 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

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onGestureLongPressCancelled :: (IsGestureLongPress a, MonadIO m) => a -> ((?self :: 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

pressed

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 -> ((?self :: 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

By default the object invoking the signal is not passed to the callback. If you need to access it, you can use the implit ?self parameter. Note that this requires activating the ImplicitParams GHC extension.

onGestureLongPressPressed :: (IsGestureLongPress a, MonadIO m) => a -> ((?self :: 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
