public class GestureLongPress
extends GestureSingle

`GtkGestureLongPress` is a `GtkGesture` for long presses.

This gesture is also known as “Press and Hold”.

When the timeout is exceeded, the gesture is triggering the
[signal@Gtk.GestureLongPress::pressed] signal.

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

How long the timeout is before the ::pressed signal gets emitted is
determined by the [property@Gtk.Settings:gtk-long-press-time] setting.
It can be modified by the [property@Gtk.GestureLongPress:delay-factor]
property.

getDelayFactor

public double getDelayFactor()

Returns the delay factor.

Returns:

the delay factor

setDelayFactor

public void setDelayFactor(double delay_factor)

signal - callback function (lambda).

Returns:

SignalHandler. Can be used to disconnect signal and to release callback function.

onPressed

public SignalHandler onPressed(GestureLongPress.OnPressed signal)

Connect to signal "pressed".
See GestureLongPress.OnPressed.onPressed(double, double) for signal description.
Field SIGNAL_ON_PRESSED contains original signal name and can be used as resource reference.

Parameters:

signal - callback function (lambda).

Returns:

SignalHandler. Can be used to disconnect signal and to release callback function.
