public class GestureDrag
extends GestureSingle

`GtkGestureDrag` is a `GtkGesture` implementation for drags.

The drag operation itself can be tracked throughout the
[signal@Gtk.GestureDrag::drag-begin],
[signal@Gtk.GestureDrag::drag-update] and
[signal@Gtk.GestureDrag::drag-end] signals, and the relevant
coordinates can be extracted through
[method@Gtk.GestureDrag.get_offset] and
[method@Gtk.GestureDrag.get_start_point].

onDragBegin

public SignalHandler onDragBegin(GestureDrag.OnDragBegin signal)

Connect to signal "drag-begin".
See GestureDrag.OnDragBegin.onDragBegin(double, double) for signal description.
Field SIGNAL_ON_DRAG_BEGIN 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.

onDragEnd

public SignalHandler onDragEnd(GestureDrag.OnDragEnd signal)

Connect to signal "drag-end".
See GestureDrag.OnDragEnd.onDragEnd(double, double) for signal description.
Field SIGNAL_ON_DRAG_END 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.

onDragUpdate

public SignalHandler onDragUpdate(GestureDrag.OnDragUpdate signal)

Connect to signal "drag-update".
See GestureDrag.OnDragUpdate.onDragUpdate(double, double) for signal description.
Field SIGNAL_ON_DRAG_UPDATE 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.
