All Implemented Interfaces:

PointerInterface

public class GestureRotate
extends Gesture

`GtkGestureRotate` is a `GtkGesture` for 2-finger rotations.

Whenever the angle between both handled sequences changes, the
[signal@Gtk.GestureRotate::angle-changed] signal is emitted.

Constructor Details

GestureRotate

public GestureRotate(PointerContainer pointer)

GestureRotate

public GestureRotate()

Returns a newly created `GtkGesture` that recognizes 2-touch
rotation gestures.

Method Details

getClassHandler

public static ClassHandler getClassHandler()

getAngleDelta

public double getAngleDelta()

Gets the angle delta in radians.

If @gesture is active, this function returns the angle difference
in radians since the gesture was first recognized. If @gesture is
not active, 0 is returned.

Returns:

the angle delta in radians

onAngleChanged

public SignalHandler onAngleChanged(GestureRotate.OnAngleChanged signal)

Connect to signal "angle-changed".
See GestureRotate.OnAngleChanged.onAngleChanged(double, double) for signal description.
Field SIGNAL_ON_ANGLE_CHANGED 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.

getTypeID

public static long getTypeID()

getParentTypeID

public static long getParentTypeID()

getTypeSize

public static TypeSystem.TypeSize getTypeSize()

getParentTypeSize

public static TypeSystem.TypeSize getParentTypeSize()

getInstanceSize

public static int getInstanceSize()
