@Generated("io.github.jwharm.JavaGI")
public class GestureRotate
extends Gesture

GtkGestureRotate is a GtkGesture for 2-finger rotations.

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

Constructor Details

GestureRotate

public GestureRotate(MemorySegment address)

Create a GestureRotate proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

GestureRotate

public GestureRotate()

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

Method Details

getType

public static Type getType()

Get the GType of the GestureRotate class

Returns:

the GType

asParent

protected GestureRotate asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class Gesture

getAngleDelta

public double getAngleDelta()

Gets the angle delta in radians.

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

Returns:

the angle delta in radians

onAngleChanged

public SignalConnection<GestureRotate.AngleChangedCallback> onAngleChanged(GestureRotate.AngleChangedCallback handler)

Emitted when the angle between both tracked points changes.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• GestureRotate.AngleChangedCallback.run(double, double)

emitAngleChanged

public void emitAngleChanged(double angle,
 double angleDelta)

Emits the "angle-changed" signal. See onAngleChanged(org.gnome.gtk.GestureRotate.AngleChangedCallback).

builder

public static GestureRotate.Builder<? extends GestureRotate.Builder> builder()

A GestureRotate.Builder object constructs a GestureRotate with the specified properties. Use the various set...() methods to set properties, and finish construction with GestureRotate.Builder.build().
