Proxy

@Generated("io.github.jwharm.JavaGI")
public class TouchpadEvent
extends Event

An event related to a gesture on a touchpad device.

Unlike touchscreens, where the windowing system sends basic sequences of begin, update, end events, and leaves gesture recognition to the clients, touchpad gestures are typically processed by the system, resulting in these events.

Constructor Details

TouchpadEvent

public TouchpadEvent(MemorySegment address)

Create a TouchpadEvent proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static Type getType()

Get the GType of the TouchpadEvent class

Returns:

the GType

asParent

protected TouchpadEvent 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 Event

getDeltas

public void getDeltas(Out<Double> dx,
 Out<Double> dy)

Extracts delta information from a touchpad event.

Parameters:

dx - return location for x

dy - return location for y

getGesturePhase

public TouchpadGesturePhase getGesturePhase()

Extracts the touchpad gesture phase from a touchpad event.

Returns:

the gesture phase of this TouchpadEvent

getNFingers

public int getNFingers()

Extracts the number of fingers from a touchpad event.

Returns:

the number of fingers for this TouchpadEvent

getPinchAngleDelta

public double getPinchAngleDelta()

Extracts the angle delta from a touchpad pinch event.

Returns:

the angle delta of this TouchpadEvent

getPinchScale

public double getPinchScale()

Extracts the scale from a touchpad pinch event.

Returns:

the scale of this TouchpadEvent
