@Generated("org.javagi.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 instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static @Nullable Type getType()

Get the GType of the TouchpadEvent class.

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected TouchpadEvent asParent()

Return this instance as if it were its parent type. Comparable to the Java super keyword, but ensures the parent typeclass is also used in native code.

Overrides:

asParent in class Event

Returns:

the instance as if it were its parent type

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
