org.lwjgl.system.Struct

org.lwjgl.openvr.VREventScroll

All Implemented Interfaces:

org.lwjgl.system.Pointer

public class VREventScroll
extends org.lwjgl.system.Struct

Used for simulated mouse wheel scroll.

Member documentation

• xdelta – movement in fraction of the pad traversed since last delta, 1.0 for a full swipe
• viewportscale – for scrolling on an overlay with laser mouse, this is the overlay's vertical size relative to the overlay height. Range: [0,1]

Layout

 struct VREvent_Scroll_t {
     float xdelta;
     float ydelta;
     uint32_t unused;
     float viewportscale;
 }

Constructor Detail

VREventScroll

public VREventScroll(java.nio.ByteBuffer container)

Creates a VREventScroll instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

The created instance holds a strong reference to the container object.

Method Detail

sizeof

public int sizeof()

Specified by:

sizeof in class org.lwjgl.system.Struct

xdelta

public float xdelta()

Returns the value of the xdelta field.

ydelta

public float ydelta()

Returns the value of the ydelta field.

unused

public int unused()

Returns the value of the unused field.

viewportscale

public float viewportscale()

Returns the value of the viewportscale field.

create

public static VREventScroll create(long address)

Returns a new VREventScroll instance for the specified memory address.

createSafe

@Nullable
public static VREventScroll createSafe(long address)

Like create, but returns null if address is NULL.

create

public static VREventScroll.Buffer create(long address,
                                          int capacity)

Create a VREventScroll.Buffer instance at the specified memory.

Parameters:

address - the memory address

capacity - the buffer capacity

createSafe

@Nullable
public static VREventScroll.Buffer createSafe(long address,
                                              int capacity)

Like create, but returns null if address is NULL.

nxdelta

public static float nxdelta(long struct)

Unsafe version of xdelta().

nydelta

public static float nydelta(long struct)

Unsafe version of ydelta().

nunused

public static int nunused(long struct)

Unsafe version of unused().

nviewportscale

public static float nviewportscale(long struct)

Unsafe version of viewportscale().
