Class DISPLAY_DEVICE

java.lang.Object
org.lwjgl.system.Pointer.Default
org.lwjgl.system.Struct<DISPLAY_DEVICE>
org.lwjgl.system.windows.DISPLAY_DEVICE
All Implemented Interfaces:
AutoCloseable, org.lwjgl.system.NativeResource, org.lwjgl.system.Pointer
public class DISPLAY_DEVICE extends org.lwjgl.system.Struct<DISPLAY_DEVICE> implements org.lwjgl.system.NativeResource
Receives information about the display device specified by the iDevNum parameter of the User32.EnumDisplayDevices(java.nio.ByteBuffer, int, org.lwjgl.system.windows.DISPLAY_DEVICE, int) function.

The four string members are set based on the parameters passed to EnumDisplayDevices. If the lpDevice param is NULL, then DISPLAY_DEVICE is filled in with information about the display adapter(s). If it is a valid device name, then it is filled in with information about the monitor(s) for that device.

    • DISPLAY_DEVICE

      public DISPLAY_DEVICE(ByteBuffer container)
      Creates a DISPLAY_DEVICE 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.
