Package org.lwjgl.system.windows

Class DISPLAY_DEVICE

  • All Implemented Interfaces:
    java.lang.AutoCloseable, org.lwjgl.system.NativeResource, org.lwjgl.system.Pointer
    public class DISPLAY_DEVICE
extends org.lwjgl.system.Struct
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.

    • Constructor Detail

      • DISPLAY_DEVICE

        public DISPLAY_DEVICE​(java.nio.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.
