Interface LibDwmApi

  • All Superinterfaces:
    com.sun.jna.Library
    public interface LibDwmApi
extends com.sun.jna.Library
    JNA interface to the native LibDwm (Desktop Window Manager) library.

    This library is only available on Windows platforms.

    The functionality provided by this library may be helpful especially when working with full-screen exclusive mode in Java which suffers from numerous idiosyncrasies on Windows, some of which can be mitigated by ensuring that desktop window composition is disabled. Disabling composition can be done at the operating system level, but is more convenient for end-users if the application itself does it.

    This class may be removed in future versions of vlcj due to it's uselessness.
