      Modifier and Type Method Description
      void destroy()
      Destroys the Drawable.
      boolean isCurrent()
      Returns true if the Drawable's context is current in the current thread.
      void makeCurrent()
      Makes the Drawable's context current in the current thread.
      void releaseContext()
      If the Drawable's context is current in the current thread, no context will be current after a call to this method.
      void setCLSharingProperties​(PointerBuffer properties)
      Sets the appropriate khr_gl_sharing properties in the target PointerBuffer, so that if it is used in a clCreateContext(FromType) call, the created CL context will be sharing objects with this Drawable's GL context.

      • isCurrent

        boolean isCurrent()
                   throws LWJGLException
        Returns true if the Drawable's context is current in the current thread.
        Throws:
        LWJGLException
      • releaseContext

        void releaseContext()
                     throws LWJGLException
        If the Drawable's context is current in the current thread, no context will be current after a call to this method.
        Throws:
        LWJGLException
      • destroy

        void destroy()
        Destroys the Drawable.
      • setCLSharingProperties

        void setCLSharingProperties​(PointerBuffer properties)
                             throws LWJGLException
        Sets the appropriate khr_gl_sharing properties in the target PointerBuffer, so that if it is used in a clCreateContext(FromType) call, the created CL context will be sharing objects with this Drawable's GL context. After a call to this method, the target buffer position will have advanced by 2 to 4 positions, depending on the implementation.
        Parameters:
        properties - The target properties buffer. It must have at least 4 positions remaining.
        Throws:
        LWJGLException
