  • Method Summary

    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.

  • Method Details

    • isCurrent

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

    • makeCurrent

      void makeCurrent() throws LWJGLException
      Makes the Drawable's context 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
