      Set swap interval.

    • setVSyncEnabled

      public void setVSyncEnabled(boolean enabled)

    • swapBuffers

      public void swapBuffers() throws LWJGLException
      Swap the canvas' buffer
      Throws:
      LWJGLException

    • isCurrent

      public boolean isCurrent() throws LWJGLException
      Description copied from interface: Drawable
      Returns true if the Drawable's context is current in the current thread.
      Specified by:
      isCurrent in interface Drawable
      Throws:
      LWJGLException

    • makeCurrent

      public void makeCurrent() throws LWJGLException
      Make the canvas' context current. It is highly recommended that the context is only made current inside the AWT thread (for example in an overridden paintGL()).
      Specified by:
      makeCurrent in interface Drawable
      Throws:
      LWJGLException

    • releaseContext

      public void releaseContext() throws LWJGLException
      Description copied from interface: Drawable
      If the Drawable's context is current in the current thread, no context will be current after a call to this method.
      Specified by:
      releaseContext in interface Drawable
      Throws:
      LWJGLException

    • destroy

      public final void destroy()
      Destroy the OpenGL context. This happens when the component becomes undisplayable
      Specified by:
      destroy in interface Drawable

    • setCLSharingProperties

      public final void setCLSharingProperties(PointerBuffer properties) throws LWJGLException
      Description copied from interface: Drawable
      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.
      Specified by:
      setCLSharingProperties in interface Drawable
      Parameters:
      properties - The target properties buffer. It must have at least 4 positions remaining.
      Throws:
      LWJGLException

    • initGL

      protected void initGL()
      Override this to do initialising of the context. It will be called once from paint(), immediately after the context is created and made current.

    • paintGL

      protected void paintGL()
      Override this to do painting

    • paint

      public final void paint(Graphics g)
      The default paint() operation makes the context current and calls paintGL() which should be overridden to do GL operations.
      Overrides:
      paint in class Canvas

    • exceptionOccurred

      protected void exceptionOccurred(LWJGLException exception)
      This method will be called if an unhandled LWJGLException occurs in paint(). Override this method to be notified of this.
      Parameters:
      exception - The exception that occurred.
