Member Function Documentation

virtual void OpenGLRenderer::newOpenGLContextCreated ( )

pure virtual

Called when a new GL context has been created.

You can use this as an opportunity to create your textures, shaders, etc. When the method is invoked, the new GL context will be active. Note that this callback will be made on a background thread, so make sure that your implementation is thread-safe.

virtual void OpenGLRenderer::renderOpenGL ( )

pure virtual

Called when you should render the next openGL frame.

Note that this callback will be made on a background thread, not the message thread, so make sure that your implementation is thread-safe. If the context is attached to a component in order to do component rendering, then the MessageManager may be locked when this callback is made. For information about how to trigger a render callback, see OpenGLContext::triggerRepaint() and OpenGLContext::setContinuousRepainting().

virtual void OpenGLRenderer::openGLContextClosing ( )

pure virtual

Called when the current openGL context is about to close.

You can use this opportunity to release any GL resources that you may have created.

Note that this callback will be made on a background thread, so make sure that your implementation is thread-safe.

(Also note that on Android, this callback won't happen, because there's currently no way to implement it..)
