SECEditViewport Class

class SECEditViewport: public MvcViewport

SECEditViewport is the view for Objective Edit.

The SECEditViewport class is a derivative of the MVC architecture that depends upon a model and has a controller. A viewport is conceptually similar to a CView class. It's most important difference is it isn't a window (or CWnd derivative). A CWnd class aggregates a viewport and delegates the rendering to the viewport class.

The SECEditCtrl and SECEditView classes aggregate the CWnd and CView classes through the SECEditCtrlWrapper_T and SECEditViewWrapper_T template classes, respectively.
