More on this later).In this system, CFrame is the parent class of all other deriving classes (CDialog, CField) and the ancestor of the other three (CLabel, CLine, CButton). === Responsibilities ===CFrame is responsible for common communication with the underlying console including:* Clearing a portion of the screen (draw)** Optionally drawing a border/frame while doing this* Restoring a section of a cleared portion of the screen or in its entirety (hide)* Storing attributes and providing functionality for retrieving the basic state of the frame including:** Whether it is in fullscreen mode** Whether it is bordered** Relative top left row/top left column** Absolute top left row/top left column** Width/height of the frame, including the frame/border*** This should be the width/height of the screen if the frame is in fullscreen
