The StatusLine Class

Author: Jeff Stephenson

Date: 5 April 1988

 

The StatusLine Class

The StatusLine class provides a status line at the top of the screen which is programmer-definable. When enabled, it overlays the menu bar. The user may still access the menu by pressing Esc or positioning the mouse pointer in the status line end pressing the mouse button. The status line usually shows the player's score. To use a status line in a game, create an instance of class Code which has the interface described in code below and set the code property of StatusLine to it. To display the status line, execute (StatusLine enable:).
