MGR is/was used as a light-weight GUI system for low-powered PC systems running Coherent , Linux , BSD Unix or VSTa .


FEATURES


MGR provides each client window with:

  • Termcap -style terminal control functions, graphics primitives such as line and circle drawing;

  • facilities for manipulating bitmaps, Fonts , Icons , and pop-up Menus ;

  • commands to reshape and position windows; and a Message Passing facility enabling client programs to rendezvous and exchange messages. Client programs may ask to be informed when a change in the window system occurs, such as a reshaped window, a pushed Mouse Button , or a message sent from another client program. These changes are called Events . MGR notifies a client program of an event by sending it an ASCII character string in a Format specified by the client program. Existing Applications can be integrated into the windowing environment without modification by having MGR imitate keystrokes in response to user defined menu selections or other events.
