Display Methods on Time_Object

 

     

TIME_OBJECT * timeobj

Display the time section of the geometry for time * time, it is created by calling "get-object" (see 4.4.4) and stored in inter which then is displayed.

Both methods are identical (in fact "display" just calls "geometry-disp"), but subclasses with more than one geometry might replace "display" and then the geometry still can be displayed with "geometry-disp".

        

TIME_OBJECT * time_object
CHAIN * geom

These methods split the graphics window in several sub-windows and calls "display" for different times for each of them. "multi-disp" adds some rulers to the option menu which allow to control the time-range (relative to the current time), the number of pictures and an additional horizontal and vertical distance between them. "muli-disp" then calls "multi-display" which then calls "do-multi-disp" with geometry as parameter.

This construction may seem a litte bit complicated, but is simplifies implementing this method for subclasses: only "multi-display" which calls "do-multi-disp" with the correct parameter has to be provided.
