Example

The following example displays a picture called ARROWS in the region named ARROW. The picture consists of four segments representing four arrows. No hotspots are defined. The _getInfo method returns information about where in the picture a click occurred. That information is used to start a different application, depending on which arrow the user clicked.

length info 8;

INIT:
   arrow='sashelp.eisgrph.arrows.grseg';
return;

ARROW:
   if (_status_!=' ') then return;
   call notify('arrow','_get_info_',info);
   segment=getnitemn(info,'spotid');

      /* check to see if we really clicked
         on an arrow */
   if (segment=0) then return;

      /* run the selected application */
   select (segment);
      when (1) call display('north.frame');
      when (2) call display('west.frame');
      when (3) call display('east.frame');
      when (4) call display('south.frame');
   end;
