Next, you add the setMin:
,
setMax:
and setTitle:
setters to the initializeMeter:
callback method. You also send the event:
message, with an
argument, #display
. The event:
message tells the meter pane
to act as though the event, #display
, has occurred:
CalorieViewManager method definition instance initializeMeter: theMeter theMeter setMin: 0; setMax: 100; setTitle: 'Calorie Meter'; event: #display.
From the definition of createViews
in Segment 705,
you know that the response to the event:
message, with a
#display
argument, is to send the callDrawMeter:
message to
the view manager, thus drawing the meter.
