Flash Player 6 r65.
This class is an extension of FMXISRoundDial that provides round
dial functionality with a rate-limited needle (based on a user-specified needle
rate). Developers can set its value in two ways. First, by setting the val
property to have the dial jump immediately to that value. Second, by setting
the targVal property, the dial will reach the target value based
on the set needle rate (needleRate). For convenience, the gauge
generates an event, onReachTarg when it reaches the target value
(only if set using targVal). The event name can be changed (if
desired) in the component property inspector, on initialization through the
initObject of attachMovie(), or programmatically through
the respective property.
To simulate the smooth needle movement, this component updates the needle approximately
every 1/20th of a second (note: because it uses Flash's setInterval()
this interval can be up to twice as slow if the frame rate is set around 20
fps, due to "features" of the setInterval implementation). Therefore,
if you have more than a few of these components on the stage, you may find that
it slows down other processes. If you need many of these on the Stage at once,
you might consider rewriting this to centralize the needle update and need for
all the timers.
The component provides properties to bring in attached graphics based on movie
clip linkage ID's. This allows the developer to have multiple instances on the
Stage with different looks. Developers using the component FLA's can change
the appearance of the hand by modifying: defRndDialHand, center
of the dial by modifying: defRndDialCenter, the background graphic
by modifying: defRndDialBkgnd.
Showing the dial center and background are optional.
The suffix of variables recognized for codehinting purposes as FMXISRoundDialSmooth's
is _rdialSmooth.
