The NumericStepper component in Flash 8 seems to have a problem. Where
minimum = 1, maximum = 10, stepSize = 2, value = 1, the second value on
clicking the up arrow is 2. Then it is changing to 4 > 6 > 8 > 10. What
I expect is 1 > 3 > 5 > 7 > 9 > 10.
Therefore, I modified NumericStepper.checkValidValue() method as
follows. To test the script just place the NumericStepper component
into the [Library] without anything on the stage.
Any comments and suggestions for this modification would be very
appreciated.
// dynamically placing a NumericStepper instance
import mx.managers.DepthManager;
import mx.controls.NumericStepper;
var myNumericStepper:NumericStepper =
this.createClassChildAtDepth(NumericStepper, DepthManager.kTop);
// initializing
myNumericStepper.move(10, 10);
myNumericStepper.minimum = 1;
myNumericStepper.maximum = 10;
myNumericStepper.stepSize = 2;
myNumericStepper.value = myNumericStepper.minimum;
// modifying NumericStepper.checkValidValue() method
NumericStepper.prototype.checkValidValue = function(val:Number):Number {
// var initDiv:Number = val/this.stepSize;
// var roundD:Number = Math.floor(initDiv);
var stepS:Number = this.stepSize;
var minVal:Number = this.minimum;
var maxVal:Number = this.maximum;
var initDiv:Number = (val-minVal)/this.stepSize+minVal;
var roundD:Number = Math.floor(initDiv-minVal)+minVal;
// if (val>minVal and val<maxVal) {
if (val>minVal && val<maxVal) {
if (initDiv-roundD == 0) {
return val;
} else {
// var tmpV:Number = Math.floor(val/stepS);
var tmpV:Number = Math.floor((val-minVal)/stepS);
var stepDownV:Number = tmpV*stepS+minVal;
if ((val-stepDownV>=stepS/2 && maxVal>=stepDownV+stepS
&&
minVal<=stepDownV-stepS) || (val+stepS == maxVal &&
maxVal-stepDownV-stepS>0.00000000000001)) {
stepDownV += stepS;
}
return stepDownV;
}
} else {
if (val>=maxVal) {
return maxVal;
} else {
return minVal;
}
}
};
