enhanced Draw Widget coordinate precision issue FV 3.0 Final

RhettZufelt — Thu, 28 Jun 2012 21:48:17 GMT

I am using the enhanced Draw Widget v 3.0 with FlexViewer 3 Final (uncompiled version).

I see the <numericlabelprecision> tag only modifies the number of decimal places for the right-click context menu. Is there a way to modify the number of decimal points for the "show measurements" option when a point is clicked?

Ideally, I would like the default 2 decimal places except when user selects Decimal Degrees. Then would like more than two to show up, but as is, that is all we get.

Sure, just use a NumberFormatter like this:

<mx:NumberFormatter id="numFormatterMeasure"
                            precision="2"
                            useThousandsSeparator="false"/>

And find out what the variable being populated by the measurement is, such as a function like this:

private function createLengthsLabel(length:Number, lengthAbbrev:String):String
            {
                return lengthLabel + " " + numFormatterMeasure.format(length) + " " + lengthAbbrev;
            }

Rhett,

Find the numFormatter and change the precision form 2 to numPrecision:

        <mx:NumberFormatter id="numFormatter"                             precision="{numPrecision}"                             useThousandsSeparator="true"/>

This will allow the numericlabelprecision to take affect on the number placed as text on the screen as well. As far as having it a different precision when using decimal degrees, you will have to make that code change with some simple logic that checks the units choosen.

Thanks guys, that got me on the right track. However, it brought up some strange behaviour that I will mention in a separate post.

Wasn't sure how to rate this as both were valuable info. Roberts was more specific to the edrawwiget.mxml so I marked his as the answer, but gave M a point...
