RE: [flexcoders] Re: How do I convert an object to an arrayCollection?

[Alex Harui]

I don't know anything about fluorine, but based on the object, I'd
programmatically set up the DG

 

All the formatting got lost in the email, so I might be off a bit, but
I'd do something like this:

 

var fieldMap:Object = new Object();

var cols:Array = new Array();

var n:int = columnNames.length;

var i:int;

for (i = 0; i < n; i++)

{

            // map filed names to array indices

            fieldMap[columnNames[i]] = i.toString();

            var dgc:DataGridColumn = new DataGridColumn();

            dgc.headerText = columnNames[i];

            dgc.dataField = i.toString();

            cols.push(dgc);

}

grdPERSONResults.columns = cols;

grdPERSONResults.dataProvider = initialData;

 

You can access the fields of the data objects like this:

 

trace(initialData[i][fieldMap["PERSON_NUMBER"]);

 

If you do that, you can handle any result type.

 

If you know the fields you are going to get, you can use a similar loop
to convert to object.  Declare a class:

 

Class PERSON

{

            Public var PERSON_NUMBER:int;

            Public var PERSON_NAME:String;

            ...

}

 

var n:int = columnNames.length;

 

Var persons:Array = new Array;

var m:int = initialData.length;

for (i = 0; i < m; i++)

{

            Var person:Person = new PERSON();

            For (var j:int = 0; j < n; j++)

            {

                        person[columnNames[j]] = initialData[i][j];

            }

}

 

grdPERSONResults.dataProivder = persons;

Yes you can, but this does not allow the ability to access the fields 
in the data provider by name. 

In my existing programs I might have something like;

================================================================
<mx:DataGrid x="10" y="64" width="599" height="424" 
id="grdPERSONResults"
itemClick="grdPERSONSelected(event);" >
<mx:columns>
<mx:DataGridColumn headerText="Number" textAlign="right" 
width="60" dataField="PERSON_NUMBER"/>
<mx:DataGridColumn headerText="Name" width="200" 
dataField="PERSON_NAME"/>
<mx:DataGridColumn headerText="Original #" textAlign="right" 
width="65" dataField="PERSON_ORIG_NUMBER"/>
<mx:DataGridColumn headerText="SSN" labelFunction="SSNFormat" 
width="85" dataField="PERSON_SSN"/>
<mx:DataGridColumn headerText="Date" labelFunction="showDate" 
textAlign="center" width="80" dataField="PERSON_DATE"/>
<mx:DataGridColumn headerText="Status" textAlign="center" 
width="50" dataField="PERSON_PERSON_STATUS"/>
</mx:columns>
</mx:DataGrid>
================================================================

And I would like to convert it to Fluorine with as little change as 
possible.
