Using the (… args) Operator.

The usage is so simple and clear. Using this operator we can pass n number of variables values and hold them for calculation.The variable can be of any type and the final args contains the array of elements we pass.the below example will make you clear.

Flex Code Example:

CreationComplete=”init()” –>Call this on Application creation.

scrpt Code

private function init():void
{
lbl.text=String(average(100,100,100,100,100));
}
private function average(… args):Number
{
var sum:Number=0;
var i:int;
for(i=0;i<args.length;i++)
{
sum+=args[i];
}
return sum/args.length;
}

MXML code

<mx:Label id=”lbl” />

Enjoy the Post and Operator. Make your code simple.

Tooltip for DataGrid Column Elements.

Here itemRenderer comes into play.The below code will given on idea how this is achevied but you need to go through the Classes.

Flex App.mxml code

<?xml version=”1.0″ encoding=”utf-8″?>
<mx:TitleWindow xmlns:mx=”http://www.adobe.com/2006/mxml” layout=”absolute” width=”700″ height=”300″
creationComplete=”projectsSrv.send();”>
<mx:HTTPService
id=”projectsSrv”
url=”projects.php.xml”
useProxy=”false” method=”POST”>
</mx:HTTPService>
<mx:DataGrid  dataProvider=”{projectsSrv.lastResult.records.record}” width=”370″ x=”23″ y=”10″>
<mx:columns>
<mx:DataGridColumn dataField=”label”>
<mx:itemRenderer>
<mx:Component>
<mx:Label>
<mx:Script>
<![CDATA[
override public function set data(value:Object):void
{
super.data = value;
this.toolTip = data.label;
this.selectable = true;
super.invalidateDisplayList();
}
]]>
</mx:Script>
</mx:Label>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
</mx:columns>
</mx:DataGrid>
</mx:TitleWindow>

projects.php.xml code.

<records>
<record data=”1″ label=”Corco”/>
<record data=”5″ label=”Shell Crop Protection”/>
<record data=”7″ label=”Olin McIntosh”/>
<record data=”9″ label=”Crab Orchard”/>
<record data=”10″ label=”Shell Oil Del Amo”/>
<record data=”11″ label=”AIG South Jersey Gas”/>
<record data=”12″ label=”Husch &amp; Eppenberger Litigation-New York”/>
<record data=”22″ label=”Shell Sturbridge”/><record data=”24″ label=”Shell Southington”/>

How to Print contents of a Container (Canvas) ?

Here iam having two Two containers (canvas) with my data in it and now I want to print the contents of the canvas as a whole.

Two containers [canvas] à PrintPreviewL,PrintPreviewR
Now I want to print the contents of these containers.

The function which does the print is :

public function doPrint():void
{
// Create a FlexPrintJob instance.
var printJob:FlexPrintJob = new FlexPrintJob();

// Start the print job.
if(printJob.start()) {
// Create a PrintView control as a child
// of the current view.
var formPrintViewL:PrintPreviewL = new PrintPreviewL ();
var formPrintViewR: PrintPreviewR = new PrintPreviewR();
addChild(formPrintViewL);
addChild(formPrintViewR);
// Add the SimplePrintview control to the print job.
// For comparison, try setting the
// second parameter to “none”.
printJob.addObject(formPrintViewL);
printJob.addObject(formPrintViewR);
// Send the job to the printer.
printJob.send();

// Remove the print-specific control to free memory.
removeChild(formPrintView);
removeChild(formPrintViewT);
}

}

This will print the contents of the two canvas in sequence as we send to the printJob.As you can see.

Can go through the classes to learn the Basics and start. All the Best.

Enjoy the code ! , leave me comments for queries.

Using NumberFormatter !

This class is used to format the number in a way we like, like the number 2000 to 2,000 or 2000 to 2,00.00 or 2000.2345 to 2,000.23 like that.So the usage is given below, its like the beautification to the data.

Code Example:

<mx:NumberFormattter id=”nftr” precision=”2″ />

Now in a the Script block u can use this to format the number.As

nftr.format(2000.123456);

This will format to 2,000.12.

There are still many properties in the NumberFormatter class to use like thousandSeperatorfrom,thousandSeperatorto …… like so, can explore these very simple.

As i said it addds beautification to the data in the Application.

Enjoy the post.Can leave a comment for queries.
