Conversion of temperature from kelvin to Celsius:
It is a very famous example and almost everyone of us have done this example once in any language. So let's see how to do this conversion in flex. We'll come to know how to convert using different GUI of flex. Also in this tutorial we'll see how to put the mxml and action script section in separate
files, and how to access the action script file from mxml file.
temperature.mxml
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" >
<mx:Script source="temperature.as"/>
<mx:Panel title="Convert Temperature" paddingBottom="10" paddingTop="10" paddingLeft="10" paddingRight="10" x="138" y="44">
<mx:HBox>
<mx:Label text="Farenheit" id="f"/>
<mx:TextInput id="far"/>
<mx:Button id="button" label="convert" click="convert()"/>
<mx:TextInput id="cel"/>
</mx:HBox>
</mx:Panel>
</mx:Application>
temperature.as
public function convert():void
{
var f:Number=Number(far.text);
var c:Number=Number(cel.text);
c=Math.round((f-32)/1.8*10)/10;
cel.text=String(c);
}
