Data Binding with Components

Definition:

It is used to tie data in one object to another. That is, it is used to pass data

between different layers of the application. There are three ways to use

DataBinding. They are,

1. {} syntax

2. <mx:Binding> tag

3. BindingUtils static methods

The requirements for this DataBinding are source property, destination

property & an event.

Source Code:

<?xml version=”1.0″ encoding=”utf-8″?>

<mx:Application xmlns:mx=”http://www.adobe.com/2006/mxml”

layout=”absolute”>

<mx:TextInput id=”myText”  x=”315″ y=”251″/>

<mx:Label text=”{myText.text}” x=”315″ y=”294″/>

</mx:Application>

Creating ToolTip

Definition:

All visual components that extend the UI component class support a tool tip

property.  When a mouse pointer hovers over the component, the string

appears in the tool tip.

Source Code:

<?xml version=”1.0″ encoding=”utf-8″?>

<mx:Application xmlns:mx=”http://www.adobe.com/2006/mxml”

creationComplete=”initApp()”  layout=”absolute”>

<mx:Script>
 
<![CDATA[
 
import mx.controls.TextInput;
 
public function initApp():void
 
{
  
var myTextInput:TextInput = new TextInput();
 
myTextInput.toolTip = ” This is a TextInput Control”;
  
addChild(myTextInput);
 
}
 
]]>

</mx:Script>

 

</mx:Application>
