Flex current target property example
The example below describes the working flex currentTarget property. Code below shows a method
.setSelection which is used to highlight
the text letters as per defined closed indexes. Here, use of <![CDATA ---
]]> is optional. In the code, two functions are defined, viz.,
protocol
and virus; both are event handler functions. First method defines the
Label control id and puts data in to core.text, where
text is the attribute defined in TextInput
control and the second function highlights the
text characters from index 5 to 20 in TextInput. Both are click based
event functions, however the protocol function gets initialized first because it
is passed in the initialize attribute of the root tag. Root tag is coded
as <Application/>, and is called as the root tag of the
application inside which other flex control and container
tags are coded.
currentTarget.mxml
<?xml version = '1.0'?>
<mx:Application xmlns:mx = 'http://www.adobe.com/2006/mxml'>
<mx:Script>
<![CDATA[
public function protocol(event:Event):void{
master.text = 'Label' + event.currentTarget.id + 'is clicked';
core.text =
'Weaving = Agent Smith said that in an interview about Matrix Reloaded';
}
public function virus(event:Event):void{
TextInput(event.currentTarget).setSelection(5,20);
}
]]>
</mx:Script>
<mx:TextInput id = 'core' text = 'click on me' click = 'virus(event);' />
<mx:Label id = 'master' click = 'protocol(event);'/>
</mx:Application>
