this is working fine cursor are blinking but not Highlighting the TextInput for focusing the TextInput. My All code is here:

In flex application how to get the ID of specific display component using mouse event. For example if I want to get the ID of a button it should be displayed when I click the button
do it with event.currentTarget.id like this :
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600">
<fx:Script>
<![CDATA[
import mx.controls.Alert;
protected function niceButton_clickHandler(event:MouseEvent):void
{
Alert.show(" the button id is: "+event.currentTarget.id)
}
]]>
</fx:Script>
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<s:HGroup width="100%" height="100%" verticalAlign="middle" horizontalAlign="center">

I am developing a desktop air application in flex. I have 2 mxml (one mxml is windowedapplication and another one in mxml group). I want to navigate from one mxml file (login.mxml) to another (nextpage.mxml).
How can I acheive this?
login.mxml:
<?xml version="1.0" encoding="utf-8"?><s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:s="library://ns.adobe.com/flex/spark" xmlns:mx="library://ns.adobe.com/flex/mx">
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<fx:Script>`enter code here`
<![CDATA[
public function onLogin()
{
// What code should i use to navigate to another mxml page i.e nextpage.mxml
}
]]>
</fx:Script><s:Button id="btn" name="Login" click="onLogin()"/</s:WindowedApplication>
nextpage.mxml:
<?xml version="1.0" encoding="utf-8"?><s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"

<s:Label text="Login Success/></s:Group>
It would be good to implement the main application as a coordinator of the application's state.
In this case you can use the ViewStack component, which has Login and NextPage components as children. The components communicate with the application by means of events. Depending on the current event the state is changed.
//Main app
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" xmlns:fld01="com.fld01.*">
<mx:ViewStack id="vsMain">
<s:NavigatorContent id="ncLogin">
<fld01:Login id="grLogin" evtLogin="{vsMain.selectedChild = ncNextPage}"/>
</s:NavigatorContent>
<s:NavigatorContent id="ncNextPage">
<fld01:Nextpage id="grNextPage" evtLogout="{vsMain.selectedChild = ncLogin}"/>
</s:NavigatorContent>
</mx:ViewStack>
</s:WindowedApplication>
//Login
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300">
<fx:Metadata>
[Event(name="evtLogin", type="flash.events.Event")]
</fx:Metadata>
<fx:Script>
<![CDATA[
public function onLogin():void
{
this.dispatchEvent(new Event("evtLogin"));
}
]]>
</fx:Script>
<s:Button id="btn" x="40" y="50" label="Login" click="onLogin()"/>
</s:Group>
//NextPage
<?xml version="1.0" encoding="utf-8"?>
<s:Group xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
width="400" height="300">
<fx:Metadata>

<s:Label x="40" y="50" text="Login Success"/>
<s:Button id="btn" x="40" y="80" label="Logout" click="onLogout()"/>
</s:Group>
I have an application width a mx:ViewStack component with differents view components under each s:NavigatorContent as it follows.
<mx:ViewStack id="vsOne" resizeToContent="true">
<s:NavigatorContent label="First">
<package:MyFirstComponent id="myFirstComponent"/>
</s:NavigatorContent>
<s:NavigatorContent label="Second">
<package:MySecondComponent id="mySecondComponent"/>
</s:NavigatorContent>
</mx:ViewStack>
And this is package.MyFirstComponent's important part..
<s:Button label="Next" click="somethingToGoForward()"/>
What I've tried:
Calling somethingToGoForward() in the view component and triyng to access to a parent vsOne: Don't work.
Calling parent.somethingToGoForward() (when this method is in the same mxml as the ViewStack): Don't work
How can I change my ViewStack's selectedIndex from anywhere outside the mxml file containing it?
Thanks.
This is an example using simple events:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" initialize="application1_initializeHandler(event)"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" xmlns:local="*">
<fx:Script>
<![CDATA[
import mx.events.FlexEvent;
protected function application1_initializeHandler(event:FlexEvent):void
{
viewStack.selectedChild=one;
}
protected function one_changeViewHandler(event:FlexEvent):void
{
viewStack.selectedChild=two;
}
protected function two_changeViewHandler(event:FlexEvent):void
{
viewStack.selectedChild=one;
}
]]>
</fx:Script>
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<mx:ViewStack id="viewStack" >

</local:ccomp>
<local:ccomp id="two" changeView="two_changeViewHandler(event)" text="LAbel TWO" >
</local:ccomp>
</mx:ViewStack>
</s:Application>
ccomp is a custom component
<?xml version="1.0" encoding="utf-8"?>
<mx:HBox xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx" width="400" height="300">

I got very basic question. Why this is not working?!
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
width="1000" height="550" minWidth="960" backgroundColor="#F2F0F0">
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<s:Label id="test1" x="43" y="259" text="Label"/>
<fx:Script>
<![CDATA[
test1.text = "Yay! This works...!";
]]>
</fx:Script>
</s:Application>
I got this error: Access of undefined property.
Thanks!
You're setting the text before the component is created. Try putting the assignment into a method and calling the method on creationComplete:
<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"
width="1000" height="550" minWidth="960" backgroundColor="#F2F0F0"
creationComplete="onCreationComplete()">
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
</fx:Declarations>
<s:Label id="test1" x="43" y="259" text="Label"/>
<fx:Script>
<![CDATA[
public function onCreationComplete():void {
test1.text = "Yay! This works...!";
}
]]>
</fx:Script>
</s:Application>
using flex, is it possible to make a square, drawn using s:rect , clickable?
I am trying to draw a series of coloured boxes and allow them to be clicked on to perform an action.
I wasn't able to target it directly so I wrapped it in a BorderContainer and that did the trick. Or you could just use a BorderContainer if all you want is a box you can color and target.

myBox.addEventListener(MouseEvent.MOUSE_OVER, changeColor);
