I'm trying to come up with the optimal solution for validating IP addresses in Adobe Flex. My current solution is to use a regexp validator and look for dotted quad numbers, see code below. For some reason this will also allow an address like "1.2.3.4.5". Does anyone have a better solution out there?
<?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;
]]>
</fx:Script>
<fx:Declarations>
<!-- Place non-visual elements (e.g., services, value objects) here -->
<mx:RegExpValidator source="{ipAddr}" property="text"
expression="\d+\.\d+\.\d+\.\d+"
invalid="Alert.show('The IP address is invalid');"/>
</fx:Declarations>
<s:TextInput id="ipAddr" x="10" y="10"/>
<s:Button label="OK" x="10" y="40"/>
</s:Application>
Regexp to validate an IP is the following:
var regexp:RegExp = /^(([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])\.){3}([0-9]|[1-9][0-9]|1[0-9]{2}|2[0-4][0-9]|25[0-5])$/;
trace(regexp.test("10.0.0.5")); // true
trace(regexp.test("243.1.254.15")); // true
trace(regexp.test("256.0.0.0")); // false
Hope that helps
You could split("\\.") the string, check that the resulting array has a length of either 4 or 6, and that each element is an integer between 0 and 255

how to I pass in a uicomponent to a mxml custom component?
ex: I want to pass in any number of buttons, and I want my custom component to lay them out in a certain order.
MainApp.mxml:
<?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" xmlns:local="*"
>
<local:myComp >
<s:Button label='Button1' />
<s:Button label='Button2' />
<!--I want to add anything else here -->
</local:myComp>
myComp.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"
xmlns:mx="library://ns.adobe.com/flex/mx"
creationComplete="init()"
width="400" height="300"
>
<fx:Script>
<![CDATA[
private function init():void {
// how do I access the added components and place them where I want?
// do I use removeChildren and AddChildren?
// addItemsHere.addchild(nextButton);
]]>
</fx:Script>
<s:HGroup id='addItemsHere' />
As your component extends Group, you shall use addElement instead of addChild (and for all other methods with 'child' in their name it shall be replaced with 'element'. So, access to all elements will be like that:
for(var i:int =0; i < numElements; i++){
var button:Button = Button(getElementAt(i));
doWhatIWantWithMyButton(button);
}
It is also better to override createChildren method of your component if you know what to add at the creation moment.
If you don't need very specific button placement, you can set layout property of your component to any desired layout (like VerticalLayout, for example), and those layouts are tunable.
You seem to be trying to recreate functionality that already exists in the SDK. This is wat SkinnableContainer is for.
Depending on your use case, there are two ways to use it:
You only need to add some custom graphic elements to you custom component, but no additional behaviour
In this scenario, you would simple reuse SkinnableContainer and assign it a custom skin, like so:
<s:SkinnableContainer skinClass="MySkin">
<s:Button label='Button1' />
<s:Button label='Button2' />
</s:SkinnableContainer>
With MySkin.mxml perhaps something like:
<s:Skin xmlns:fx="http://ns.adobe.com/mxml/2009"
xmlns:s="library://ns.adobe.com/flex/spark">
<fx:Metadata>
[HostComponent("spark.components.SkinnableContainer")]
</fx:Metadata>
<s:states>
<s:State name="normal" />
<s:State name="disabled" />
</s:states>
<s:layout>
<s:VerticalLayout/>
</s:layout>
<s:Label text="I'm a SkinnableContainer"/>
<s:Group id="contentGroup" width="100%" height="100%">
</s:SkinnableContainer>
Your Buttons will now automatically be added to the contentGroup; the SkinnableContainer class handles this for you. Note that this Group must have exactly that id; it's a required SkinPart.
You want to add some behaviour to you component
The procedure is the same, but you would now subclass SkinnableContainer (this is usually done in pure ActionScript), write some behaviour in there, and assign the skin to an instance of this class.
public class MyComp extends SkinnableContainer {
//additional behaviour goes here
}
Usage:
<local:MyComp skinClass="MySkin">
<s:Button label='Button1' />
<s:Button label='Button2' />
</local:MyComp>
I am new to flex and I am trying to open modules in a new window modal.
I have managed to load and add a module in a container ( vbox ) but what I really need is to open them in separate windows.
All posts that I could find are samples on how to load modules but nothing on how to show them.
I found a post here
Modules and Panels issue
and it looks by the screenshot exactly what I am looking for.
Thanks for your help.
I found a way of doing this.
Thanks for all the pointers
here is how I did it for all of you to see and maybe use. If you have suggestions to make it better, do not hesitate to comment.

I'm making simple editor. And I want that, let write replacing colorless text to color text from RichEditableText when I will write any text.
For example:
PHP --> <s:span color="#FF0000">PHP<s:span>
This codes not work:
editorum.text = editorum.text.replace('PHP','<s:span color="#FF0000">php<s:span>');
Editorum is: <s:RichEditableText id="editorum" ></s:RichEditableText>

A other problem; How do I send the pointer at the end? When I press any key, pointer going to deal. Try: http://samed.us/samples/ops3.swf
Thanks for your help...
Instead of this line:
editorum.text = editorum.text.replace('melon','<s:span color="#FF0000">melon<s:span>');
Try something like this:
var text : String = editorum.text.replace('melon','<s:span color="#FF0000">melon<s:span>')
editorum.textFlow = TextConverter.importToFlow(text, TextConverter.TEXT_FIELD_HTML_FORMAT);
Basically, you need to convert the HTML into something that the TLF Framework will understand. Read some docs on textFlow and the TextConverter
I'm trying to scale text from 1 to 5, a sort of zoom in type of look. I'm using the code below:
<s:Scale target="myLabel" autoCenterTransform="true"
duration="2000"
scaleYFrom="1" scaleYTo="5" scaleXFrom="1" scaleXTo="5"
>
The text scales terribly. So my goal is to take a snapshot of the text label at a large font, add it to the display list, set the scale to a 5th and then animate the scale up to 1. After that I have to set the text again and do it all over again.
This is a Flex app and that's where my question comes in. I don't know how to take a snapshot, then what to add it to (group?) and then how to erase it and start over again? Any advice in any of this would be appreciated.
Here's a very simple approach which animates the fontSize style, instead of animating the scale properties:
Depending on what you're doing this may not perform well b/c it is setting a new style so frequently. Also, if you play this animation slowly, it looks like the individual characters "wobble" (they move or shake a teeny bit).
I'll post something on taking a snapshot and scaling that next...
<?xml version="1.0" encoding="utf-8"?>

<fx:Declarations>
<s:Animate id="scaler" target="{scaledText}" >
<s:MotionPath property="fontSize">
<s:Keyframe time="0" value="12"/>
<s:Keyframe time="1500" value="48"/>
</s:MotionPath>
</s:Animate>

protected function onLabelClick():void
{
scaler.play();
}
]]>
</fx:Script>
<s:Label id="scaledText" text="this is some text" click="onLabelClick()" />
</s:Application>
And here is the approach that takes a snapshot of the text. This has the same problem as your original solution, the scaled text is very jagged. But this does show how to take a snapshot of something and use the snapshot in another Flex object:
<?xml version="1.0" encoding="utf-8"?>

g.beginBitmapFill(data);
g.drawRect(0,0, 200,200);
g.endFill();
}

When i am checking the above sample code in IE Browser its working fine, But its not working in Mozilla and Chrome browsers.
What could be the Problem ? How can i able to display this in other browsers? Can anyone help on this?
Thanks in Advance
Rajesh
Have you tried url encoding your String in Javascript then decodinf in AS?
For e.g.:
Javascript:
flashvars.sampleText = escape("String with special characters");
AS/MXML:
<s:Label text="{unescape(FlexGlobals.topLevelApplication.parameters.sampleText)}" />
Hope it helps,
Rob
