I have several components where I want to enable buttons based on passing a username to a function. I want to dynamically bind the "enabled" property on a button so that if the "somethingChanged" event fires, a button may become enabled or disabled. But, I'm not sure where to fire the "somethingChanged" event. It's possible that I may need to fire the "somethingChanged" event from several places in the application. Is this possible with a bound static function?
EventManager.as
public class EventManager():void {
[Bindable(event="somethingChanged")]
public static function hasAccess(myVal:String):Boolean {
}}
[Code] .....
I would like to bind two components with out binding and which resides in different MXML.for eg: A.mxml has textinput and B.mxml has a combobox when choose one item in B.mxml selected item should be display in A.mxml textinput.
I would like to display an empty string in the button's label until the locale file loads. Once the locale file loads I would like to display what is returned by getLocaleString('title').
I think that this is what Binding is intended for however I think that I am approaching it wrong.
I know that I am not allowed to bind on a function. So do I need to allow access (using a get function) to my _dictionary property? What is the standard way to setup Binding for something like this?
This is my current Locale class.
public class Locale { private static var _dictionary:Dictionary = new Dictionary(); public static function loadResources():void {...}
But I get a warning from Flex that the binding wouldn't work that way and it doesn't. It works the first time I load up the component but every time I change findFriendsPaginationElement it doesn't reflect on the component. Do you know how I can go about doing this? (making changing a value in the binding variable changes the status of an element inside a component?)
i'm using flash builder 4..i want to ask something..how to binding data to custom list component in flex??...i already try binding data from webservice to standard datagrid component in flex, and it's work perfectly...this is my code for binding to datagrid..
I have a main mxml file (flex4) and want to pass a parameter (user_name) to a component in a directory called components. When I run the program, the user_name is NOT being sent from the main to the component file. (Interestingly, if you make the component visible, you can see the parameter has been passed).
I have hacked much larger files down to get the following two files: Main <?xml version="1.0" encoding="utf-8"?> <s:Application xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600" [Code] .....
I'm having a problem in flex 3 where if a static const I have defined is used as the parameter to a function call within binding tags I get a "1120: Access of undefined property NodePropertyMatrix". _propMtx is a ArrayCollection.
Lately i discovered MATE (for Flex development) and was wondering: how do i bind a property in a view (actually a navigatorcontent component) to another property in a class so that they stay in synchronization (meaning that whenever the property in the class changes the property in the view also changes).
So if we have a view called Target.mxml and a property targertProp how do we bind it to the class called SourceClass with property SourceProp?
What I have is a class with static properties that I want to use as images. I would like the images to be configurable at run time but still have the defaults. So the Images class looks like:
[Code]...
Clicking the button will change the static property in the Images class to something else. The image defined in the MXML will get the binding event and update the image, but the custom component created in ActionSctipt will not be updated.
Let's say I have a Custom Event Class, and it has several Event types stored in static Constant:
[Code]...
Is there an easy way to validate that the type passed to the Constructor is one of the Static Constants of the Class, without having to check it against each value?
I know that one can give a symbol already placed in the scene and instance name and be able to manipulate that object programatically through ActionScript in Frame actions. What I want to do instead, is bind that instance name to a class member so I can use it inside a class file and and eliminate the need for frame scripting.
I am new at this and I'm trying really hard to figure out what the ideal workflow is. I would like to use a fully OOP approach at developing my applications, however I like to use the graphical interface to position assets on the scene because I find it easier than positioning assets programatically. So the solution I am looking for is binding assets to class members. If such a workflow is not possible, what's the best approach in dealing with assets in a fully OOP design?
I'm a complete Flex/Flash noob, running Adobe Flash Builder 4 Beta 2. I have a main component that needs to be able to call several popups, each mostly the same except for one function and a few labels. Obviously, I'd prefer to be able to define this function and change those labels when calling the popup instead of having tons of .mxml files with nearly the same code, I just don't know how to do it. I figured out how I can change the labels, but not sure how to redefine the function.For simplicity's sake, let's say my code looks like this:
How do I get "close" button to run runFunction() from within component to outside declaration? FxGlobals.topLevelApplication doesn't seem to be working for this.
Our software team has been developing flash applications using AS3 (via the FlashDevelop IDE and the free Flex SDK). Recently, some members of the team started exploring FlexBuilder and Flex (wow... why did we wait so long?). The problem is that some folks continue to develop using pure Action Script 3 (FlashDevelop) while others are creating custom components in FlexBuilder. How do the AS3 developers use the Flex Custom components built in FlexBuilder in their AS3 Applications?
I'm new to AS3, and can't figure out why this loop isn't behaving the way it "should."
[Code]...
How can I give each anonymous function a reference to each object represented by f, rather than a simple reference to f each time? Specifically, why is it that each copy of the anonymous function gets bound to a single reference to f? How (I should say why) exactly does AS3 differ from JavaScript in this regard?
I will need to execute a function in a comp1.mxml from main.mxml through event, I found it difficulty to understand and unable to get it work.[code]...
Is is possible to bind class properties to mxml components ? E.g.: I have a class A.as with a String property nameValue. What I want to achieve is always having the latest value of a mx:Text component in nameValue.
I'm trying to set the height of a vertical bar (activityBar) but it does not appear to do anything. i have tried something similar with the whole component, but setting the dimensions does nothing (even in the mxml used to instantiate the class). Indeed, I've added transparent graphics just to give the component some dimensions
FYI: I'm trying to create a mic activity bar that will respond to the mic by simply setting the height of the activityBar child (which seems to me to be more efficient than redrawing the graphics each time).
package components { import mx.core.UIComponent; public class MicActivityBar extends UIComponent { public var activityBar:UIComponent;
Is it possible to access a declared component as an IFactory within an MXML class? I've used this style of declaring factories many times for Skin Parts, but I've never figured out how to access those factories from within the MXML.
I have a singleton class that looks something roughly like this (only with more bindable public properties):
public class Session extends EventDispatcher { private var _Id:String; private static const _instance:Session = new Session( SingletonLock ); private static const SESSID_CHANGED:String = 'SessionIdChanged';
[Code]...
The abnormal behavior I'm discovering is that the event listeners registered through registerOnSessionChange are indeed being called when the session Id changes, but the MXML data binding expression is not updating. I've tried all combinations of dispatching the event during the capture phase, and making it not cancelable, but to no avail. My understanding of [Bindable (event= ...)] is that the MXML should update the url string when the event specified is dispatched, so what am I doing wrong or misunderstanding?
Note: I realize there are lots of different ways of doing the singleton pattern in Actionscript, but unless the way I am doing it is actually causing my problem somehow,
I'm trying to do this using only mxml, no <script> tags, although I don't necessarily need a solution that's only mxml. It was more of an educational exercise to see if I could do it all in mxml. I have a custom component that has a slider and textinput and their value/text properties are bound together. I'm surfacing a few properties of the slider in my component so that it can sort of be treated like a slider.
How do I call a custom component's public function from the main app. For example, I've got a timer component, MyTimer.In the main app, I want to call startTimer() or stopTimer().In the main app, I've got:
<visualcomponent:MyTimer /> In the component, I've got: public function startTimer():void {
I hope I have worded the question ok. I know that you can pass the 'id' of the component but I'm just wondering if there is a more generic way. I have tried using 'this' (shown in example below) but the 'this' keyword refers to the application.
I would like to know if it is the same to assign properties to my custom component in its own class, or from the parent document. Here I assign the property bottom in my custom component class:
I was wondering how I apply an edited actionscript class to a component?
I've made a few changes to the TileLayout class (spark.layout.supportClasses.LayoutBase), but am unable to apply this new layout format to my group in my application... is it treated like a different tag within the layout tag?[code]...
