How can I add an MXML component as a child of the main application using ActionScript. It's not possible to instatiate it, is it? Assuming that behind every mxml file stands an actionscrpt3 class, I tried to import it but id didn't show up.
View 1 RepliesI've been trying to create a custom mxml component that extends another custom mxml component (i.e.MyMXMLComponent -> BaseMXMLComponent -> Group). I've been reading that trying to add visual children to MyMXMLComponent caused error with Flex 3 but that's no longer the case with Flex 4.
What I want to know is whether this is a supported/fixed/documented feature of Flex 4? or just some undefined behavior in Flex 4 that may get changed with future updates?
if this is supported and documented feature, does anyone have link pointing to adobe document stating it as such?
In our flex application we have tabs at the main level and under it we have subview.e.g
Home / Tasks / Admin etc...
In one condition we have to click on a button and open a new tab, on this tab we have to add an existing mxml component and show it in the tab.We are using parsley as the framework. Inside the mxml component test.mxml(that is shown in the tab) i am configuring it with parsley using the tag.Now when i add the instance of this test.mxml i am getting an exception. I am deriving this test.mxml instance using teh parsley context
as
context.getObject(id of component) as DisplayObject and adding it to the tabNavigator...
But i am getting exception when i try to grab an instance of a view using parsley context. How do i get an instance of a view or component that is configure through parsley using the parslye context.Also the problem is occuring becuase of the view injection..because i get a parsley excepiton on startup of the application stating that there is some problem in the context.
Are there any way to declare a child component in mxml which is private/protected or even static? Sure we can do this inside a script tag, but are there any other way?
View 2 RepliesHere is an example of a custom component. It is just a box with a title label and a close image (X):
[Code]...
When using the component in an MXML document, I would like to have the "(HEADING TEXT)" replaced with a parameter (should be easy) as well as the "(INSTANCE MXML)" with several labels, text inputs, check boxes, etc. (maybe harder). I have found this script-based method, but I would like a cleaner compile-time solution if one exists.
I have an event, which I have dispatched in my main.mxml:
var evt:UserEvent = new UserEvent(UserEvent.USERINFORMATION);
evt.userVO = storeObject;
this.dispatchEvent(evt);
I can listen for it while in my navigation.mxml file, by using
this.parentApplication.addEventListener(UserEvent.USERINFORMATION, onInfo);
But in other component, I can not listen for it, even trying the same as I did in navigation.mxml.
tracing it back gives me an undefined.
the second component is in a viewstack in navigation.
I would like to send variables or parameters from Component to Main (MXML) Application. Like my component is FileUpload.mxml and would like to forward the uploaded file details from FileUpload.mxml to Main.mxml.
I tried the following procedure :
com:FileUpload id="fp"
to get the reference for the FileUpload component, however, I am unable to get the variables from the FileUpload.mxml file.
I'm new to Flex and am porting a pure Flash/AS3 app to Flex 4.5. I've created a custom MXML component based on BorderContainer
<?xml version="1.0" encoding="utf-8"?>
<s:BorderContainer
xmlns:fx="http://ns.adobe.com/mxml/2009" [code]...........
and it would work well, but here in Flex 4.5 I don't know how to do this.Also I've noticed that there is a dropShadowVisible="true" attribute, but not sure if/how it can be used for my purposes.And I'm not sure if scaling up/down a custom component is allowed in flex or I probably should use "Flex Effects" (but how?) and also set disableLayout="true"?
In my main application I have a viewstack with 3 child views. In the viewstack change handler, I programmatically change the selectedchild property.
I understand that the initialize method for the view is not called every time I change the selectedChild Property. So I tried to invoke the init method programmatically too..

I am injecting two properties (question and answer) to the FaqItem component from an auxiliar file (using BabelFX) that depends on the id of the FaqItem, but it is only working when I choose the second option. If I use the first option, I get a child but with the text in question and answer fields is empty. I need to use the first option.

I have a checkbox in a component:
<s:CheckBox id="myCB_1" />
In my main.mxml I need to test for the state of the checkbox. I originally had all my code in main.mxml, but it was getting really long, and I thought that it was better practice to break my code into components. Also, I have other projects where the same concept will apply.I have the following function :
private function checkAlarms(currentTime:Date):void
{
if (!breakfastAlarmSounded)[code]....
doesn't work. Someone mentioned that I need to create a variable in my component that refers to the id (myCB_1) of checkbox, but I don't really understand or know how to do that, and they didn't elaborate.How do I test for the status of the CheckBox "myCB_1" in the component from within my main.mxml?
I am trying to override a Button class, i have a few properties which i wish directly initialise with the mxml description of the component, like :[code]which function is triggered ( in order to override it ) when all properties with mxml description is fully initialised with their values ?

I have two components. One is called "InsideComp" and one is called "OutsideComp". OutsideComp has InsideComp as one piece of its component, and in my main MXML file, I have embedded an instance of OutsideComp. How do I access a public variable of InsideComp within my main MXML file?In Actionscript, I could just do something like:OutsideComp.InsideComp.valToChange = 5; But I dont know how to do it in MXML. I know this is probably an easy question.
View 4 RepliesI have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
So I am loading in external swfs and once loaded in I want to stop the main timeline. so I do the following.
var swf : MovieClip = e.target.content ;
swf.stop();
which doesn't work, because I have trace statements in the external swf which fire off after that command is called. Which, here is another weird thing, When I trace through the loaded swf, it says it has two children, a shape, and a Loader. The shape is weird because what I have is another movieclip on stage so I should get instaceXX, and I dont know where that Loader class is coming from.
which also brings me to another question which is everytime I add the swf to the stage it duplicates the instance, and I run out of memory really fast after I keep removing and re-adding it. all I call is.
targetMC.addChild(swf);
then after the swf dispatches an event saying its done.
targetMC.removeChild(swf);

View 1 RepliesI'm working on a simple task/calendar tool where tasks can be added dynamically to a canvas. Here is the main application as defined in Main.mxml, which is essentially just a Canvas and a button for adding a task:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml">
<mx:Canvas id="MainCanvas" borderStyle="solid" width="300" height="300">
[Code].....
The problem is that when I add a Task instance to the Canvas, the children (the button and label) don't appear. I tried setting creationPolicy="all" on both the Canvas and the BorderContainer, but it still didn't work. I've read a bunch of posts about people having issues accessing members of their class before the class is fully loading, but all I want to do is SEE that Label and Button show up inside the BorderContainer.

How do I say an MXML component is inside some package? Well, it's in a different folder... I know how to do it ActionScript... But when I do in MXML I don't declare the package explicitly because I don't know how, and when I call it to my application, it states that The prefix "package" for element "package:Component" is not bound.
