ActionScript 3.0 :: Flex - How To Get Variables In Main MXML To Be Seen By Class
Nov 2, 2010
How can I get access to public variables in my main .mxml application from my AS class and vice versa? Also, say I have a main container panel defined in mxml, how can I reference to it's id from a separate class file?
i write a sound playback class that stop the older sound and play the new sound.After that i need an extra method in this class that trigger when the sound play is complete.I successfully achieve this, but i need to inform the main app (main.mxml) about the completion of that sound playing.
I have a initApp.as which instantiates a class which needs to access the "currentState" property and the States array as well. However we cannot get this to work as we cannot see how we can access this information.
Within initApp.as currentState is accessed via "this.currentState". This does not work in the class which is instatiated within initApp.as. The following error is thrown:
I'm building a Flex 4 Application in AIR.I've made a main.mxml and a login.mxml component. It all works but i can't communicate between my two mxmls (MAIN and COMPONENT)The login works but then it has to send a event tot the main that i can change the state in the main.Here is my cropped code.
login.mxml //resulthandler if login is succesfull loginUserResult.addEventListener(ResultEvent.RESULT, loginUserResultHandler);
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.
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 have the following problem of how to display another mxml file as main view of application For example, lets say I have main.mxml displaying as main window. When I click button I want to display another mxml file lets say newMain.mxml and close main.mxml
I have several mxml components in an app, all of which need the same variable called genericX. I've included that variable in the main mxml and made it public [Bindable] public var genericX:Number = 102; But I still can't access it from other mxml components. If I try to do this for example, it doesn't recognize the variable. <s:Button x="{genericX}" label="Click" />
I'm implementing a Flex application with several modules.I'm reusing the same component in all these modules.I was wondering if I'm correctly importing it in each mxml module definition: xmlns:hillelcoren="com.hillelcoren.components.*"Should I import it only once, in the main application mxml instead?
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 have a MC with a class attached to it, and I have other MCs within that MC. I need those MCs to be able to access variables within the main MC class. Here is a quick'n'dirty:
Code: class Foo extends MovieClip{private var h:Number; private var subMC:MovieClip;function Foo(_h:Number){h = _h;} subMC.onEnterFrame = function(){trace(h);}}
How can I access variables in the Foo class from another MCs scope? I have tried using static var but aren't they constant regardless of instance?
MyRenderer is a class that I wrote, but Flex doesn't see it and gives "defintion not found" error, because it is not within the mx namespace. What is a clean way to make this to work?
I have a page made of custom components. In that page I have a button. If I click the button I have to call another page (page.mxml consisting of custom components). Then click event handler is written in Action-script, in a separate file. How to make a object of an MXML class, in ActionScript? How to display the object (i.e. the page)?
I'm having a problem that has been really getting to me for the last 12 hours or so and I can't seem to find the answer anywhere. I know it's something simple, but I just don't know the correct syntax.
I've got a Flex Application in Flash Builder 4 with a file called "Test.mxml" which looks like this (simplified):
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 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:
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.
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 little problem in my game. I have a var coins:int = 0; on frame one, and I want to access it from frame 2. I'm not using a document class. Is it possible to make some kind of a global variable like in as2 without having to put all my code from the main timelime to a document 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]...
I have to make a project for school. It will be like a tutorial, but into an application. I already made a part of it in MXML and a bit of action script but I encountered a few problems that are over my newbie limits. So the Flex Builder 2 makes a SFW file, in the main folder of the "project". I want to make that SWF file my main executable file. I have a folder with some pics, and another folder with Action Script Files. The code lvl that I know atm is ABSOLUTE BEGINER... I don know how to make my SWF file have a specific name when I run it.Here is a picture of a training exercices that should make thing more clear:Some people told me that I should use a HexEditor and stuff. Is it ture(what u think?).
Next problem. I dont know how to make the Stage to be fix. I mean.. I dont want the stage to be resizeble. I tryed to change the stagescalemode but that wasn't it. I toke a look at the help files of Flex from the net, about the Resize action and SystemManegment, but I didn't find out what I wantend.
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?
Here is the case: Everytime that I clean eclipse project and restart Apcahe Tomcat server and run the application main MXML I got the following error "The requested resource (/{Main mxml file name}.html) is not available." To solve this everytime I should create a new MXML application,restart the server and then everything is fine.
I have extended an mxml component with an actionscript class. I'm trying to access a component in the mxml file using the id (in order to add an event listener) but I cant seem to do it.
I get:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I have some components declared in MXML tags, with some properties and event handlers.For some of them there is the need to re-instantiated, so I came up with the following architecture.Array of components that will be re-instanciated at some poin:
With MXML components, I've seen a pattern used where you have an AS3 class, then the MXML subclasses it, to have a separation between view/code (anonymized from real code):
package com.john { public class MyComponent extends Canvas {
[code]...
At least I think the MXML component is subclassing the AS3 class?Anyway is it possible/advised to do this with my main MXML application file, so I can put manager instances and things in the AS3 MyApp class, which is subclassed by Main.MXML?
