i want to call an external function inside a class. thats the code;
in checkConnectionStatus function,
this[_funcNameForSucceededCon].apply(); doesnt work because "this" is the class, not the Application. How can i reach Application at this time or what can i do?
package myLibrary
{
import air.net.URLMonitor;
import flash.events.Event;

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 know there are ways to invoke javascript inside the html wrapper template for the flex application using ExternalInterface, but is it possible to reference an external html page?
View 3 RepliesI have a main application that contains a list, using a custom itemRenderer to display data.
I would like to be able to call a function, inside the itemRenderer, from the main application.
When running the app, we have a list with three persons, and a button. I want to call the function myItemRendererFunction() inside the itemRenderer, of the selected item in the list, all this, from the main app.

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.

I have an AS3 program that calls a function multiple times. The function must return multiple variables, so I created a class for the function to declare an object containing all of these variables. For example, here's my class:
package
{
public class PER
{
[Code].....
Let's say the calling program calls the function, which returns the variables into data_set1 (where data_set1 depends on input variables arg1, arg2, arg3) using:
var data_set1:PER = function_name(arg1, arg2, arg3);
The calling program does some stuff, then calls the function again, but returns the variables into a new variable name, data_set2:
var data_set2:PER = function_name(arg4, arg5, arg6);
My intention is that data_set1 and data_set2 are different (e.g. not linked together).
My question is, given that arrays are passed by reference, will data_set1 be modified to agree with data_set2 upon the 2nd function call? Why or why not?
Does anyone know if there is a way to call a dispatchEvent call from inside of a static function?
View 2 RepliesI'm trying to organise my code better and figured it would be good to place the pop-up logic within the component that's being popped-up. However, I can't seem to do this without causing one error or another. I also need to make the pop-up modal.I'm doing something along these lines (psuedo code):
<mx:TitleWindow >
<mx:Label id="messageLabel" />
<mx:Script>

I am creating a custom component in Flex with extends the BorderContainer class, and I would like to be able to place additional content within the tagset when I use it in my main application, like this:
<components:CustomComponent title="Hello">
<s:Label text="If you have one enter it below:"/>
<mx:Spacer height="15" />
[Code]....
This works just fine, except that my component definition had some additional things inside of it, such as a <s:Label/> and styling, which is replaced by the content within the tagset above when I go to use it.
If I do not put anything within the tagset, the content that was originally in the component is not replaced.
Is there a way that I can simply append additional content inside of the component when I go to use it, instead of it being replaced each time?
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.
View 2 RepliesI'm using Flex with Cairngorm framework.I have a custom component which I create like this:
<components:FriendSearchPaginator id="searchResultsPaginator"
paginationElement="{_model.findFriendsPaginationElement}"
visible="{_model.friendsSearchResultsPaginatorVisible}" />
Where the findFriendsPaginationElement is inside the model locator:
public var
[Bindable]
findFriendsPaginationElement:PaginationElement = new PaginationElement();
Inside the custom component I have button that uses a property of findFriendsPaginationElement object:
<s:Button id="previousButton"
label=" prev "
click="paginateSearchResults(false)"
enabled="{_model.findFriendsPaginationElement.more_previous}"/>
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've developed a component which is a combination of a few items (canvas, labels, etc...) but when I try to bind it to a variable such as: {stationXML.getItemAt(1).AAA.@value}, it doesnt work. Before I combined all the items in a component, they were all in the main MXML file at which time they worked. Not sure if it matters, but the "stationXML" arraycollection variable is declared inside the file "Station.as".
View 2 RepliesI've created a custom component based on Image component. I want to teach it to respond to change of binded variable. E.g. if main class has a variable balance, I want the component to change image in case balance = 100 one image, in case balance = 50 to another.[code]...
View 1 RepliesI googled for almost a day to find the answer to my question: [URL]. This almost works (and is a great solution), but the solution doesn't work when I do:
1). Copy and paste multiple-line texts.
2). Write long and scroll the texts.
I also found another working example at: [URL]. (The autocomplete prompt appears when you press ctrl+space right at the caret's position). But an email from its author says he uses monotype fonts to calculate individual character's location. Is there a way to get multi-line input from a textfield?
I have the following component in an AIR application from Flex 4:
<mx:HTML id="viewObject"
x="10" y="42" width="634" height="313"
location="http;//localhost:8080/mypage.php" />
Now I want to run a javascript when the page loads but the javascript isn't inside the target page. I want to run the following javascript:
javascript:alert('Hello world.');
I tried approaching it by setting the location property again to the javascript after the page has loaded like below.
<s:Button x="10" y="10" label="Button">
<s:click>

Unfortunately for me, that doesn't seem to work.
why I can't get the width of a Sprite when it has components in it.
For example
Code:
var foo:Sprite = new Sprite();
addChild(foo);
var comboBox:ComboBox = new ComboBox();
[Code]....
I'm assuming the component possibly isn't set before I'm trying to get the width?
I have a swf file sample.swf which has its actionscript class in Main.as. This Main.as has various objects declared as public in it. For instance lets consider an object myData of class MyData (in MyData.as).
I am loading this swf file in my AIR app using swfLoader. I want to know how do I access myData.func() using swfLoader.loaderInfo.content.
I have a component that I hand over a function
public var func : Function;
Now the function is a function that has parameters in its signature
public function myFunction(s : String) : void {
doSomething(s);
}
from my component I can call the function with
func.call();
how to invoke the function with its parameters?
How can I set a function to be called when the length of a DataProvider changes?

So, I create standard AS3 flex project. In constructor goes only start();
rest of functions are basically this:
private start():void { f1();}
private function f1():void { f2();}
private function f2():void { f1();}
And it's standard recursion. SWF either breaks or loops as many times as I tell it. One f calls the other, which calls first... I do not want that.
I want f1 to do some stuff, calls f1 and closes itself. Than f2 works, calls f1 and closes. And so on.
Like having 2 sets of code that loops through.
What's the cleanest way to do that?

I have a Flex 3.4 app that embeds a swf with mx:SwfLoader...
That swf has a public function named "playIt". I've tried dispatching events to gettingHere.content, casting gettingHere.content as a MovieClip and other stuff...
var swfApp:MovieClip = MovieClip(gettingHere.content);
if (swfApp.hasOwnProperty("playIt")) {
var helloWorld:Function = (swfApp["playIt"] as Function);
helloWorld();
}
I want to call the parent function called "edit_groups()" from the itemRenderer. The code for my itemRenderer is:
<mx:VBox id="vbx_container" paddingBottom="4" paddingLeft="4" paddingRight="4" paddingTop="4" borderStyle="solid"
dropShadowEnabled="true" width="100%" height="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
<mx:Canvas width="100%" height="100%" horizontalScrollPolicy="off" verticalScrollPolicy="off" >
<mx:Image id="image" width="100" height="100" source="{data.thumb}" scaleContent="true" maintainAspectRatio="true"
complete="{image_smoothing_handler(event);}" trustContent="true" doubleClick="{Call The Parent Function"edit_groups()"}"/>
</mx:Canvas></mx:VBox>
And I call my itemRenderer from an application like:
list_groups_modify.itemRenderer=new ClassFactory(groups.list_groups_modify_item_renderer);
<mx:Label text="{data.label}" textAlign="center" maxWidth="60" toolTip="{data.label}"/>
