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.
View 2 RepliesI have a component with a public variable declared
[Bindable]
public var mnuSource:String;
When I extend this component, I can reference mnuSource (it compiles) but Runtime complains about the property not being accessible (error 1056).
How do you modify / declare component properties so they are actually available to other components?
I have an Item Renderer having HBox. Now I want to add child in that HBox from my application file using addChild method. Any way around for the same. I am not able to access the properties of HBox inside the item renderer.
View 1 RepliesI 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 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 {
}}

I'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'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"

I 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?
I made a very simple component to replace any component (e.g. a comboBox) on a form that is hidden if a user does not have access to change the value:

But regardless of whether or not objControl is visible, it doesn't get displayed.
I'm trying to pass some properties to a component I've created in Flash Builder 4. In my example below I want to pass the "label" property to update the label property of the Button.
// MyApp.mxml
<?xml version="1.0" encoding="utf-8"?>
<s:WindowedApplication xmlns:fx="[URL]"
xmlns:s="library://ns.adobe.com/flex/spark"
xmlns:mx="library://ns.adobe.com/flex/mx"

Is there a FLEX component that uploads multiple files in a multipart/form-data POST request?
View 3 Replieshow you set up data binding betweenDataSet and Tree component?
View 1 RepliesWhat 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.
how to properly setup binding between my Locale class and an mxml file.
My main mxml file contains:
<mx:Button id="TMP" label="{Locale.getLocaleString('title'}"/>
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 {...}

I have a datagroup where I use a custom itemRenderer with a datagrid inside. What I want is to access each datagroup's itemRenderer's datagrid and get it's dataProviderAll I know is that you can access the ItemRenderer by using myDataGroup.getElementAt(index)
View 1 RepliesI have some generic functions like copy, paste,etc in an AS file. I want to use them for editing data present in different mxml applications embedded in one application. If I pass the child's component id as a parameter of a function in one of the events, I get the value as either null or the parent app name. But I want the id of the child's component to access the values.

I need to access topBox's grandchildren and determine whether they're buttons or not. This function belowgrabs topBox's immediate children which are the HBoxes. How do I go one level lower to topBox's grandchildren? Or is the only way to do this is to run this function on each HBox?
for (var i : int =0; i<topBox.numChildren; i++){
var child : DisplayObject = topBox.getChildAt(i);
var myButton:UIComponent = child as UIComponent;

I'm building a top view 2D map, that it's objects are stored on the server.The kind of objects are 10 and might be a photo, label, button, lists, mix of them or labels with tooltips.The component must request the "areas" that are missing on screen.An area is 1000x1000 px and is cached in flex.To move in the map, will be like in google maps (drag-and-drop).I should be able to have another list and move objects from one to another using drag-an-drop on objects. Ex.: I grab an objects from a list and I move it on this map, I release the mouse button and the item is placed there.Now the problem is: I build a custom component for this trying to emulate the item renderer for performance and recyclage, implement drag-and-drop on objects and request the areas that are missing?
or
I extend the List component from spark and I add some features as multiple kind of itemrenderers and use recycle on them. Of course it must be able to request the missing areas on the screen and cache it's data.Maybe create a custom layout is needed too.What I need is something that must be really fluid, so the lighter this component is, the better.
UPDATE: *There will be not any object over another.
*I will not use hitTest on bitmaps because all bitmaps are wrapped in another component,as they,for now are itemrenderers.
Anyway I already begin to do this using a class that extends the SkinnableDataContainer and a custom layout. As the layout is not like a grid, is sparse, random items at diferent points(x, y).How to get the localX and localY, relative to item renderer and not to the Spark List, from a DragEvent in Flex 4?
This is the setup. I have created a timeline with a playhead. When my playhead is dragged I would like the timeline to scroll with the drag.
So far, the only way I can do this is by setting clipAndEnableScrolling to true. But in this case I lose the scrollbars(not to mention the impact on my view). So what I would like is to set this property to false and dynamically affect the horizontal scrollbar's position, in other words enable scrolling without the clipping.
How can I Access Items Selected in a Component from the Main App I've got a component that has a listControl and a couple of RadioButtonGroups. I need to access the selected items in the main application. What's the best/simplest way to create and access the array of selected items. So, the user clicks the button to confirm the selections and then I need to access those selections in the main app. Is there a way I can use a public var to build the array? Another idea?
<mx:Tile direction="horizontal">
<mx:Box>
<mx:Label text="Year" fontWeight="bold"/>
<mx:List id="myYear" >

I have a public variable set within fx:Script tags in a parent component that I'd like to access directly from a child component. How can I do this?

Note: SimpleComp is an HBox with a couple of lists.

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.
