I am using a custom component within another custom component in a flex mxml application file.Is it possible to bubble events from an inner component to the outer component and handle events in the outer component?
View 3 RepliesI'm trapping keyboard events on the stage and dispatching custom events through a framework (Mate, though I don't know that this is an important issue), but I'm pretty confused by the scope. The structure is:application (traps keyboard events and dispatches custom event mainPanel (receives dispatched events but mainCalendar (a child element) is null on debugging. Obviously if I try to call a public method on mainCalendar it errors out, even though it's a child of mainPanel. However, mainCalendar is NOT null IF I use FlexGlobals.topLevelApplication.mainPanel.mainCalendar. Outerdocument and parentDocument do not expose mainCalendar either, BTW mainCalendar (a custom component inside mainPanel with public methods. Creation policy is 'all' and it's visible and exists long before I trap any keystrokes at the top level)Could someone take a minute and explain why the mainCalendar is out of scope when mainPanel receives a custom event, even though mainCalendar is a child of mainPanel. Is there a better way to manage the events so I don't have to always address the component via the topLevelApplication?
View 1 RepliesI am created a dynamically adding a VBox, that contains two images. Into a Custom Component that is derived from UIComponent. The problem is the Vbox that contains the two image is only a really tiny size. I would like the VBox stretch to the size of the two images. This is how I am creating the Vbox....

I want to create a custom component library. the components are customize-able during creation time. means like Accordion or TabNavigator, when we drag and drop the Accordion in flash builder it

I have Flex 4 application in which I have one component as top layer which displays something like tooltips, basically user sees "presentation" which explains usage and meaning of the tools "below", sliders, checkboxes, text fields etc. I made this "presentation" using sequences so first tooltip is visible, then becomes invisible, second is visible etc.
I tried to disable mouseChildren, mouseEnabled and other possible parameters which would disable those tooltips from preventing user clicking on some button or checkbox. Obviously those components which render tooltips even tough invisible, are still "clickable".
I'm new to Flex and am having trouble understanding Events. I think Events are what I want to use for my situation. I have 2 components, addUser.mxml and listUsers.mxml. I access these from a ViewStack in my main application. When I load listUsers.mxml it shows a list of current users in a datagrid via a HTTPService call. When I add a user using the form on addUser.mxml I would like the datagrid in listUsers.mxml to refresh when I return to that view to show the new user. I've tried several different things with addEventListener and dispatchEvent but can't seem to get it working. Can someone help me with this logic?

We are building an interface for a game. The interface has a tabbed menu at the bottom of the screen, with each tab displaying different aspects of an object (called a node). When you click on one of these parts, it becomes the focus, and we download it's details in XML, including all it's sub-nodes and parent nodes and then update the tab display accordingly, or at least that's what we'd like to happen.
What we have:
MainInterface.mxml
<s:Application...
<fx:Script>
<![CDATA[
public var currentNode:Node = new Node();

We tried adding an event listener for "selectNode" to the dashBoard:SkinnableContainer you see see above, but it didn't seem to want to take. We suspect this is because dashBoard is from a spark component and the dispatcher for "selectNode" is on of our own custom components, but we weren't sure... in any case that's what the code assist seemed to indicate as we had to write it in by hand. We're not sure how to pick up the Events in FlashBuilder 4's debugger, so we're having trouble working out where it's going wrong.
Basically, when someone clicks on the label of a child or parent node (that is displayed by the itemRenderer), we want a URLRequest sent to our website, with the url specific to the node clicked on. We then want a URLLoader listening for the return which will update public variable 'currentNode' when xmlDownloaded is called by the loader. If you could clarify how the click event should be dispatched, what should be listening for it then sending the URLRequest and where the URLLoader that is listening for the xml data to return should be that would solve our problems.

View 2 RepliesI've written the following custom component, SubNavBar.mxml:
<?xml version="1.0" encoding="utf-8"?>
<mx:Canvas xmlns:mx="http://www.adobe.com/2006/mxml" height="100" width="300"
creationComplete="init()">
<mx:Script>

Whenever the trace function runs in init(), the property menuItems returns null. I don't seem to have this problem with other variable types, like Boolean or String. Is this due to the size of the XMLListCollection object? How can I set up this SubNavBar custom component with XMLListCollection property and bind it to a control in the component?
I am new to Flex programming. I want to implement a custom toolstrip for an app. This tool strip will include a menu bar (or a customized equivalent) to display the common menu items such as File, Edit, etc as well as a search box. It should be flexible enough to include other menu items such as bookmarks, etc in the future. I have been thinking about mx:Group, s:BorderContainer, mx:HBox, but haven't been able to choose between them. And none of them seem espcially suited to my task as they merely specify layout of other objects. Is there any component which has direct support for such functionality. I have also thought about using mx:MenuBar but I don't know if it will be flexible enough to add non-menu items like search box.

I have written a custom component for drawing a circle in Flex. But When I try to write a click event or mouseDown event for that component, it doesn't work.[code]...
The "Hello" Alert is displayed only at a particular point and guess is, at the point, (175,150) the x, y co-ordinates of the circle. But shouldn't it be displayed wherever I click on the MyCircle component?? how to enable it in that way?
Also the mouseDown function doesn't work for MyCircle,but if have the event for the VBox, the Alerts are displayed.
Basically I am trying to create a string Validator which requests a new language from its controller by dispatching an event upon its creation.
The example below is a straight copy from the Flex3 component explorer - the only diffrence being that I have created the validator as a custom component which dispatches an event upon its creation.
The problem is that my main Application cannot hear the event being dispatched and I don't know why.
Here is the example
MyValidator.as

import flash.events.Event;

I have an <mx:Application> which contains a <mx:Module>. This module has several child modules. It also has some an instance of a class I have created. I am trying to have a method of this class dispatch an event that can be "heard" by the module and handled. This isn't happening.To be more clear, I am using 'dispatchEvent' to from inside a class method.There is an instance of this class in: mx.core.Application.myapplication.mymodule.myclassIt is the 'myclass.somefunction' that dispatches the event. I have a listener registered in 'mymodule'. Nothing happens when the function/method runs, however.
View 1 RepliesI'm taking my first stab at writing a custom flex 4 component by extending the UIComponent class. Unfortunately, I cannot get the component to respond to any sort of mouse events.I've tried setting mouseEnabled to true is the component, as well as setting mouseChildren to true in the parent (the stage object). It seems whatever I do, my click events can be detected from the stage, but not with the component.Here is my component class:

View 1 RepliesI have to create a custom header for the AdvancedDataGrid component. The custom header must have two buttons in it. The custom renderer must be applied to more than one column.
How I can fire, dispatch and handle events from the custom headers?
I have multiple items in my app that I would like the user to click on.Some items are completely different classes.The classes dispatch events and then when the events are captured, some modifications are done to the transform properties of a loosely coupled display object.I want two separate classes to dispatch the same type of event, since I already have an image class that draws images based on a given url... I want the classes to dispatch the events, but then I think I want the difference to be detected when the event comes along... i.e., I would like to recognize the 'origin' or 'sub-type' of the event. Some sort of if/then logic would suffice.
View 1 RepliesI've been developing in flash for about 5 years now and consider myself a solid intermediate level developer, but I have a gap in my knowledge of events. I don't understand when bubbling events or catching events would be beneficial. I'm guessing there is a very obvious use for them, and being mostly self taught I've probably developed 'work arounds' to solve whatever issue they fix.
I've read the documentation and programmed a few test cases, but either for the interfaces I've developed or for whatever reason I've never ended up using them.
What is event bubbling in Flex?

View 2 RepliesA swf (my game framework) loads another swf (a game). The game is loaded into a child domain which seems to be the default domain for loaded swfs.
The framework listens for custom events bubbling up from the game. However, the framework only receives events dispatched directly from the games document class but not from any of the games children.
Bubbling is set to true on everything, but it's not working? Is it only possible to dispatch events from the document class of the loaded swf.
swf(Framework -> listen) -> swf(game document root -> child) = no go!
I have a wrapper swf which loads the main content swf.I've been successfully hearing custom events in the wrapper swf dispatched from the main swf, but only if they're the kind like this:
Code:
// main
dispatchEvent(new Event("LOADING_CONTENT"));
