Is there any shortcut way to add an eventListener to something like a select event for NavigatorContent. I am aware I can add a listener for a change event on the ViewStack and identify the selected NavigatorContent through that handler.
View 1 Replies"Stab" is a tabnavigator, I like to access the id within navigatorcontent which is datagrid. I tried getchildbyname can't it can't seem to find the datagrid "nc1,nc2, etc" and return null.

How can i trigger an event for the scaleX property change of the movieClip or Sprite in Flash AS 3.
View 1 RepliesI have the following code:
Code:
btn.addEventListener(MouseEvent.CLICK, select);
function select(evt:MouseEvent):void {
addEventListener(MouseEvent.CLICK, unselect);
} function unselect(evt:MouseEvent):void {
removeEventListener(MouseEvent.CLICK, unselect);
}
The idea is to be able to select the "btn" sprite and while it is selected you can click anywhere on stage to deselect it. I thought this would work but somehow after a single mouse click it also executes the unselect function. Since I add this function after the mouseclick I do not understand why it is doing this. Is this not the way to do such a thing?

Flex 4 Combobox is extended with a Text Input that helps in getting to the item that is searched for.I have created a Check Box as an itemrenderer for this Flex 4 Combobox. I would like to Add a Select All and Select None options in the drop down of the Combobox. I know that i could accomplish by editing the dropdownfactory in case of a Flex 3 Combobox. But in Flex 4 the dropdownfactory doesnt exist.

When the escape key is released, I close the deepest child in a tree-like structure, and then tell it's parent (which is now the new 'deepest child') to close when the escape key is released ... but I do that while such an event is triggered, that causes the whole chain to close.
View 3 RepliesI'm new to AS3.0 Is there a good way to deal with many event listeners like say MouseEvent.MOUSE_OVER and MouseEvent.MOUSE_OUT for the same type of movie clips? I've been getting the following error if the mouse rolled over or out too fast.

In my scrolling code I want to remove the eventListener for my reportStageMouse event, but I get an error: 1120: Access of undefined property reportStageMouse.

View 7 RepliesHow can I access to an object who fires an eventListener event?
Let's say I have a mc:
var element = new MovieClip();
which has an eventlistener:
element.addEventListener(MouseEvent.CLICK, elementEventHandler);
[Code]....
So that is what I want to achieve... Recover the object who fired the event and then do crazy things with it (in this example, add another object in it).
pd: yes, I know I can directly use the var element in this snippet, but in the real code I'm generating the mcs in a loop, according to a xml file.
I want to call the same event handler function with a click and also with a custom event. the problem is the event type that needs to be passed to the function. Is there are generic event type that can be used to call the function from both places?

I have a MouseEvent.MOUSE_WHEEL eventlistener setup for a custom scrollbar component that allows the wheel to control the scrolling up or down.Inside the Flash dev environment when I test the flash app it works fine. However, when I test the app inside a web browser ( which has its own vertical scrollbar ) the mouse wheel controls both the scrollbar in my flash app and the scrollbar in the browser.Is there a way to setup the eventlistener on my scrollbar that it prevents the MOUSE_WHEEL event from bubbling up to the browser?

I'm trying to do something with eventListeners, but i still do a lot of messy code, so wanted help of those who already know flex.
I'm have a DataGrid, and its itens are added by another component, no problems with that.
I have buttons to Add, Remove and Edit the items inside the DataGrid. No problem with that too.
But i want those button to be enabled when the DataGrid as at least one item, and when it doesn't as any, all three buttons should be disabled.
EDIT: Forgot to say: I think eventListeners are the best way.
I am working in air application , i need to know how to add event listener when any object is updated,how can i implement this.Example:i have Class name Vehicle, and child class are Car,Bus,Bikes,Scooter,..etc, child class also have many properties like color,model no,....etc
I have array collection and AddChild() method in Vehicle class by this, i will add, child class to the vehicle class.I need a event listener which can trigger if any of the property is updated or changed in any of the child class property, how can i implements this in Flex3.
I'm trying to remove an eventlistener on (in this specific case) a HorizontalList. The list is initialized with the property itemRollOver="playPreview(event)" I'd like to remove this eventListener by switching state and stating something like: <mx:SetEventHandler target="{horList}" name="itemRollOver" handlerFunction="null" />
This doesn't seem to work. The event is still handled and playPreview(event:ListEvent) is still called. How to properly do this? (I know I can do it in Actionscript, but I specifically want to do it by means of state switching)
I'm trying to make a global eventListener. Everything works fine, the KeyboardEvent.KEY_DOWN fires all the time .. except the cases when the textInput has a focus.Here's how I attach listener:
FlexGlobals.topLevelApplication.systemManager.addEventListener(KeyboardEvent.KEY_DOWN, keyDownHandler, true);I've tried both (use capture and without it).
I'm sure this is a easy one but I've been searching for a while how to select a DropDownList element with actionscript. In this scenario, I'd like to be able to specify the selectedItem based either on ddlLabel or ddlData

I hava a custom component and it contains a child icon. If I add a mouse-click event listener to both component(click-listener1) and icon(click-listener2), the event dispatched sequence is click-listener2, then click-listener1. I can understand it. But if I add a custom event to component (listener1), and mouse-click event to icon(listener2), when icon is clicked, the component will dispatch the custom event. In my test, the event dispatched sequence is listener1, then listener2. It doesn't match with event-bubbles rule.
In my opinion The custom event is dispatched in listener2, which triggers listener1. Why event flow sequence is not listener2, listener1?
In component.
icon.addEventListener(MouseEvent.CLICK, iconClickHandler);
private function iconClickHandler(event:MouseEvent):void

In a flex datagrid, by default clicking on column headers does sorting. I want it such that if a user clicks a column header the entire column is selected. I have the datagrid listening for the HEADER_RELEASE event so I know when the column header is clicked.
How can I have the column and header appear highlighted similar to how a row is highlighted when selected?
