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 am using the following .as file as the component for an itemrenderer in a list. Basically each item is rendered in a TextInput and each TextInput has a remove button as you can see from the code. When clicking the remove button, I want to remove the selectedItem..so I am putting the function removeItem() in MainMxml.xml and calling it from the .as file.
However I am getting an error "Cannot access a method or property of a null object reference".
The .as file as follows:
package components {
import flash.events.Event;
import flash.events.MouseEvent;

I've got a text field that initiates a function when the link is clicked, but after it's clicked I want to attach a different function to the text field, but It doesn't initiate with this one still active.
fullText.htmlText = '<a href="event:fullText"><u>Full Image</u></a>';
fullText.addEventListener("link",function(e:TextEvent){fullSize(num,fu llText); },false,0,true);

I am struggling with this. I have an EventListener function that receives a parameter. For any reason, seems that Flash doesn't like it when is time to REMOVE it:
Code:
var counter:Number = 0;
btnCreate.addEventListener(MouseEvent.CLICK,Create);
btnRemove.addEventListener(MouseEvent.CLICK,Remove);[code]......
What is the trick to remove an EventListener when it does have a parameter?
What the syntax is for removing the listener when writing it shorthand?[code]...
View 2 RepliesI have a movie placed on stage (on first frame of Timeline) and an Event.ENTER_FRAME EventListener inside the movie, when I click a button on stage that takes me to 2nd frame, I want to remove the Event Listener inside the movie. How can that be done.
View 3 RepliesI am trying to remove an eventlisnter on a button so when the button is pressed the animation completes before you can press the button again. But based on my code below you can push the button as many times as you like:
var LeftButt:MovieClip = new left_button();
var RightButt:MovieClip = new right_button();
var topClip:Sprite = new Sprite();

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. I am trying to remove the listener in my mouseUpOnStage event. I assume I cant remove the listener because it's in a nested function? [code]
View 7 RepliesI am trying to remove the EventListener after I click on a MovieClip so that when I rollOut of the clip the movie will stay on the "clicked" frame rather than move back to the rollOut frame.

straight into the code - mps is a OSMF video instance - when it has finished playing through the TimeEvent - I can remove its listener but not remove it from the stage - why is this not working!?

function removeVideo(t:TimeEvent):void

I have an array of buttons in a public var in _model.btnArray. I want to make a function that i can pass an index number parameter that will add addEventListener to the button at that index and removeEventListener to all other buttons in the array. The function creates a tempArray:Array and assigns _model.btnArray to it. Then it addEventListener to the index passed as a parameter to the function. Then it splices the passed index out of the tempArray and then loops through spliced tempArray to remove all the EventListeners from it. which should be the listeners on all the buttons except for that one spliced. but this isn't working, its giving me an error and i don't know why.should this be working or is it just wrong?
Code:
function addRemoveEventListener(num:Number){
var tempArray:Array = _model.btnArray;

Problem is that I can't remove Event.COMPLETE event listener and when I call the loadData funtion twice or more, it works 2 times or more. Sorry for my bad english and worse explanation but I need to fix it today and I don't know what to do.

This is my code in Flash/AS3, in main class.
addEventListener(Event.ENTER_FRAME,function(e:Event){

I have a movie placed on stage (on first frame of Timeline) and an Event.ENTER_FRAME EventListener inside the movie , when I click a button on stage that takes me to 2nd frame, I want to remove the Event Listener inside the movie. How can that be done.
View 1 RepliesI'm trying to override the addEventListener function to input an extra line of code to put the event listener type in an array so I can remove it all at once.But the override function doesn't seems to run.
Code:
override public function addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = true):void

i have a problem using the itemRenderer functionality. When using an ArrayCollection the visible Data in the DataGrid using the itemRenderer will be rendered just fine. But if i start scrolling the entries are repeating in the cells using the renderer. The cells are not filled with date according to the id. What mistake i'm doing here.
I read a lot of the explainations like:

Anyone know how to change a single instance of an item renderer for a Flex tree item at runtime? To reiterate, I'm not trying to change the entire tree's item renderer like this:tree.itemRenderer = new ClassFactory(ItemRenderer2);I'm trying to change the item renderer of a single tree item like this (the following code does not work):tree.selectedItem.itemRenderer = new ClassFactory(ItemRenderer2);To put it more simply, does anyone know how to reference an instance of an item renderer and set it to a new item renderer class? I've tried using the Tree's itemToItemRenderer() method with no success.
View 1 RepliesI have implemented drag and drop between 2 AdvancedDataGrid, but the default behaviour from Flex displays the row data during the drag using the grid item renderer showing all 5 columns.
Instead, I would like to display an icon / image or my own custom item renderer during the drag and drop.
I want to create a list of progress bars and update the list accordingly.I have group data in an Array as
<mx:Array id="arr">
<mx:Object label="Group One" min="0" max="200" currentValue="60" />
<mx:Object label="Group Two" min="0" max="300" currentValue="50" />[code]....
The values in the array object indicate name of group,minimum,maximum and current value for the group (to be used in progressbar).I used the list with "mx.controls.ProgressBar" as itemRenderer as
<mx:List width="100%" dataProvider="{arr}"
itemRenderer="mx.controls.ProgressBar"/>
Now what I need is whenever currentValue field of Array "arr" changes i want to update the progressbar "progress" value to currentValue (where min and maximum value of progressbar are stored in Array "arr").
How can we navigate within an itemRenderer? For example, in Views we use the View.navigator (ViewNavigator) to push and pop views, there is no such feature in ItemRenderer.
Navigation within a View (Easy)
<s:View>
<s:HGroup >
<s:Button label="Questionnaire" click="navigator.pushView(view.QuestionnaireCategory1View)"/>
</s:HGroup>
Navigation within a Item Renderer (Impossible?)

I have a List which has TextInput as itemRenderers for all its items. Upon application launch the items are rendered in the TextInputs correctly. The data is being populated from an Array of Objects.
What I want is, after the data has been populated in the ItemRenderers, I want to have an additional item renderer (TextInput of course)...so that if the user wants to enter another item, he can put it in the additional textInput.
And I also want to add the additional itemRenderer each time the user has added a new item and taps ENTER on the newly added item.
Below is my itemRenderer, there is the clearTxt_enterHandler handler..but I wonder how to add another itemRenderer upon "Enter".

I have an AC with several questions and assoicated answers. These must be shown in a DG, and the idea is that the rows and colums of the DG are bound to the AC. For example, if the answer to question1 is Yes, the Yes-button must be true, and both the others must be false (as in normal radiobuttongroup behaviour). But when I change a button by clicking it, the actions datafield of the AC should change accordingly. Am I clear enough here?
It is ment for dynamic questionnaires.

What is the Difference between ItemRenderer and ItemEditor?And When ItemRenderer is initializing and loading?
View 1 RepliesI've created a custom ItemRenderer extending UIComponent and implementing IListItemRenderer. This renderer contains a Text-Object to display the value.
For editing I'm using the standard ItemEditor (TextInput).
Now, when I want to edit a value, I click on a cell and the editor is created. But instead of displaying the value which was displayed in the renderer, "[object Object]" is displayed.
I am using a custom componenet based off of text as an itemRenderer for a dataGrid that is displaying an XMLList. I want to be able to re-use this itemRenderer for multiple columns, how do I access the dataGridColumn so I know which field to assign to the text value?
super.data gives me the whole XML item, super.parentDocument gives me the whole DataGrid
