View 2 RepliesI am displaying a combo box in something of a WYSIWYG preview. I want the user to be able to click on the combo box and see the options inside, but I don't want them to be able to change the value. I tried using preventDefault() on the change event but it doesn't work. I don't want to disable it because I do want the user to be able to "look inside" the dropdown.
So I'm trying to block the change, but can't. My next resort is to change the selected index back to what it was before the change, Is there any way to do this within the scope of a ListEvent.CHANGE event listener?
Current Workaround is to basically re-assign the controls selected item the same way I am defining the selected item when I originally build it (a default selection). So a user sees their change then it immediately changes back to the default selection.
I want to change the value of a variable listed in an array using the array. for example:
Code:
var theVariable:Number = 15;
var theArray:Array = [theVariable];
now if I try this
Code:
theArray[0] = 20;
I just get an array with 1 value of 20 in it and it no longer references theVariable what i want to do is change the value of theVariable with out removing it from the array but referencing it from the array in a loop or something.
lets say i have dynamically duplicated movieClips ID's stored in array list. i want to add a onPress event to them. how do i do it?

Is there not an event that occurs only when there has been some sort of visual change to an object. So for example if it were a video or animated object it would be firing as often as EnterFrame. However, if it were some sort of input control just sitting there doing nothing visually, then the event wouldn't fire until the visual state changed as a result of some sort of user input for example.

View 3 RepliesCan I change an event target's name? or it's an only-read property? I've been googling it but to no avail... For example, say this is my button code:
[Code]...
if trace the event target's name, you get buttonOne. But what I need to do is have the event's target's name to become buttonOne1. because I already have a button with the instance name. That's my setup, not the way I would do it OF COURSE, but this is the way the unique file is setup for my aunt, to have two set of buttons that calls the same image...(not the thumbnail issue I had before)... so the Question: is there a way to add a letter or remove a letter from the event target's name? You know how you can add a letter to the beginning of an array like buttonsArray.unshift(newButton)....can you do the same thing with an event.target.name?
I've added the swfaddress library to my class for the changing of my website sections. I see the site in the browser but nothing change.I've debugged this class and i've seen that flash goes into the addressChange function but the fact is that nothing change in the browser address.Here the code:

I have a piece of software I'm working on that is using a viewstack with 3 canvases. With the change event I need to look for index 2 which is the last canvas when it changes to this canvas I need it to grab data from inputs from the previous two canvases.Within the viewstack events I've assigned the function change() to the event childIndexChange.
Here is the method:
private function change():void

I'm tracking how fast does the text of a textArea change. If it changes faster than 500 ms then i don't want to do anything, but if it doesn't change in 500 ms, i want to call a method.I tried like this:
public function textchangeListener(e : Event):void
{
if(((new Date).getTime() - changeTime)>500)[code].....
This method is the event handler for text change.But the problem is, if it changes only under 500 ms and after that it doesn't change, then my method won't be called. I make this for a better performance, so the prepareText() is called only when the user stops typing for 500 ms.
I have a Tree component that's used as a navigation menu between different 'pages'. When the user clicks a certain option in the menu, I switch the 'page' by switching between State components in my application. The thing is that when the user indeed clicks an option in the menu, I want to perform a validation of some of the information in a certain component. If the validation fails, I show an alert, and I'd like to prevent the navigation to the other page. One part of this is simply not changing the currentState of the document, but the tree component still goes on with the change event, and the result is page A still being shown on the screen, whereas the selected option in the tree is page B (to which the user wanted to navigate, but failed since some of the information wasn't valid).
I tried to figure out how I can cancel the change event on the tree component itself. The thoughts I had didn't quite fit nicely:
I searched for a slightly different event (such as 'changing' or 'startChange') on which I can call the stopPropagation() method (since the regular 'change' event is not cancelable), but none exists for the Tree component.
I also thought about always saving the current option that's selected in the Tree component by myself, and when the validation fails, I will set the Tree's selectedItem to that saved option. That's also ugly because such an action will raise another change event on the Tree, thus another change to the States components, and another population of the page in which I'm already at. That's something I really don't want to do.
I also though about using a different component, such as Menu (and I also found an implementation of a vertical Menu), but that doesn't even seem to help. The same problem will exist there.
There must be a best-practice for preventing a change process to commit!
I've successfully integrated SWFAddress deep linking on a site I'm working on. However I'm having a problem whereby SWFAddress CHANGE event isn't dispatched when you click an anchor tag in the htmlText of a textField. The browsers address bar is successfully updated, just no CHANGE event.
View 1 RepliesI have a custom component on which I have bound an array collection to one of its proeprties: <comp:MyComp id="comp" prop="{images}" /> images is an arraycollection In the components' code I would like to know which event to listen on everytime images updates props. I tried a setter on props but the setter only gets called once when props is first set. I tried the collection event but I get "Update" events sent on top of 'add' and 'remove' events and I would rather not have to manage those. So is there an event(flex or otherwise) that is fired every time a component property is updated by a bindable property?

I've got this weird problem with Flash in a embed browser in an ASP.NET Windows Application. I've got this Flash Movie that runs in the Windows application and has got a couple of comboboxes. I've added an eventlistener to such a box, but his change event isn't triggerd on some computers. When I click on the combobox it opens up, but when I click on an item in the combobox it closes before he could trigger the change event.
The weird part is that this occurs on some computers, on others it works as it should. And when I load the swf directly in the browser the comboboxes work all the time. So it has something to do with the Windows Application and Flash. All the tested computers have the Flash plugin version 9 and higher (needed for my movie) installed.
I was wondering if there was a way of tracking a variable change? Perhaps using some sort of event listener for it?
View 2 RepliesI have a playlist menu made up of movie clips acting as buttons, one clip for each track from a CD. The user clicks on a button, a corresponding sound clip plays and the movie clip button the user selected switches from frame 1 to frame 2 to change color while the sound is playing to show which track is currently playing.
Using an array to store the music tracks (named "Track 01" to "Track 08") and a "switch" command, my user is currently able to select and listen to a given track. My current problems lie with presentation.
I am having two problems with this project:
1. If the user allows the track to play through to the end, I need a single function to be fired on the SOUND_COMPLETE event (and I have applied the appropriate listener to my sound channel) which will reset the button to frame 1, as a visual indicator that the track has stopped. I have been unable to come up with such a function as yet.
Currently, the selected button just stays yellow (frame 2) instead of turning white (frame 1), and the user has to click twice (instead of once) to make the track play again.
2. My playlist includes a "play all" function to play all the tracks through in sequence as laid out in an array. While the track sequence plays fine, I would like to have the corresponding button for each track jump to frame 2 while that track is playing, then back to frame 1 when the track stops.

View 1 RepliesI have a standard combobox that dispatches a collection event when the dataprovider finishes initializing:
my_cb.addEventListener( CollectionEvent.COLLECTION_CHANGE, getMyStuff );
Then I have a custom component that also has a dataProvider. How do I get it to dispatch a collection change event when its dataprovider finishes loading?From what I've read, I can't do it. Will dispatching a propertychangeevent work?
UPDATE:I have a custom component that I call 'SortingComboBox' but it is not a ComboBox at all; it extends Button and I set is dataProvider property to my arraycollection, model.product (which is an arraycollection). how I use the dataProvider in that component:
code
[Bindable]
private var _dataProvider : Object;
public function get dataProvider() : Object
{[code]..........
In the createChildren() method of this component, I use this:
BindingUtils.bindProperty(dropDown, "dataProvider", this, "dataProvider");
The dropDown is a custom VBox that I use to display labels.
<s:Button id="btnNext" label="Next" width="80"
click.Title="changeState('Info');"
click.Info="changeState('Organ');"
/>
How do I dynamically change the "click.Title" event in actionScript?
btnNext.addEventListener(MouseEvent.CLICK, ??
I've got a component called Box.as that has following two properties, and have their getters & setters defined:
private var _busy:Boolean;
private var _errorMessage:String;
In MXML that uses this component I define it like this:
<components:Box skinClass="skins.components.BoxSkin"
busy="{presenter.boxBusy}"
errorMessage="{presenter.boxErrorMessage}"/>
Where presenter variable is defined here in MXML and a Presenter class has boxBusy and boxErrorMessage variables defined as bindable property change events:
[Bindable(event="propertyChange")]
function get boxBusy():Boolean;
function set boxBusy(value:Boolean):void;
[Code]....
PROBLEM is that whenever I change boxErrorMessage for the presenter, I see the affect in MXML but nothing happens at all when I change boxBusy. Is there something extra I need to do with boolean variable?
I'm currently using the change event handler to detect any changes made to the combobox selection, however, I would like it to ignore when the arrow keys are pressed as I am using them elsewhere.
