What was the change in the textfield? I would want to compare the old text with the new text.the problem is, that I have multiple textAreas in a tab-editor, and all the textAreas are watched by one eventListener. I want to get a value calculated by the next formula[code]...

I am very new to flex and have trouble capturing the text change event of my text control:
<mx:Text id="description"
text=""
textAlign="center"
[code].....
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 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'm attempting to use the ENTER_FRAME event listener in order to change the text value of a field every 60 frames..I have the strings I want rotated out in an array that is being referenced in the if/else statement The movie doesn't even error out, it just doesn't work.
View 8 RepliesI need to put together an editable text area that has a custom caret (cursor) which is different from the default blinking vertical line. Is the caret a "skinnable" property of text input? note that I am not asking about the mouse pointer cursor which can be set using the CursorManager.
View 1 RepliesIs 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 RepliesI m using a dynamic text field in my app. I have added one Event.Change Listener on it. When I type into it with the keyboard, the event triggers. But when i set some text in it when user performs some action, like textfieldName.text = "test" then the event does not triggers. In this type of situation where we are not using keyboard, which listener should be added to text field to trigger the change event?

how do you change the text inside of a text control when a user has clicked a button. I could not find a way to do this. I used an event handler to input a .xml to a string and then to the text control. This doesn't seem to work.
View 1 RepliesI 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:

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 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?
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.
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 created a list control at runtime as following:

//Where myDataArray is an ArrayCollection consisting of my Custom ValueObjects. When i execute the code it displays my list with custom item renderer, which is fine. But when bring my mouse over it, it doesn't give any colour highlight which means it is not selecting. Secondly, when i click on any of the list item, it doesn't dispatch any change event. I tried a lot but couldn't understand it.
I am having a set of slider for each bar in the graph. I have bindded all the sliders with their corresponding bars. When i change the value of slider the value in the ArrayCollection changes and i have also used

View 1 RepliesI am using the flex datagrid to allow the user to edit some data. My update process relies on a CollectionEvent of type update. Basically I catch this event package the values and update the database. However, if the user edits a cell then moves to edit a cell in the same row the value is updated but a collection event is not fired. Only when clicking out of the row the event is fired. Has anyone had experience with this. I have heard the datagrid is a little quirky is this one of those quirks or am I doing this all wrong?
View 1 RepliesI created a somewhat custom Spark button by doing the File > New > MXML skin and basing it on spark.components.button. The problem is that I need to add an extra text field to the button component and dynamically change that text...but of course, the property isn't recognized on a Spark Button.
Is there a simple way to add this field to my custom button skin & its property so it can be addressed? If not, is there a simple way to take what I've done and just extend the Spark Button? I can't seem to find any examples that show how to do it without writing it all up in ActionScript.
