Flex :: Make TextArea Dispatch An Event Each Time A New Line Is Taken?
Nov 1, 2010
Every time a user takes a new line (i.e each time they press the return/enter key) when typing in a textArea, I would like the textArea to dispatch an event.I can then listen for this event and then carry out some processing on the textArea's contents.
I am having trouble using a custom event in flex. I need to dispatch an event from inside two nested components and receive it in the main application file. The basic set up is a main application file importing a custom "gallery" component.
if I type any thing in textarea, then this colorize() function is called twice. How can I stop this one that both event should not be triggered together.
I'm new to Flex.My question is how to dispatch event between components?As far as I know,Flex only bubbles event to itself or its parent. I'm in such a situation:

I want comp1 to dispatch an Event with parameters,according to the parameters some changes could be made to A and B in comp2.How could I get the event in comp2?I know Cairngorm could make a difference,but I don't want to use it right now.Could anyone give me a hand?
Where, in this case, _list is an ArrayCollection object whose filter function depends on the showAll field to choose values.It turns out that this doesn't work, or at least gives a strong appearance of not working (what with the values in the list not changing and all). Is there a documented order of events for this, so that I can discover which events are dispatched in which order, and whether the binding value change will have fired the time the click event is dispatched? Alternately, can someone recommend a better way of doing this?
Is there a way how modules can listen to parent application event? My current solution that works is:
private function directoryRemoteObject_saveCompany_resultHandler(e:ResultEvent):void { this.directoryModuleLoader.child.dispatchEvent(new CompanyEvent(CompanyEvent.COMPANY_SAVED, e.result as int)); }
this means that I need to dispatch event for every module.
So I'm trying to build a tool that will allow me and other users to all open the same .swf, and then I as the Admin user am able to interact with mine while they all see my mouse movements and button clicks etc on theirs.I'm using BlazeDS to manage this and I'm getting data sent back and forth etc - no difficulties there. The issue I'm running into is this:
In an "Admin" instance, I click a button. I capture that X and Y, then tell Blaze to tell my clients to dispatch a Click event at that X and Y. On my client side, I get that data and dispatch a Click event at that X and Y - but the click is actually caught at the stage level. The click on my client side takes place UNDER all of my buttons and other content - so the whole thing fails.Is there a way to tell it to start the click event at the top?
What I want to do is to dispatch the click event when the component is clicked. (The class is essentially some text in a textfield that needs to be able to do certain things, and it needs to be able to respond to a click). Sounds easy enough... I want the event dispatched when that portion of the text is clicked. But uh...how? it's not like a button where I can just go myButton.addEventListener(MouseEvent.CLICK, myClickHandler);That's clear, because some component is going to be listening for the Click event dispatched when myButton is clicked. It is built into the AS3 framework that a button knows how to listen for a click event.
After the import statements I've got:[Event(name="click" type="mx.events.Event")]How do I dispatch the event when the component is clicked, when the component doesn't yet know how to respond to a click event? I've tried adding an event listener in the textfield which contains this custom class of text, but nothing's happening because the Click event hasn't been dispatched.
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:
I'm fairly experienced with Flex 4, but I still haven't needed frameworks yet (I like to do everything myself) and don't want to use them either, I know it's advantages and have learned how to use one of them, but still, no.
How can I dispatch an event in the main application and have a component inside a popupmanager to react to that event? All this dispatching the event within the main app and NOT aiming it to the popupmanager or the component instance, I want to be able to fire the event and not care about who gets it or if anyone reacts to it at all so if that is possible then I wouldn't care about keeping track of said popups.
I already dispatch an event from the component and receive it in the main application by bubbling the event and therefore being agnostic of each other, now I want it backwards.
Is there an event dispatched when a modal is brought to the front in Flex? Basically there are two times when I would want to listen for this event: When the modal is first created (although in theory creationComplete / show / etc.. could suffice here). When the user brings a modal that is not in the front to the front by clicking on it. In my case the popups I am working with are descendants of TitleWindow and listening for focusIn does not seem to work reliably.
I will need to execute a function in a comp1.mxml from main.mxml through event, I found it difficulty to understand and unable to get it work.[code]...
I got a question about event dispatching and dispatching in flex.
My goal is to pass an email address captured in one component (Comp1) and be passed to another (Comp2). These two components are navigator content of a viewstack. The custom event dispatched the email correctly from Comp1 but somehow could not reach Comp2. The application (Main) looks like :
I am trying to get some code working from an example I came across. most of the functionality works but it is failing when it tries to dispatch a custom event. At the moment the code that is trying to dispatch the event is inside a class that handles amf remoting.the example has this line in it for the dispatch:
I am trying to dispatch a custom event from one flex module to another.The code which dispatch the event is as below Application.application.Destination.child.dispatchEvent( new AlgoEvent(AlgoEvent.GETFROMPARENT_LOCAL_EVENT));
here AlgoEvent is a custom event.on the other side the module which catches and handles the event has this code:
public function sendParametersToChild(e:AlgoEvent):void {[ code]...
but when the statement Application.application.Destination.child.dispatchEvent(new AlgoEvent(AlgoEvent.GETFROMPARENT_LOCAL_EVENT)); is executed the debugger give the following run time exception:
TypeError: Error #1034: Type Coercion failed: cannot convert resources.events:: AlgoEvent@4182239 to resources.events.AlgoEvent.at flash.events::EventDispatcher/dispatchEventFunction()[code]...........
My issue is that for my website I want there to be movies in between the interactive parts of it where the interfaces slide in and out. However, I can't stop a movie from playing over and over instead of playing once and going to the next frame.With 2.0 I haven't been able to find any research that helps me, probably because I don't know the correct keywords to search for.Right now I have my main time line set up with a loading bar on frames 1 & 2, that then jumps to frame 3 where I have embedded a movie (Instance named: mc_start) of the interface sliding in. Preferably after that I need it to jump to frame 4 where the actual interface is.
I can get the movie to end by going into the embedded movie's time line and simply have stop() ; at the final frame, but I can't get it to go to frame 4 on the main time line. If I having something like gotoAndPlay(4) ; on the final frame of the embedded movie's time line, it simply goes to frame 4 of the embedded time line and not frame 4 of the main time line. If there was a command to make it jump back to the main time line instead of the embedded time line, that would work perfectly.Coding on Frame 3 of the main time line to jump to Frame 4 would work if I knew the correct language to detect when the movie has ended (Movie is 191 frames long), so that afterwards it would immediately jump to Frame 4, but I haven't been able to find any resources that will teach me how to do it. Right now having gotoAndPlay(4) ; on Frame 3 of the main time line obviously makes it immediately skip the movie on Frame 3 and jump to Frame 4.
What I have is a movieclip and a button in scene 1 (which is the main timeline).There is an actionscript layer also on the main timeline. what I want to do is when I click the button, it would do a nextFrame(); in the movieclip timeline instead of the main timeline.
