ActionScript 3.0 :: Identifying A Clicked Element From MouseEvent?
Dec 9, 2009
I have several array element each assigned to different symbols on the stage and now I have assigned one function (fcn1) for each element's MOUSE_OVER event as follows:.
for(h = 0; h < fields.length; h++)
{
fields[h].addEventListener(MouseEvent.MOUSE_OVER, fcn1);
[code]....
Now in fcn1, I have to identify which element the mouse was over it. I could not do this because I can't pass any parameter to fcn1 other than e:MouseEvent. And I tried to look the properties and methods of e:MouseEvent that might give any information about the source element (in this case, array elements).So far, only way out of this was I create function for each array element which in turn call fcn1 with appropriate parameter, but it is cluttery.
My problem is that I'm not sure how to make the MouseEvent.MOUSE_OVER work, to recognize that the mouse is still ON the area and so pubsBox should continue to move 10 pixels to the left every second. I understand that i have to use a Timer, but what I'm concerned about is the fact that I can't get Flex to recognize that the mouse is still OVER "wrapper" and continue firing the event.
I am dynamically creating 10 textinputs inside a vgroup . when user clicks a button, I want to fetch the text present on all textinputs. How to do this. My code looks like this
var vgroup:VGroup = new VGroup; for(var i:number=0;i<10;i++){ var textinput:TextInput=new TextInput(); vgroup.addElement(textinput): }
I am working on a sample map application using Flex 4/fxg? Now I have got FXG paths held in Group elements with id's( I have assigned path's id's to the corresponding group container)? But when I click anywhere in the map, I do not get the clicked group as target/currentTarget in event handler. How to determine which element is clicked?
Say, I have an array of movie clips (dummies). Each dummy has an event listener and reacts to clicks. And when a dummy is clicked, I want to know the index of the clicked dummy.
I've only come up with this solution: run through the whole array of dummies and find out which dummy is the target, then exit the 'for' cycle and assign some global variable the value of counter variable, but this way the application I am building will demontsrate poor performance.

In below class I ave declared an array "selectedOptions". In click event Im storing the values in it. But everytime I click on the object the array gets initialized and stores the clicked element rather storing all the elements one by one. Could you tell me the reason?
I'm trying to check if a clicked element is inside of an IVisualElement in Flex 4. So I want something like "if this element is in this element, then execute function". I'm aware of the 'parent' property but this doesn't seem to work when my element is not a direct child of the element but for example 3 levels deep.
I have several stage event handlers to enable mouseovers over several dynamically generated moviecilps on the stage that then change their alpha to indicate the mouse is over that particular mc... fairly trivial (mcOver handler). Additionally, I also want to know what MC is clicked, so I update a public variable (public var activemc:Number) with the ID of the dynamic movieclip when the mouse is over it (using a hitTest to check, which is why the EventListener is added to stage and not to the MC), which is checked in the mcClicked handler:This is in the constructor:
However, the mouseover behaviour (alpha 0 when over, alpha 1 when out) stops working as soon as I click on any movieclip on the stage, and the mcClicked ID checking (below) stops working completely. I don't know if this is to do with focus:
private function mcClicked(event:MouseEvent):void { myTextField.text = String(activemc); // activemc is a public var:Number with the movieclip //ID }
I then tried adding the event handler for the stage mouse_move again and this gets the mouseover working again but only for 1 more click, after which it stops again:
private function mcClicked(event:MouseEvent):void { myTextField.text = String(activemc); // activemc is a public var:Number with the movieclip //ID stage.addEventListener(MouseEvent.MOUSE_MOVE, mcOver);
I have a MovieClip (call it base_mc) which is under a bunch of other MovieClips (call them subclips). The MovieClips on top are all mouseEnabled with MOUSE_OVER, CLICK, etc, event handlers. I want to capture the event of MOUSE_OVER (or ROLL_OVER) on the base_mc as well. Any time I am over one of the subclips I am also over the base_mc clip. How can I capture this event?
I'd like to know what is the difference between MouseEvent.CLICK & MouseEvent.MOUSE_DOWN. Because when i use MouseEvent.MOUSE_DOWN for a button to set full-screen view its doesn't work, instead of this MouseEvent.CLICK works. So what was the reason.
I'm making a button for the first time, and I wanted to use a full click to drive it. However, when I use addEventListener(MouseEvent.CLICK, onClickHandler); nothing happens when I click on it. When I use (with the rest of the code being identical) addEventListener(MouseEvent. MOUSE_ down, onClickHandler); it works like a charm.
I have a MOUSE_DOWN handler that creates a CLICK event listener on a child object. Naturally, as soon as you release the mouse button, if you happen to be over the child object, the CLICK event fires.I was disappointed to discover that event.stopImmediatePropagation doesn't interrupt the CLICK event from registering the MOUSE_DOWN as part of its detection cycle. It makes sense that it doesn't but still... disappointing.A MouseEvent.CLICK consists of detecting a MOUSE_DOWN on the object and then if it's followed by a MOUSE_UP without leaving the object, he event fires. I had hoped that by cancelling the MOUSE_DOWN event, it would clear that out of the CLICK buffer, but no such potatoes, alas.This could all be handled with a flag and a couple more MOUSE_UP and MOUSE_DOWN handlers, but dang, smacks of effort
rwBtn.addEventListener(MouseEvent.MOUSE_OVER, audioOver); function audioOver(e:MouseEvent):void { var thisClip:MovieClip = e.relatedObject; thisClip.alpha = 0; }
I would like to change the alpha of the clip that is being rolled over. I don't know how to target the clip that is being rolled over. How do I do that?
I know that there is no such function as getElementByName in Flex but I also now that you can do this["object_id"] to get the element of the application u're in.What about getting an element inside another element?I've tried making element["id"] ? But in my try-catch it always runs the "catch" part..how do I get an element inside another element just having it's id in dynamically created string form?
I have an AS3 application which seems to be leaking memory slowly while running. I've been looking for a profiler for Flex 2 / AS3 and haven't been able to find one yet, in fact I saw posts from people at Adobe saying they were working on it but no release in the short term!
Does anyone have any more news on this, or more usefully have any information on a profiler or other way it is possible to find memory allocation and usage during runtime of an AS3 application? It would really help me to identify what areas of my application are leaking memory.
I have an xml and it has items, you can trace the items in Flash, but how do I call them to allow me to identify that object getting clicked on the stage?
I have 16 layers of movieclips (one in each layer), each has been given the instance name, "line1" through to "line 16". I'm trying to figure out how to hide all of them through actionscript, so far, my code is:
for(x=1; x<17; x++){ line[x]._visible = false; }
but for some reason, it doesn't hide all the instances. I've tried typing it in seperatly, (line1._visible = false; , line2._visible = false; , etc...) and it works, but for some reason, when I use the for loop, it doesn't work..
I've been scouring the web to see how to do this, and now I'm not even sure it's possible. However, it seems there must be way. What I want to do is create a function that will take x,y coordinates and tell me what MovieClip or Sprite is at that location. I want it to happen automatically, without any MouseEvents or anything like that.

I have flash where there is a link for song download. And, at the bottom of the flash I've a count, loaded thorugh flash vars which should increment everytime donload button is hit. Please let me know what approach should i take to do that. can i call a Java method on donload button which will insert a row in the table and and then get the count and render it to the count variable in my flash?
May be this extremely confusing. Here is a very similar example on how it is done. This is actually very similar to what i want to do. [URL] on this link there is count below which increments you hit the download button.
I am creating a selection of checkboxes that are supplied from XML. These checkboxes are to provide additional details to a background picture and therefore they each have a unique name and an eventlistener to add the extra details to the background picture. Depending on other buttons clicked on the stage, the list of checkboxes could change for the same background picture. I have a selection of 5 different background pictures all of which have a different list of checkboxes. I therefore want to load the checkboxes dynamically. When a button is clicked to change the background picture, I want to remove all the checkboxes associated with that picture and display a new set for the new picture.
I want to identify specific strings in a text box from user input to add to a score variable, like so -
[Code]...
The example given adds 1 to the score, but if a user adds a space then a second word the text box views it as a whole and not individual words, resulting in no values added to the score variable.The problem lies with the whole text box being viewed as one entire string. Instead, I want to split it up so word1 will add 1 to the score, word2 will add 1 to the score, etc.
I want to do something where I collect functions to be invoked later when a certain condition is met. E.g.
function doSomething(someArg:Object):void { if (conditionIsFalse){ operationsToDoWhenConditionIsTrue.push(function(){ doSomething(someArg);
[Code]...
Basically if doSomething is called twice, I only want operationsToDoWhenConditionIsTrue to hold the most recent invocation. Obviously since the invocations are wrapped in function(){} all the functions are the same. Is there any way I can accomplish what I want?
How do I determine what objects are underneath a given x or y coordinate on the stage or within a sprite? Preferably, I'd like to be able to do this so that a class that extends Sprite and is a child of the Stage can determine what's underneath a given x coordinate of itself, regardless of position on the stage. This has to be done without user input.
I'm not clear on what methods might make sense for this. The hitTest stuff requires more info than I'm likely to have. Maybe localToGlobal, but to use that, I need to know what the objects are already. There are a finite number of them, so I could have them testing for this all the time, but that doesn't seem right and may not even get me what I'm looking for.
