Actionscript 3 :: Way To Tell Canvas To Dispatch Event Only If Not Over Child?
Oct 2, 2011
I got a square component inside a canvas which when clicked shows a glow effect-indicating selection-while clicking somewhere else this effect is removed-indicating deselection.The problem is that the canvas always dispatches the "deselect" event, even if the mouse if over the square.I worked around this by defining a circumstantial function which removes the child's width,height from the parent's "clickable" area.Is there a better way to tell the canvas to dispatch his event only if not over the child ?
I'm trying to do now is to make the application auto click on the first thumbnail,[code]I've been trying to google it and found that maybe I'll have to add an event listener to know when the thumbnail is actually being added to the stage, and just then click on it.I just found out that the code that Ascension Systems provided worked, but it didn't work at first because of a different error I had,the thing is, I'm working with the youtube API, FLVPlayback and such,And Each one of them is in a different movieclip,In the youtube movieclip I added this function:[code]I am setting the player as an object in the beginning of the script like so:var player:Object;
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.
In my AIR application, I try to dispatch a custom event from a class to main window.This class is use to call httpservice. My goal is to send a custom window when the httpservice result is send.[code]...
The problem is I get Error: Error #2094: Event dispatch recursion overflow. Why does removechild keep getting called if this.parent does not exist? Why doesn't removing event listeners work?
I have an event listener for a custom event type. This custom event overrides the clone method as required.In this event listener I want to dispatch an instance of a different type of event... a different custom event instance altogether. It also overrides the clone method as required.The problem is I'm getting a type coercion error: TypeError: Error #1034: Type Coercion failed: ...I do not know what is trying to do the casting. My code is:
/* elsewhere in a method */ addEventListener(GestureEvent.GESTURE_SCALE, handlePinched); /* the event handler */
I cannot remove a child. I get "Access of undefined property" when trying to compile.
I basically place a movieClip on stage. That movie clip has a custom class which load a video and when the video is done playing it dispatches and event which is picked up by the class that added the child. I want this class to then remove the movie clip but it doesn't.
So this is the function in the document class placing the child ...
ActionScript Code: private function myVideo(evt:Event):void { var myVidContainer:MovieClip =new cls_video();
I'm trying to figure out how to resize a child canvas but I can't quite figure it out. I have a bunch of mini canvas' around a parent canvas like this:
I am trying to develeop a Graph Structure with drag and drop features in Flex. I have to connect various components/children on the canvas. Once i drag n drop the components on the canvas, i am using SystemManager event handlers to draw connectors between the components. But, as i click on one component and drag the mouse, the line is drawn on the canvas as long as my mouse stays only on the canvas. If the mouse moves over a component/child(that has been dragged and dropped onto the canvas), the line is drawn to the origin of the canvas from the first clicked component. How shud i recognize the component when i move my mouse over the component? I want the line to be drawn connecting the components once my mouseup event is called.
I have an application with a viewstack that contains all the components that need to be displayed. The navigation is defined in the main application. All the components are based on canvas. The main application looks like that:
Having read about Container creationPolicy (thanks all the references in StackOverflow)I have a TabNavigator and AS code in the initial Tab needs to reference components of second tab (a Canvas with multiple children).But the components of the second tab are null until that Tab is rendered.
According to the documentation as I read it, I should be able to set creationPolicy on the second tab/Canvas to "all"; the TabNavigator will instantiate all its top-level children, even with its multi-view creationPolicy="auto"; and I was hoping that when creating the child Tab/Canvas, that the creationPolicy="all" of that single-view Container would be honored.
But it appears that this is not the case; if the TabNavigator has creationPolicy="all" then the second Tab is populated (but so are the third, fourth, ...); but with "auto" the second Tab is created, but not populated, even though its creationPolicy="all".Is there a way to get just selected Tabs to pre-instantiate?
I believe this is trivia question but here it is.I have created class which loads some image and takes fragments of each for certain animation.And in flash stage where I instance classes, I need to know when loading is complete. How do I proceed that info, I presume dispachevent do that, but how?
How do i create a trace that can detect if an event dispatcher is dispatching an event?....my problem is i've created a custom event that is not being dispatched i use this custom event in other applications and have verified that the code is correct I'm not getting any errors neither it just dies silently
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:
[Code]...
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?
I have a class which makes a url request and stores data from that request. When the data is retrieved, parsed, and stored into an array, I'm sending a dispatch event which I listen for in my document class. In the event handler function in the document class, I'm accessing the array that was compiled from the class. The array inside the class has 15 values, however in my event handler function, I'm only retrieving one value from it, which is the last value in the array. I posted my code below. Is there a different way I'm supposed to use the dispatchEvent in order to retrieve all of the array values instead of one?
Class package com.src { import flash.display.Sprite;
I have small chess application which consists of cells and boards. When user moves an item to the board, I want the board cell to dispatch an event so Board can listen to it and call a listener[code]...
I'm trying to do an eventDispatch but the event isn't getting picked up.The dispatch is coming from swf B, and the listener is in swfNot sure if it's an issue because they are 2 files. Does anyone know of a solution?
Basically all I want to know is if there will be a hit on performance as I dispatch events more frequently, or if this is a trivial task for flash to complete.
I have a form with a search field. When user press enter key, I use httpservice to send a query to mySQL database. In some case (a lot) there are several record, so a new window is opening to show those record with a datagrid to let user chose the good result.
My problem is how to send selected information to the first window (with text field). I gess that dispatch event is the way but I don't found how to use
dispatch an event on every 'onProgressEvent' of an external display object loading.
Does dispatching an event frequently cause performance issues?
All I want to do is have a parent class listen for whenever a progressEvent has fired in my loader class, rather than setting up an onEnterFrame loop in the parent class to call 'get' methods within the loader - this seems inefficient to me seeing as onProgressEvents don't occur on every frame.
I dispatched a Custom Event from topic1.swf but its not reflect to main.swf how to do that...?.. is it not possible here... and how to access a public variable/method of topic1.swf from main.swf..
I have two buttons each in its own sprite now I want to listen for mouse overmout and click event on both. In a way that if you roll over button1 its color changes but at the same time button2 color changes as well.
To be more specific lets suppose I have a graphic button like map picutre for a country like UK and then I have text button for UK as well. What I want now is that when user either scrolls over UK map the map button color changes but at the same time the color for UL text button changes as well. same goes for click and out events for the two.
I have a class that loads a swf [AS] private function setupSwf(swfXML:XMLList):void { swfLoader = new Loader (); swfLoader.contentLoaderInfo.addEventListener (Event.INIT, swfLoaded); swfLoader.load (new URLRequest (swfXML.toString())); container.addChild(swfLoader); [Code] ..... I want the swfFinishedHandler() in the main Class to be called when the timeline gets to the dispatchEvent, but its not firing.
I don't know if i've been in front of my computer for too long, but I can't for the life of me understand why this doesn't work:
All i'm trying to do is dispatch an event from one class to the other, when I trace it out, it says the event is getting added, but the event listener isn't picking anything up.
