ActionScript 3.0 :: Unable To Catch IOErrorEvent Thrown By ScrollPanel Component
Aug 13, 2009
I have a ScrollPane component instance that I expect to throw an IOErrorEvent as it tries to load a file. Essentially, I want to set it up to look for one file, and if it doesn't find it, it throws an errorEvent and then I handle that by looking for a different file. I understand that the ScrollPane doesn't throw a standard IOError when this happens because the load is asynchronous, and that I need to listen for an IOErrorEvent.IO_ERROR event instead. I've attached a listener for this on my ScrollPane, but it doesn't seem to ever catch the event. Here's my code:
I have a picture loader to load pictures on a website I am making and I want it to check for a picture and if the picture is not at the url, I want it to run a function and not throw an error. I tried using try catch but it didn't work so I tried using an IOEventListener and that still didn't work.
I'm very novice at actionscript 3.0 so I can't handle custom components so I just use components given to me through flash professional. I want to scroll through a list by clicking down and moving mouse up and down (Almost like touchscreen model scrolling eg. iphone, andorid, ipad). I've tried startDrag() after adding EventhandlerI(ListEvent.ITEM_CLICK) to the list but it would start dragging the WHOLE list not through the data in the list. If my explanation isn't clear enough I'll be gladly be able to answer your question! So basically I dont want to see the scrollpanel skin on the right. If there is a way create this scrolling effect any way possible.
In Flash AS3 i wanna write the single try catch block in order to catch any errors in whole class. For ex, i have a lot of functions in myClass.as. I don'w wanna write in each function try catch blocks in order to catch errors in this function. Is there any methods to do this?
Is there a way to create an automatic slideshow gallery that is controlled by the thumb position on a scrollbar?
I'm a FLash AS3 noob and I'd like to place an article or story inside a scrollpanel. At certain points of the story, I'd like the thumb (on the scrollbar) to trigger an event that transitions to a new image inside the slideshow gallery.
Im trying to get rid of the track that is used in scroll panel. It seems that I have no way to remove it.I tried checking visible to false,alpha=0,and color to white. It wont affect the skin track at all in the scroll panel.
I have this scrollpanel that gets its source from another container that builds content dynamically from an xml. So the content is in the scrollpanel with scroll. No i want to auto-scroll the content depending on the mouse position within that scrollpanel
[Code]...
the result of this is a flickering of the content.
We are the developers of a complex Flash component (url...) which worked without issues on Flash CS3 and CS4. Now, in Flash CS5 (both Mac and Windows versions) we have found a couple of problems at author-time
-1- After installing the mxp file containing the component, when trying to drag the component from the Components panel to the stage, or to the Library panel, it doesn't work. There's no way to import the component!
-2- If we open an existing FLA (created with Flash CS4), the component doesn't show correctly at author-time: you only get a black frame, instead of the expected result (it should show a white background with a logo in the middle). When compiling, everything works fine.
I made an as3.0 website in Flash cs4. [URL]The content of the pages is placed in a ScrollPane component, that comes with cs4. It all works fine in Chrome, Opera and IE but Firefox and Safari only show the top-left 100x100px.
Here's how it works.index.html holds a variable that tells my flash where to go (agenda, djs, bookings etc.). index.html loads preloader.swf via swfObject. Preloader.swf loads theKitchen.swf and passes a variable to it so it knows where to go, and triggers the init() function.
Code:
var loader:Loader = new Loader(); var go:String; public function Preload():void {
[code]...
In the "mainswf" then comes some if/else statements to build the desired page. If you click a button in the menu a function is triggered with an if/else statement that checks if the page that belongs to that button isnt allready shown. If its false the source of the ScrollPane is set to that page.Every page is build in a seperate class. The class ready an XML file that holds all the text/urls to images/ video.
In my Flash Builder (Flex) 4.6 app, I just noticed for some reason all my "s:Window" components will not allow me to click and select anything in design mode in flash builder!
My other non-window type components are fine - I can open a TitleWindow or Group for example and click on the various fields and labels no problem.
In my Window components, I can select an item in the 'outline' window, but not using the mouse and actually clicking on the component in the visual design window. When I click in there, it looks like it's selecting the actual 'window' box. Almost like it needs to be 'sent to back' or something.
Recently I configured my BlazeDS to use Array instead of ArrayCollection for performance reasons. Additionally I adjusted my templates to generate Array properties.Everything wen't fine. All except one function that causes TypeError: Error #1034. These are being thrown before the result callback is called. It claims to have problems casting an ArrayCollection to Array. I removed the generated types to make Flex use Objects instead, but these did not contain any ArrayCollections. My question now is: How can I get the stack-traces of errors thrown in event-handlers? I allready added handlers for unhandledExceptions in all of my modules and they are called if errors occur in code triggered from user-interaction, but they don't seem to be able to catch stuff thrown by event-handlers.How can I track these Errors?
PS: The classes are: package de.upw.ps.ucg.model.ucg.scheduler { [Bindable]
I have this code: function LoadLogo():void { parent_container = new Sprite(); addChild(parent_container) var path:String = "images/logo.png"; var req:URLRequest = new URLRequest(path); [Code] .....
Works fine in another file, but not here. The trace prints. The error never does...even when the path is deliberately incorrect. The trace doesn't print if it's in the first line of LoadedLogo. No error is ever thrown.
I am new in Flex, and I am trying to retrieve info from an external url's information. So right now I am using a call a url from another server when the user clicks on the link( this brings up the IFrame with the url embeded). If successful (based on arguments sent with the url) then a correct page will load up. But, if unsuccessful, ( i will get a exception error on the webpage embeded on the link i have given) then i need to display a pop up that says error and return back to the previous page. Is there a way to check if i am getting an exception error from the url site i am retrieving?
Is this possible to load the urls info first and if success then load, and if not bring pop up? ** additional note, I am trying to catch a servlet exception http 500. Below is a peice of the code, so when this component is called, by a click button, it puts this IFrame in the view contents with the url, but i want to know if the http status code is recieving 500, or 400 etc. so i can stop this call and load up instead a error popup.
I have a site I'm maintaining that consists of multiple pages that tween in their menus on a single monstrous AS2 timeline. I've broken the timeline into their own swfs that I want to now network with a swf loader and AS3 code. I've kept the timeline tween-ins, after stripping the AS2 code off all buttons. I put the AS3 code on the last frame of the timeline in an .as layer.So on the main page, on the last frame of the animation in an ActionScript layer, I put the following:
Code: var defaultSwf:URLRequest=new URLRequest("defaultHeadShot.swf"); var swfLoader:Loader=new Loader(); swfLoader.load(defaultSWF); addChild(swfLoader);
[code]....
I keep getting the Type 1009 error. I'm trying not to have to rebuild the graphics from the ground up, which it doesn't seem like I will have to do. I think it's probably got something to do with putting all the code at then end of these complex tweening timelines, and that a line of code that offers a scoping cue might be the answer, but I'm stumped.
The preloader I usually use executes an addChild(loadedMovie)statement in response to an Event.COMPLETE event from the loaded swf's contentLoaderInfo object (a common approach, I believe.) The problem with this (as many of us know) is that the loaded swf starts running before the Event.COMPLETE event gets thrown, which means that once the child is added, it is already a few frames into its timeline. What I need is a way for the loaded swf not to start playing til its COMPLETE event gets thrown.
I'm working on implementing communication between an Adobe AIR app and a browser Flash object, and the LocalConnection documentation mentions an asyncError as a potential event:
asyncError: Dispatched when an exception is thrown asynchronously — that is, from native asynchronous code.
However, that's the only documentation I can find on it. Does anyone know what this error actually means? I've searched around but couldn't find any reference -- most sample code I found does an addEventListener() for the asyncError but doesn't give any clue as to what it means or when it could occur (i.e. if it could occur when sending or when recieving).The Adobe documentation page also lists potential events for each method, but asyncError isn't listed under any specific method, only for the general class.
I have a skin that's base clas is GraphicRectangularBorderSkin (from degrafa). I'm using it as a panel skin. I'm using Degrafa 3.2, Flex 3.2. It throws a #1502 error (thrown when a script runs too long) every time. If I remove the line changing the em variable, the error goes away.The class is basically (although I paraphrased for the sake of clarity):[code]
1046: Type was not found or was not a compile-time constant: FullScreenEvent.Warning: 3594: getStackTrace is not a recognized method of the dynamic class Error.Warning: 3590: void used where a Boolean value was expected. The expression will be type coerced to Boolean.Does anyone have any experience with these errors being thrown?
I'm assisting my professor with a class helping students build an online portfolio. Yesterday, one of the students sent me a bunch of .fla files to review and I made some changes, inserted a bunch of comments in the code and told her to change the rest of her files into the same format. (Adding keyframes, frame labels and button codes, etc.)
Then she emailed me to tell me that she keeps getting this error message every times she makes a mistake and tries to "undo" something.
"Every time I open up the drawing page and another one of my subpages like logo design for example, I work on what you said to do, but if i make a mistake and undo it, I get this error message and all my images disappear completely from the time line. I have attached a screenshot of the error message, maybe you know whats going on but I'll keep working on it and try to not have to undo something because at the moment that seems to be the problem. I have to close flash and reopen everything to make it go away."
I have strange error which i tried to fix all day but with no result. The application is working fine in debug modus, but after I uploaded it to my server it throws following Error:
I work with Flash Pro allmost 11 hours per day and every while i get a error which messes up everything. Approximetly i get this after about 2-3 hours withevery project.After i get this error there is no chance to test movies afterwards.I see a fast flash of the loader window but it dissapears so fast i cant even really see if it is loader.
I hvae load "test.swf" file .If file not found how to show the dinamically not find file name.
var url:String = "test.swf";var loader:Loader = new Loader();loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler);var request:URLRequest = new URLRequest(url);loader.load(request); function ioErrorHandler(event:IOErrorEvent):void { trace("ioErrorHandler: " + event);}
I'm loading an image with Loader class, adding a listener to its LoaderInfo object like this:
ActionScript Code: var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(IOErrorEvent.IO_ERROR, ioErrorHandler); var req:URLRequest = new URLRequest("myUrl.jpg"); loader.load(req);
Then of course I have a function ioErrorHandler. How can I get the url within that error handler?
The IOErrorEvent doesn't have something like a url property, nore does the LoaderInfo has one. Well, I just though of getting my Loader object back within the error handler like this:
ActionScript Code: function ioErrorHandler(event:Event){ trace(event.target.loader); }
But well... I get runtime error #2099. The Loader object is not available in ioErrorEvent. Do I really need to parse the url from IOErrorEvent.message?
ActionScript Code: public static function toDisplayObject(encString:String):DisplayObject { var bytes:ByteArray=Base64.decode(encString);[code]......
In the main script I call this function with a base64 encoded image bytearray, which is a long string. Then the script tries to add the returned displayobject onto the stage. However, somehow, I'm getting Error #2044, the unhandled IOErrorEvent error.
I have a component "child" which has a cancel button. Now this component is placed in a state called "newChildComp" I also have another component called "parent". In the parent component, i have a button that dispatches an event. Here is the event code:
[Code].....
so, basically,i am checking to see if the cancel button component in the Child component, while i am still in the parent Compoent, was clicked, if it was clicked, call the cancelButtonHandler. The problem is by the time the addNewChild handles the event, that cancel button was still null. My question is how do i solve this without using the itemCreationPolicy on the cancel button?
