Actionscript :: Flex - Know When The Source Property Of An Image Is Completely Updated
May 31, 2010
[Code]...
I am presuming this is because the image hasn't finished reading the png file off the disk yet. What event can I monitor to know when it's width and height will have the right values? The 'Complete' event only seems to work for DOWNLOADED images. The 'Render' event happens EVERY FRAME. The (undocumented?) 'sourceChanged', happens as soon as source changes, and has the same problem! What event do I watch that will let me know when the image's width and height properties will have valid values? Or is there some Synchronous version of I.source='xxx.png', that I don't know about?
P.S. Yes, I know I shouldn't use "C:" in an Air Program. This was just for illustrative purposes, so that you won't suggest I use "Complete", which never even seems to fire when the file indicated by source is local.
I am changing image through flex every time i change it saved into server directory with same name(which i am referring to show). So when i refresh my page my browser didn't send new request to server since it's already in request.so didn't getting new image.Tip:- when i clear browser history it will come with new image
Can we put [Bindable] on functions/methods? I know that bindable is used to change the value of the source property to destination property. But not sure if we can use that for methods. why we cannot put/ if we can then what will be the outcome?
I am working in air application , i need to know how to add event listener when any object is updated,how can i implement this.Example:i have Class name Vehicle, and child class are Car,Bus,Bikes,Scooter,..etc, child class also have many properties like color,model no,....etc
I have array collection and AddChild() method in Vehicle class by this, i will add, child class to the vehicle class.I need a event listener which can trigger if any of the property is updated or changed in any of the child class property, how can i implements this in Flex3.
I have what seems a straighfoward situation: I update the source property of an image, when the image is loaded i want to redraw the border skin to fit the new size of the image.
newImgEdit.addEventListener(Event.COMPLETE, loadImgComplete); newImgEdit.source = myurl_ressource; private function loadImgComplete(evt:Event):void {
I want to change the image at click event.I change the source of the image on click but its not reflecting immediately it comes when any other event is fired.
In Flex, how to assign swf as image source at runtime, not embedding it.[Bindable] public var myImg:String;<mx:Image id="intImg" source="{myImg}" width="96%" height="96%" />In my application, I fetch image url dynamically from a web service call, and assign it to "myImg". But until I don't get the response from the web service call, I want to show a loader swf in image control above. I assigned something like:myImg = "assets/AS3.swf";and the path of swf is correct, but it doesn't show up.UPDATE:The code I've shown above works perfectly in a Flex 3 app but the swf does not show up in a Flex 4 app. Is it because Image control has dropped the support for swf in Flex 4 ?
I have an image which its source depends on a bindable property of another object.I'd like to know when this source changes, for example, by capturing the bind event or another related event of the Image control.
I would like to display an Image using a Bitmap as source. I've looked at many websites and most suggest something akin to this but somehow it still doesn't work....img1 works fine... But img2 doesn't load for some reason.
private function onComplete(event:Event):void{ bytes = event.target.data; img1.source = _bytes; /*this last bit works*/[code]....
I have a TileList that's loaded with data from Flickr. The tilelist uses an imageRenderer to make a bunch of thumbnails. I'm trying to create a custom drag and drop function, but I want to get the image source of the tilelist mouseEvent target. Here's what the code looks like for the drag handler:
i have a Air Project in which i have added three extenal source folders. but when i reopen project or strat flash builder again i get icon on those folder like this but when i open the configuration for that project and try to validate the path and adding it again i get message like this but the path is valid. proof is this pic what could be possible error,,, is there any way that i when ever re-open project i get no warning and able to navigate through the linked source code. now i am doing it
So inside my src folder I have my app.mxml file. I have a source directory pointed to my actionscript library.It appears that Flex does not look inside that source directory including an .as file within the master mxml file.
I could just have the main app.as file inside the src folder along with my app.mxml file but it would be nice if it could live in the actionscript library.
MCtext is a collection of text with frame labels. It's labeled as MCtext
The menu buttons tell MCtext to play the frame label as the button clicked. This *used to work*, but Flash was laggy as hell so I updated it. Now the same code returns #1009: Cannot access a property or method of a null object reference. at MCmenu/itemClicked()
Code: function itemClicked(butn:Event):void { parent.MCtext.gotoAndPlay(SomeArray[butn.currentTarget.label); }
I've tried just using a frame number, but still the same #1009
I've tried the Script Assist to target the MC on the stage: using root.MCtext... still the same #1009 using this.MCtext... returns a #1010

I'm having a problem with getting a backend script to append an xml file after the client has uploaded a new image. A serate swf will read the xml to update banners
I got the image uploader to work but can't figure out the xml.

Code: // First thing is to set the flashing upload message clip to invisible uploadMsg.visible = false; // Set the URL for the PHP uploader script
i am trying to modify during runtime an image in my application, this image is located inside assets folder, so thats why i dissable -use-network=false flag, then i call something like this:img.source="../assets/pict.png";but it's not working.
From a component I am working with.....If the target object has a property called source, which is used to set the path and file name of the media file to be loaded, then the list component will automatically set that source property."I am a little confused by what this really means.
I have made a game, using a new cursor image,But for some reason it's showing both? The cursor and the image? How do i lose the cursor image completely?
I have a slide show script, which works, but as of now, the image will completely fade out before the next one fades in.What I want is for the next image to start fading in before the previous image completely fades out.
Does anyone know where to find examples, tutorials or source files on how to integrate flash with backend to create a dynamic image gallery that can easily be updated?
I am drawing a cellular automaton simulation on a Flex Canvas. I alternate computing the state of the automaton with updating the graphics on the Panel. However, the updating of the Panel does not seem to be "keeping up" with the update of the CA state.
I'm wondering whether I am doing something wrong with my handling of the graphics code. The code is below. Sorry it's so lengthy, but I don't think the problem will happen with anything simpler (well, it probably will, but I'm not certain I want to take the time to find it).
problem-1:In php we can easily move one page to another and easily use different type of function from those pages.In flex3 how i can use different type of .mxml pag
In the code below, the presentedAlbumIndex is used to control the selectedIndex of the TileList. Item "five" is initially selected. Whenever the button is pressed the first item in the array is deleted, and the presentedAlbumIndex is decremented.
In theory, the selected index should stay with "five" every time the button is clicked (until "five" is itself deleted). It works this way for the first button press. However, on the 2nd button press the highlighting changes to "six" for some reason. Also, the TileList selectedIndex is always one behind.
I tried looking into ListBase and monitoring selectedIndex. It looks like the selectedIndex is updated initially to the correct index, but then it reverts back at some point to the correct index+1. I do not know why it's setting back.
It seems it's due to the fact that I am doing a data provider delete and index change in the same operation.
Is there some function in TileList I could override to keep selectedIndex up to date?
