    XML preloader

    I have a question

    I have a slideshow loading XML data. The XML file is pretty simple: image, title, desc, link X 4.

    What I need is a preloader that looks for when the IMAGE is loaded and not the XML file. All I could find was for preloading the XML file, which I dont need.

    I want to listen for when the image is loaded, then once it is loaded add the text and other components to the stage.

    Can someone direct me to some good info out there?

    All you need to do is add an event listener.

    myLoader.contentLoaderInfo.addEventListener(Event. COMPLETE, compHandler);
    function compHandler(event:Event):void
    {
    //all your text etc here
    }

    I am doing a bit of guessing, since you did not provide any code.

    Thanks cancerinform,

    I think that is what I was looking for. But if I am to display a preloader as well, would there be a different approach?

    I could always fake it and have the preloader in the background and have the image overlap, but if there is a different way I would be happy to know!

    Thanks

    So now it works perfectly locally, but when I upload it, the images either dont load or appear and disappear right away.

    DO you know what is going wrong? I cannot figure out :-(

    Loading the first image:

    Code:
    xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);
    
    function xmlLoaded(event:Event):void
    {
    	xml = XML(event.target.data);
    	xmlList = xml.children();
    
    	loader.load(new URLRequest(xmlList[0].image));
    	texts_mc.title_txt.text = xmlList[0].title;
    	texts_mc.desc_txt.text = xmlList[0].desc;
    	xmlLink = xmlList[0].link;
    
    	loader.contentLoaderInfo.addEventListener(Event.COMPLETE, compHandler);
    	function compHandler(event:Event):void
    	{
    		addChildAt(loader, 1);
    		bar_mc.play();
    
    	}
    
    }
    Then playing the slides:
    Code:
    	loader.addEventListener(Event.ENTER_FRAME, loadImg);
    
    	function loadImg(event:Event):void
    	{
    		if (bar_mc.currentFrame == 30)
    		{
    			loader.load(new URLRequest(xmlList[i].image));
    			TweenLite.to(loader, .5, {alpha:1});
    
    			loader.contentLoaderInfo.addEventListener(Event.COMPLETE, compHandler);
    			function compHandler(event:Event):void
    			{
    				trace("loaded");
    				addChildAt(loader, 1);
    				bar_mc.gotoAndPlay(1);
    			}
    			texts_mc.title_txt.text = xmlList[i].title;
    			texts_mc.desc_txt.text = xmlList[i].desc;
    			xmlLink = xmlList[i].link;
    		}
    	}
    
    }
    This is only the part of the code that loads the images. If you need to see the whole thing let me know.

    Also when I trace, it gives me a weird result (trace "i" and when it give the complete handler) It repeats I dont know why? Maybe that is the part that is bugging?:

    Thank you bilgaraden.

    Do you guys think it would be because of this event listener the issue:

    bar_mc.addEventListener(Event.ENTER_FRAME, loadImg);

    I need to present this tomorrow and I feel helpless right now...

    So if I remove the event listener for the loader to load, it works, but then I am back to square one with NO preloader. Is there a way to create a preloader or an event listener that only plays the bar once the image is finished loading?

    Actionscript Code:
    bar_mc.addEventListener(Event.ENTER_FRAME, loadImg);

        function loadImg(event:Event):void
        {
            if (bar_mc.currentFrame == 30)
            {
                loader.load(new URLRequest(xmlList[i].image));
                TweenLite.to(loader, .5, {alpha:1});
                //addChildAt(loader, 1);
                bar_mc.gotoAndPlay(1);
                trace("loaded");
