    <p>Before calling the function <code>addNodeFilled()</code> that uses an external bitmap file as a fill I must load the bitmap file in flash player using Loader class and wait for the loader to finish loading and fire <code>Event.COMPLETE</code> and execute the corresponding event handler <code>onComplete()</code>. To ensure this I have a while loop to wait for completion of loading in <code>addNodeFilled()</code>, but when running the program the program esp the loop goes on infinitely which means in flash the event handler is executed synchronously with the main sequence and can't execute until <code>addNodeFilled()</code> ends. Usually the code in <code>addNodeFilled()</code> is placed inside <code>onComplete</code> event handler but I am unable to do that and need to call <code>addNodeFilled()</code> whenever I wish but check for load completion, how can I do that?</p> <pre><code>var stitch:BitmapData = new BitmapData(16, 16); var loaderStatus:String = "busy"; var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete); loader.load(new URLRequest("file:///E:/Projects/FlashDevelop/Terracotta/assets/Stripe.jpg")); addNodeFilled(100, 100); //function definitions=============================================== function onComplete(event:Event):void { stitch = event.target.content.bitmapData; loaderStatus = "loaded"; } //onComplete function addNodeFilled(posx:Number, posy:Number):void { while(loaderStatus != "loaded") { trace("waiting for loader"); } var grid:Rectangle = new Rectangle(5, 5, 5, 5); var nodeDecal:Sprite = new Sprite(); nodeDecal.graphics.beginBitmapFill(stitch, null, true, true); nodeDecal.graphics.drawRoundRectComplex(posx, posy, 80, 16, 0, 0, 4, 4); nodeDecal.scale9Grid = grid; addChild(nodeDecal); } //addNodeFilled </code></pre>

    1. COCan't you move addNodeFilled() call to onComplete(event:Event)?

    2. COAs I have already said that placing addNodeFilled() inside the event handler function is how its usually done but I can't because addNodeFilled() needs to be called again and again as and when new nodes are needed with different position parameters using the same user supplied bitmap image as fill. This situation of being forced to put the operative function call (here addNodeFilled) inside event handler function is limiting as it can be called just once with same parameters, usually the ensurance that something is done, that the operative function depends on, needs to be ensured once.

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
