    <p>Why don't you use stage.stageWidth and stage.stageHeight for positioning purposes?</p> <p>EDIT: Ok, here's an example. I'm considering that you'll place this code inside the container where loginBox also resides. The stage property is undefined unless your object is added to the DisplayList, so you need to listen for when it's added and then position the loginBox.</p> <pre><code>// in the constructor this.addEventListener(Event.ADDED_TO_STAGE, onAddedToStage); </code></pre> <p>and then </p> <pre><code>private function onAddedToStage(evt:Event) { loginBox.x = (stage.stageWidth - loginBox.width)/2; loginBox.y = (stage.stageHeight - loginBox.height)/2; } </code></pre> <p>Also, if you have stage scaleMode set to noScale (which maybe is the case), if you need to constantly reposition the loginBox based on browser resizing, you need to listen to an Event.RESIZE event</p> <pre><code>stage.addEventListener(Event.RESIZE, onResize); </code></pre>

    1. COI don't know why, but I have an aversion to JavaScript and avoid it where possible. I went through my code and got stage.stageHeight to work. Sort of. I was getting an error message for an invalid property or method, so I added the following: override protected function updateDisplayList( unscaledWidth:Number, unscaledHeight:Number ) : void { super.updateDisplayList( unscaledWidth, unscaledHeight ); myStageWidth = unscaledWidth; myStageHeight = unscaledHeight; } I'll have to try it on my desktop and see if everything is healed.

    2. CObefore accessing the stage, it must be added to the display list. You must first listen for Event.ADDED_TO_STAGE. Inside of the method that fires when Event.ADDED_TO_STAGE is dispatched you may then use stage.stageWidth; Otherwise you will get an error. A common work around is to check stage in the constructor, if you cannot access it, or it is null, then you listen for Event.ADDED_TO_STAGE, both resulting in an init function. if(stage) _init(); else addEventListener(Event.ADDED_TO_STAGE, _init); private function _init(e:Event = null):void { //You may now access stage }

    3. COPart of my structure has an application loaded through the use of an SWFLoader. I found that this sub application detected width as 1440 but height as 802. I'm guessing that has to do with toolbars. That application also loaded a gameplay demo into itself, but this one detected the width as 500 because it's container didn't have dimensions specified. I started having the primary application do the check and distribute the numbers using LocalConnection, but in the end, used a Shared Object and set up the other two applications to access it as needed.

A row detail

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
