    <p>I'm new to AS3 and I'm doing some custom video player video project for AIR. While I was studying the simple examples (non-StageVideo) on how to play videos, I've encountered a unique situation where I got an awesome auto-scaling (stretch-to-fit) to window behavior from Flash.</p> <p>Whenever I set the SWF directive's width and height equal to the width and height of the flash.media.Video object I'm creating. It does the auto-scaling, stretch-to-fit, resizable behavior. Like so:</p> <pre><code>// SWF directive placed before the class declaration of the main class [SWF( width="1024", height="576", backgroundColor="000000", visible="true" )] // somewhere in my initialization myvid = new Video(); with( myvid ) { x = 0; y = 0; width = 1024; // if I set this wxh equal to wxh in the SWF directive it auto-scales! height = 576; } myvid.attachNetStream( myns ); addChild( myvid ); // must come after instancing of video and netstream, and attach to make the auto-scale work myvid.play( "somevideo.flv" ); </code></pre> <p>Even if I set the width to 16 and height to 9 on both it scales and fits perfectly on the size of my window. <strong>Can some explain me this behavior? None of what I read in the documentation mentioned this.</strong></p> <p>Don't get me wrong, I like this behavior! :) It made things easier for me. But code-wise I need to understand why is this happening as the code I set had nothing to do with auto-scaling.</p> <p><strong>Also, what the heck are directives for? Don't they just have pure ActionScript 3 equivalent? They look hackish to me.</strong></p>

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.
