    <p><code>activate</code> event is inherited from EventDispatcher (the default implementation of event dispatching class present in the player runtime). This class is usually extended by other classes if they want to be able to dispatch events. This particular event is dispatched <a href="http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/events/EventDispatcher.html#event%3aactivate" rel="nofollow"><em>"when the Flash Player or AIR application gains operating system focus and becomes active"</em></a> Note that it is a broadcast type event, which means that you don't need to listen to any particular dispatcher, it is invoked on any existing listener.</p> <p><code>addedToStage</code> is dispatched <a href="http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/DisplayObject.html#event%3aaddedToStage" rel="nofollow">when the listener is added to display list</a> (it's properties such as <code>stage</code>, <code>parent</code> and <code>loaderInfo</code> are populated and, potentially, it can start receiving interaction events, such as mouse events, touch events etc.) This is one of the basis events available to all display objects.</p> <p><code>viewActivate</code> is a specific to mobile devices event dispatched by classes inheriting from <code>spark.components.View</code>. So far I understand, it is dispatched once the view (which dispatches it) becomes visible to the user.</p> <p><code>creationComplete</code> is a specific to Flex framework event. It will be dispatched by View class mentioned above, because it is an extension of UIComponent, which is the core component of the Flex framework. This event is dispatched <a href="http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/mx/core/UIComponent.html#event%3acreationComplete" rel="nofollow">once all of the components properties declared in MXML template were set</a>, the component finished it's validation cycle, being laid out etc.</p> <p>Most unfortunately, according to Adobe design you must use Flex framework in order to access certain features on mobile devices. This is why you have that lot of initialization events - the Flex framework is bloated with redundant or very similar classes, functions etc.</p>

    1. COThanks for your reply. But I am a little confused what is the difference between add to the stage of display list (addedToStage) and display it or make it visible (viewActivate)? And why the first time I run my app, it did not call the activate function?

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.
