Filter messages using the logcat command

GiorgioNatili — Sun, 13 Nov 2011 17:24:57 +0100

When working on mobile with AIR you cab use the logcat tool available in the Andorid SDK to grab information from the device and dumping them via USB on a log screen.
If you are interested to get only the trace statements and the ActionScript error messages you can restict the logcat output via command line with the snippet you find below.
The reason why you can do this filtering is because during the packaging process each AIR application has the word air added to the application ID, therefore using the filter I.air guarantees to dump all messages for the currently running AIR application.
The letter I stays for the Information priority level.

Add a custom StatusBar to a WindowedApplication

fedele.marotti — Thu, 11 Feb 2010 18:02:11 +0100

To use a custom component as a statusbar it's quiet easy,
just create your component using MXML or Actionscript, it's the same, and the add this line to your WindowedApplication

Skin the WindowedApplication

fedele.marotti — Fri, 20 Nov 2009 12:23:26 +0100

The following example shows you how to extends the ProgrammaticSkin and add an image as background of your WindowedApplication positioned at the center of the window;
usage :
WindowedApplication {

borderSkin: ClassReference("com.gnstudio.skins.ApplicationSkin");

}

File system tree root directory

Giorgio Natili — Wed, 30 Sep 2009 05:18:01 +0200

The following example shows how you can set the initial directory for the Adobe AIR FileSystemTree control by setting the directory property to a File object, which in this case is the user documents direcotry.

Dispatch events between native windows

Giorgio Natili — Sun, 20 Sep 2009 20:00:29 +0200

I was looking to a way to dispatch events between ultiple windows in an AIR application and, after I found on google only some solution that state to send a reference of the target for the event to the new window uing public properties, I came out with a more elegant solution that involves a new class added to nabiro.
The idea is that this class acts like a bridge on which is possible to register a DisplayObjetc for a specific message (i.e. the event type), the snippet represent only the simple usage of thebridge for register a new DisplayObject, attached there is the complete sample.
]]>

bridge = WindowsBridge.getInstance();
bridge.register(this, "Test");
				
addEventListener("Test", onTest);

// Window dispatch code
var test:WindowsBridge = WindowsBridge.getInstance();
					
test.dispatchEvent(new IntraWinComEvent(IntraWinComEvent.DEFAULT, new Event("Test")));
