Getting started with Parsley - Part 1
Parsley is an MVC framework for Actionscript 3 and Flex projects. It uses dependency injection very much like Robotlegs. In this first video I show you how to get things set up.

Eclipse syntax color themes for FDT
If you haven't looked for this lately you are going to be really happy to see this eclipse plugin. For at least a couple of years I was hoping someone would build a plugin for managing themes in eclipse. We all tend to not like the default no matter what language you program in. The process be for was going into the Appearance tab in Eclipse and changing the color settings to reflect the needs you have, export preferences and then import every time you switch work spaces.
Well check out eclipsecolorthemes.org. This plugin adds a section under the Appearance menu in Preferences. You can brows the site and search for popular themes. My fav in TextMate has always been Twilight so I did a search and found one that was perfect, downloaded the theme and imported it with no issue.

Flex 4 Scroller using pure Actionscript
I had to figure out how to use the new Flex 4 scrolling using pure Actionscript over the last day or two. It isn't obviouse what the set up is right away without seeking out some documentation or posts by other users.
The MXML version would lead you to believe that you you would just addElement() to a scroller object and you would be good to go.
<s:Scroller left="2" right="2" top="2" bottom="2"> <s:Group id="vp" horizontalScrollPosition="57" verticalScrollPosition="198"> <mx:Image source="http://sites.google.com/site/hansmuller/Home/archive/gyro-original.jpg"/> </s:Group> </s:Scroller>
Here is an example of adding a scroller to a VGroup in pure AS3.
_vgroup = new VGroup(); _vgroup.gap = 0; _scroller = new Scroller(); _scroller.percentHeight = 100; _scroller.viewport = _vgroup; this.addElement(_scroller);
As you can see you create the component instance that you would like to apply the scroller too. Create the scroller and tell the scroller what component it is going to use for it's viewport and then you add the scroller to the display list. Doing this takes care of adding the component that you will be scrolling to the view for you. Pretty nice way of doing this but not the most obvious.
