Using TextFields and Bitmaps in a programmatic skin
There's not a lot written about using text fields (or any other display object) in a programmatic skin. What there is often suggests you have to add the text field as a child of the skin's parent. But it's actually a lot simpler than that...

The parentheses operator
It's not uncommon for less experienced Actionscript developers, particularly self-taught developers, to be a little confused about the purpose of the parentheses you put after a function name when calling the function. The most common question is why aren't the parentheses used when assigning a function as an event handler?...

If I had more time
One of the frustrations of being busy with client work is the lack of time to investigate, experiment and play with interesting stuff. One day I’ll have time to try all this stuff but until then, here’s a simple list of the flash/flex tools I’d like to play with. Maybe you’ll find something interesting here…

Improving Cairngorm’s ModelLocator Part 4 - The monostate
In the first article in this ad-hoc series I expressed my desire to replace the Cairngorm developers expressed preference for implementing the ModelLocator as a singleton with an alternative implementation as a monostate. … The monostate pattern describes a class that can be instantiated as often as one likes and where each instance uses the same set of data - there is only one state shared by all instances, hence the name…

Improving Cairngorm’s ModelLocator Part 3 - Hiding the singleton II
In the previous post in this series, I showed how we can use a second class to access the ModelLocator singleton. This enables instances of this second class to be created, modified, bound to and disposed of as often as one wishes while maintaining the integrity of the data in the core singleton. Each instance of the second class mirrors the data in the singleton, modifying the data in an instance modifies the singleton, and modifications to the singleton are immediately reflected back out to every instance of the second class…
