Flex Spinning Progress Indicator Component
Sometimes you need to indicate progress to users when the application is doing something, like calling a remote web-service or something. At times, it can be nice to incorporate this as an element in the UI, that operates in an unobtrusive way. For instance showing a small indicator on or besides the button, that initiated [...]

IDEAs Deep Flex-Mojos Support
If you are writing Flex applications using IntelliJ IDEA, you should also choose the Flexmojos maven plugin for building (if you build with maven, that is) and not the other alternatives. Why? Well, for once, it seems to be the best plugin around for flex building, but also because IDEA has deep support for it. [...]

Just a quick note or advice. When using the Image component as a drop-in item renderer in a Flex DataGrid, there are things to remember or know about sizing. You can give the individual columns a width setting of their own, but the row height is a little different: either (a) set rowHeight of the [...]

Flex-Mojos keepAs3Metadatas Option to Apply keep-as3-metadata Compiler Option
If you use the flex-mojos plugin to compile flex code in a maven project, you might have the need to apply the -compiler.keep-as3-metadata option to the compiler, like I did.

Docked ApplicationControlBar Is Not In Children List
Here is a funny thing about how ApplicationControlBar acts differently as a child when docked and not docked. I had to write some code that traverse the complete tree of components in a flex application, and that was when I first discovered about rawChildren lists.

4 Things To Hate About PureMVC
Previously, I have written about how puremvc takes a stand on patterns of gui architecture while Cairngorm does not. I have also proclaimed to colleagues, that I do not find puremvc especially great, but at the same time find it “good enough”, which is to be understood as: The current contenders are (were?) not any [...]
