Flex, RIA

I had the opportunity to present a 4.5 hr lecture on Building Rich Internet Applications at ACM’s Compute 2010 today. We started out by defining what an RIA is and exploring the various RIA platforms available, we then further explored the Flash Platform in more detail, wrote some experimental code to understand the internals of Flash Player, looked at Flex 4 and its various new features and also spent some time understanding the Flex Component Lifecycle

Here’s the slide deck from beginning of the lecture which tries to define what an RIA is and explores the architecture a typical RIA platform …

Along with the Custom Components in Flex 4 presentation I shared yesterday, I also gave a 15 minute lightening talk at Adobe DevSummit on Keyboard Productivity in Flash Builder, this was just a quick show and tell where I walked people through various ways of what Jeff Atwood calls Going Commando … read more

Yesterday at the Bangalore Flex User Group Meeting after Khan’s excellent talk on LCDS3, Fiber and the Modeler Plugin we had some time left to so I decided to show everyone how cool and easy layouts in Flex 4 are ..

Here are two quick layouts we wrote during the meeting as I showed everyone how easy it is to write a custom layout …

Random Layout

Step Layout

These layouts are currently somewhat crude but the idea was to convey how easy it is to write your own layouts … here the code for RandomLayout … just one simple function … read more

Layouts in Flex 4 are decoupled from containers and its quite simple to define your own layout. Yesterday I wrote ConcentricLayout.

ConcentricLayout arranges layout elements in such a way that their centers are aligned and their size sequentially decreases. The width of each layout element is less than the previous element by a value specified using the horizontalGap property and the height of each layout element is less than the previous element by a value specified using the verticalGap property. If the element has an explicit width or an explicit height it still aligns its center but is not resized. You can tell the layout to force a resize of all elements and ignore their explicitly specified size using the forceResize flag

Here’s a quick example:
