Putting all the pieces together

Posted on by Cal Evans

Dear Reader,

I have posted several posts on this blog that all derived from a sample app that I wrote to generate QR Codes using the Google API. So far I’ve only give you the individual pieces, this post is about pulling them all together and creating the application.

I have been working on this particular application since February. (I used it to generate the QR Code I sent to the lovely and talented Kathy for Valentine’s Day. (Yeah, I’m that much of a geek) If you are a regular reader then you will recognize some of the code and concepts that we have discussed previously.

The MXML can be found below this post, and a link to the FXP can be found just above it. If you have Flash Builder 4, grab the FXP and you can import it and see all the code.

Custom Events vs. Callbacks in ActionScript

Posted on by Cal Evans

Dear Reader,

Bear in mind that I still have only a small amount of experience in Flex and ActionScript. This is more of a straw man post than a definitive guide and I welcome thoughtful criticisms and comments.

Both callbacks and events allow us to respond to events, the difference is how and to an extent, how complex. Custom events are a bit more complex to code and maybe that is why I see callbacks as more useful on a day to day basis.

Flash Builder 4 Data Wizard for HTTP Services – A love story in 1 act

Posted on by Cal Evans

Dear Reader,

Disclosure: I work with Blue Parabola, Adobe is a customer of Blue Parabola.

If you’ve been paying attention, you will have noticed that I recently published a series of articles over on phparch.com discussing the new Data Connection Wizard for PHP that Adobe has built into Flash Builder 4. While I am not a great fan of Wizards in general, I recognize that there is a segment of the developer population that does like them so I respect that and try not to run screaming from the room every time I see someone using one.
