Simple drag n’ drop for Flex (ala iGoogle)

25 Jan 03:29
Long ago, on a project far far away, I was given the task of recreating in Flex the whole drag n’ drop functionality that was found on iGoogle.  And…. I did.  Then the code was lost and the classes forgotten. Well someone had been looking for this functionality on the web and came across an old [...

EventDispatcherProxy & ProxyEvent

12 Jan 10:06
Preface This is gonna be a ’stream of conscientiousness’ type post. Hopefully it will be rather easy to follow and not long winded. Might want to open this and follow along: example flex application In the Beginning One of my pet projects has been making an isometric (i.e. Diablo, Diablo II) game for Flash. Part of that [...

AppCoreLib

29 Dec 08:44
Preface For the longest time I have been using a little set of helper classes that I have just recently named AppCoreLib.  I have used this on various projects of varying sizes.  Everything from Enterprise level apps to my pet projects. Though not entirely original, the idea hasn’t really been put into an open-source swc that [...

ServiceLocator Quick Tip

22 Dec 04:55
Depending on your services setup, and if you use Cairngorm, you have probably seen or written alot of code like this: public function execute (event:CairngormEvent):void { var call:AbstractOperation = ServiceLocator.getInstance().getWebService("someName").getOperation("someOperation"); So suppose you have many WSDLs or if you are like me and are using AMFPHP, you might have quite a few Remote [...

Naming Conventions: My OCD is kicking in I think?

1 Dec 07:49
Preface While working on my current project, a coworker and I were discussing naming conventions. So I thought I would throw this out there for your intellectual consumption and maybe spit back some enlightenment, if you will please. This will be broken down into two sections/questions, the first dealing with instance names and [...

flash.net.FileReference & Mac OS Leopard: Not playmates?

17 Nov 02:19
[UPDATE #2] Thanks to the readers’ comments I got it working.  Yippee!!!  I just did an OS software update going from OS 10.5 => 10.5.1.  I did uninstall the flash player and then reinstalled it but that may be entirely unnecessary as the OS update may completely address the fix for the older flash player versions.  [...

TextInput gets a real RIA makeover

23 Oct 13:06
I have been working on a personal project for sometime now. It makes heavy use of forms and renderer type class. This means loads of mx:TextInput. The issue was that I wanted the effect of inline editing on a form that, at first glance, looks like any pre-filled data will just appear [...

Added example swf files to jwo_lib

2 Oct 11:07
Yeah yeah yeah. I know you are probably saying ‘Big Deal!’. Well it was long over due. Here is the links for you folks: http://jwopitz-lib.googlecode.com/svn/examples/example But there is that problem of it not properly rendering the html files in Firefox. Fine in IE but FF craps out. You can read a forum [...

Added ASDOCs to jwo_lib

1 Oct 12:56
Yes finally I have added ASDOCs to jwo_lib.  I am sorry it has taken this long.  It is still a work in progress too so if you see some things that just don’t jive, post a comment or give it a few days and it should be fine.   I am also taking this coming week [...

Default Styling & Embedded Assets w/ .as files

24 Sep 02:20
If you have done any custom component development then you have most likely attempted some level of default styling for your custom components. Very recently I developed a custom component for jwo_lib that required button skins located in a swf. I am not particularly too fond of following Flex’s default.css styling model [...
