First, yes, screen readers can read Flex applications. And yes, its fairly
easy. But, I’ll discuss how in a future post.
But, if you’d rather send people to your old HTML version of your site when
using a read, there is good news. Flash Player has the ability to detect if a
disabled and/or the Flex application is not compiled as an “accessible
swf”. This is possible with the Accessibility class.
It is important to note that if the Flex application is compiled as an
“accessible swf”, the screen reader will also be able to read content in
the swf. If not, the screen reader only reads the words “flash movie
start” whenever you interact with it. Talk about a usability buzz kill.
So, here is the code to see if a screen reader is currently running (not just
installed) and then adds a LinkButton that call... (more)
The fear, uncertainty and doubt (FUD) is been slung around by profiteers like
folding chairs at a WWE event. The haters are still being haters. Nothing new
developers to start using their HTML5 software.
The context is all wrong here. Very, very few Flex developers have shifted,
moved, changed over, or whatever you want to call it… to HTML5 (or anything
There is not a move to HTML5
I will go as far as to say that there is not a move to HTML5. The simple fact
is that, developers are being develop... (more)
For over a decade now, we have been trained to use the "back" and "forward"
buttons in our Web browser to review or backtrack previously viewed content.
We are trained to the point that there are even keyboard shortcuts.
Unfortunately, this can be a problem when browsing Flex applications. Being
the well-trained users that we are, we often forget that we could cause the
Flex application to reload unwittingly.
Fortunately, there is a solution that is built into the Flex SDK and HTML
templates that are generated in a Flex Builder project. By default, Flex
enables history managemen... (more)
Having built/architected/developed/consulted many Adobe Flex applications and
being one of the first certified Flex instructors in the world, I’ve seen a
lot of Flex applications. Some good, some bad.
But no matter how many applications or who I’m talking to, I always stress
the importance of securing proprietary information. By securing, I mean
don’t put it in your application. Unless your are encrypting your
application and decrypting at runtime, you are subject to a decompiler
exposing your secrets.
There are Flash decompilers that will take any SWF and give you the source:
Adobe recently released (August 2009) the Flex implementation of PMD tool
which is extensively used at J2EE shops for code quality management. FlexPMD
is a tool that helps to improve code quality by auditing any AS3/Flex source
directory and detecting common bad practices.
The Flex PMD tool is locate on the Adobe Open Source Projects site.
It is available as an ANT task, command line and Mac OSX Automator.
And before you ask, no, there isn’t an Eclipse plugin… yet.
